My dell inspiron 15r 5521 when it shuts down it'd screen goes off but the lights stay on for about three minutes when the screen has gone off the only way to completely get the lights to go off is to hold down the power button for like ten seconds I know it's not good for it but sometimes when I'm in a hurry I have to this computer is like three weeks old so what's wrong with it also how do I keep wifi on when closing the lid is there a registry hack for that? And what is fast boot

The default "shut down" behavior on Win8 is to reboot the computer and then hibernate right before the login screen. This enables the "fast boot" you mention where the computer can be "started" (actually resumed) in seconds. The best solution to this is just never shut down (seriously, there's literally only a couple reasons to ever do this, and I don't think you're adding or removing hardware every time you run between classes...). Use sleep (suspend to RAM; near-instant both to suspend and to resume, draws a tiny bit of battery power but you can leave the machine that way for a week, usually) or hibernate (suspend to disk, takes a while - though it shouldn't be anywhere near 3 minutes - but then shuts down completely and uses no power at all). As a bonus, these methods don't require killing all your programs and starting them again, so you can resume exactly where you left off (even, for example, resume an interrupted download in most cases).
Disabling Fast Boot (look up how to do it, I'm not going to bother holding your hand all the way to the search box of your browser) would let you power the machine down more quickly, but will make bootup somewhat slower (though Win8 still boots up quickly). Disabling Hibernate will also disable Fast Boot, but I don't recommend disabling Hibernate unless you're seriously short on disk space (it reserves a "hibernation file" that is the size of your system RAM). In any case, it's probably just fine to move your computer while it finishes "shutting down" anyhow, though; no need to wait until all the lights are off (don't bang it against anything while the drive is spinning, assuming it's not using an SSD, but that's never a good idea anyhow).
As for leaving WiFi on while the screen is closed, the most likely only way to do that is to modify the Windows power settings to select Lid Close Action: Do Nothing (it will still turn off the screen, which will save a bit of power). However, this just leaves the computer running and will drain the battery almost as fast as using it. A few Win8 machines have a special low-power mode called "Connected Standby", which is similar to what smartphones and tablets do when in sleep mode, using more power than a full suspend-to-RAM but turning off almost everything else except the radios. If your computer doesn't already do this while in sleep mode, though, you're probably not going to be able to enable it; I believe it requires hardware support.
WiFi turning off when you close the lid is normal. Closing the lid *under default settings* puts the laptop into sleep mode. Sleep mode disables WiFi unless your device supports connected standby, which yours doesn't to my knowledge.
Advanced power plan settings will let you set it so that closing the lid does nothing. I would recommend creating a new plan if you want to do that.
Pausing downloads is exactly why I prefer torrents when available, sadly few downloads are available as torrents
torrents pause when you get disconected?
torrents break up downloads into much much smaller segments (few kb to 1mb max) and download each segment independantly. Lets say a 5mb file gets broken up into 10 half mb files instead. The torrent client will download them individually, if the internet gets cut midway through file 4, when you reconnect to the internet it still has files 1, 2 and 3 so still has 30% of the progress already. It can just continue from file 4. So yeah, torrents can survive internet disconnection, sleep, hibernate and even a complete system reboot (literally, shut down the machine, start it up 5 or 6 days later and you will be almost exactly where you left off). At the most you might be 1mb behind but as torrented files are sometimes a gb or more that is pretty insignificant. And even on a dial up connection 1 mb is not going to take long to restore.
For smaller downloads like a single MP3 track or a word document its not worth it. But I personally have an internet connection running at 100-200 kilobits per second, so if I want to download a 1.5gb linux distro the ability to pause the download is a huge benefit.
Sadly, few downloads are available as torrents, they are also peer to peer so that relies on a peer being available (basically rather than downloading the file from a dedicated server I am downloading various parts from different people who also have a torrent client and the same file).
Too many people also associate torrents with piracy. It is true that you can pirate movies via a torrent yes, but that doesnt make torrents illegal in any way. It is common for very large files to be offered as a torrent purely because of the pause/resume functionality. Most major linux distributions offer a torrent as a major distribution method.
My preferred torrent client is bit-torrent, heard a few recommendations for μTorrent.
Back ontopic.
Done a little more research. Pretty sure now that your system will not have Connected Standby so you are stuck with wifi turning off when you enter sleep mode. Chances are if you had it then it would already be enabled.
Not really sure whats happening with the lights. In order on the laptops I have had access too (including my old inspiron) on shutdown the display would shutdown, then the fan would cut off and the lights would go out and that would all be within 2 or 3 seconds start to finish (usually the display > fan transition was longer than fan > lights). Never seen 3 minutes myself but I doubt the battery drain from it would be significant so I would perhaps ignore it as an odd quirk, perhaps keep an eye on it.
Yeah idk about lights staying on that long because I'm pretty technology savy and we have a 2011 inspiron that manily my syblings use and it dosebt have that problem but I guessing I'll just keep an eye on it but does anyone know of any hacks to keep Wi-Fi on.
Sent from my SGH-T759 and if my gramor is wrong it's probably because I sent this while walking or rushing before a class starts
The wifi on thing is hardware. The system almost completely shuts down in sleep mode. It keeps a little bit on to keep the RAM active and a few other minor tasks but for all intents and purposes its completely shut down. Only if your device supports Connected Standby can it enter sleep mode and keep wifi on. But at the moment only intel clovertrail chips support it. I think the haswell may be getting it too.
There wont be anything like a registry hack to keep wifi on. Wifi off in sleep mode is a trait of all major desktop systems. The only major operating systems which do leave it on are probably android and iOS and they are movile systems which never go into a true sleep mode. They just dim the display and prevent user applications from being run (unless they are given explicit permission to run when locked).
If you really want wifi on when your lid is shut. Go into the power plan settings, create a new plan. Go into its advanced settings and there is a section about what action should be executed for various things like pressing the power button, sleep button (if applicable), reset button (if applicable) and closing or opening the lid of a laptop etc. By default close lid will trigger sleep mode. You can hit the dropdown box and set it to do nothing. Even when set to do nothing, when you close the lid the display will turn off. But otherwise the laptop will remain fully powered on, infact if you hook up an external keyboard, mouse and monitor the system is still usable. The battery drain will be almost the same as leaving your system idle for ages, but as the laptop wont be in sleep mode the wifi will remain on. Its worth looking through that menu anyway, I personally rebind the power button to enter hibernate
maybe the “fast boot” i

I hate being the noob here, but fast boot does really restart system when shutting down?
I thought that it starts to shut down just like when not using it, but when only the kernel and drivers are still running, it hibernates those instead of a complete shutdown. This would make the black screen appearing after the 'Shutting down' message clear, as it is used when hibernating the system.

It shuts down, rebooys and immediately hibernates. Then when you go to hit the power button to turn the system on it appears to boot ridiculously quickly because it only has to wake from hibernation. This might indeed cause the lights to stay on a little longer

Is this really happen after Windows 7? I didn't restart my laptop and only use sleep mode since upgrade to Windows 7. I only shutdown or restart when Windows Update (sometime I force to not restart), software install, hardware fix.

What did you mean hybrid-shutdown? And what you did when you full shutdown/reboot?
I'm not experiencing the same issue on windows 8 myself
Hybrid Boot (that's the correct name for hybrid shutdown / fast boot) does not fully shutdown computer. The process is divided into two parts: log off all users and hibernate remaining system/kernel part. So if you have misbehaving drivers/services, then computer can become unreliable after some time.
When you restart computer, even with fast boot enabled, system goes to full shutdown without hibernation part, so this can temporarily resolve problems like above.

A quick google on the issue brings this up
Windows 8 changes this by shutting down as far as closing the user sessions. At that point, instead of continuing and ending system services, and shutting down
Session 0, Windows then hibernates. This is called Hybrid Shutdown. The steps are shown below.
Click Shut down.
Windows broadcasts messages to running applications, giving them a chance to save data
and settings. Applications can also request a little extra time to finish what
they’re doing.
Windows closes the user sessions for each logged-on user.
Hibernate the Windows session.
Essentially a Windows 8 shutdown consists of logging off all users and then hibernating.
http://blogs.msdn.com/b/olivnie/archive/2012/12/14/windows-8-fast-boot.aspx
A full reboot of windows 8 takes a lot more time than the hybrid shut down. When you reboot, the actual shut down procedure of windows 8 occurs, without cutting off power, ofc.
Therefore, hybrid shut down aka fast boot has nothing to do with restarts.

Maybe this shows that I am a noob, but here it goes.
I want to save my battary power when running the GPS, but all the power saveing settings turn the phone onto standby, thus loosing GPS lock (and when I am using my better bluetooth GPS, it locks out the bluetooth and I have to re-boot). Is there some why to just turn of the screen? Is that "an app for that"? I am currently trying out SVM Power Manager, but you can not set it to turn the screen off in 2 minites or whatever. To use it how I need, I would have to turn off the OS's power saver, and always manualy turn off the screen using SVM Power Manager. All the power manager apps I have seen work like that.
Help!
you will probably have to buy an extended battery man. i think even real android phones batteries drain pretty quick from what i hear.
Did some testing. It seems that the battery will last for about 5h with the screen of (using SVM Power Manager to turn it off), and the GPS running (GPSed running it).
Understood that the battery is just under powered, but I was wondering if there was a way to make the screen automaticaly turn off after X amount of time, but not have the phone go into standby.
I also bought one of those battery powered battery chargers (battery extender). But the one I got turned out to have only 500mAh (compared with 1100mAh in the phone battery), so it turned out to only help a bit. Maybe I will try to make one with a voltage regulator and a rechargable 9V battery
I think one of the pmsleepmodes may support this (in default.txt) Try 2 or 3. It seems like one of these didnt do a full power collapse, but did turn the screen off.
katmandu421: I am not familiar with this stuff. Can you give me a bit of a more detailed explination?
Is this a built in windows mobile funciton. Can I access this in the registry?
I love it how most of us would assume he's talking Android. Yes in android, editing your default.txt to sleep mode 0 would turn off the screen, but not sleep the system. 1,2, or 3 would allow the different system board types used in various Vogues to go to sleep.
WinMo however is a different story. The GPS in the Vogue is a low power chip, but from everything I can gather is requires the system to stay fully awake. If you find an app that allows you to turn off your screen, post back but I don't believe there is much hope to that. Windows seems to think that when the lights go out, it's sleepy time.
Also, the radio on the Vogue doesn't sleep, and it's use to wake up the phone i.e. incoming calls. The GPS is part of the radio so if there is a way to keep the system board awake, in theory it should work.
SVM Power Manager will turn off the screen while keeping everything awake, but it is not automatic. I have maped the camera button to this program, so it is not a huge hassle, but I realy would like to have it automatic.
Will consider installing Android.

Thanks! That looks like a handy app.
An update (in case anyone hits this thread later)...I made this one change which seemed to clear up all of the problems (found elsewhere but can't post outside link yet.)
[HKEY_LOCAL_MACHINE\Comm\ConnMgr\Providers\{7C4B7A3 8-5FF7-4bc1-80F6-5DA7870BB1AA}\Connections\Phone as Modem]
"Enabled"=dword:00000000"
Now this is in conjunction with QuickGPS and all the other fiddling I've done, so I don't if this alone is responsible.
However, when running Google Maps or other GPS applications I get a lock within 5-15 secs. Also, when coming back from standby it's able to re-lock in the same amount of time. This normally required a soft restart before.
For apps that track your routes, such as SportyPal which I've been using for mapping my bike rides, they can keep a lock even in standby mode. I'm not sure if the app itself is able to hold a lock or if QuickGPS may be helping it. Either way it works.
Hi All,
in the company I work for we use a range of XDA's for our drivers, the current and most popular one is the HD2, however i have noticed that drivers are able to put the XDA to standby, normally this is a requirement, however for the system we are using it causes major issues and provides the driver a way to cheat the system.
What im looking for it a way to disable the hardware buttons when the device is switched on, i imagine there may be a registry edit, but im not sure and need help as this is becoming a pressing issue.
Thanks
M
Your request is very peculiar, and I seriously doubt that you can achieve something like that, after all completely disabling the hardware buttons can impair seriously the functionality of the device and I don't think there is a pre-set method to do that.
Anyway, I've seen a thread that talked about reassigning the shortpress on power button to something else (and I'm talking about shortpress, not longpress), yet this didn't work on the HD2 when I tested it this morning.
Anyway, if your system is debunked by putting the device in standby, it will also troubled by simply removing the battery. In other words, you can put a strong password to forbid a user from turnning off a pc from the start menu, but you cannot forbid this user from pulling the plug off the mains
Anyway, a very feeble solution could be making so that whatever is that's thrown off by the standby, keeps working even in standby; there's a tweak for wifi that allows wifi radio to stay on during standby, and probably forcing the wifi always on, and tweaking it from bsb to be on even during standby, it will also force the CPU of the device to be on even if you lock the phone by press endkey
Dont really want to give too much away, but our application uses gprs/3g and gps constantly, and by going into standby it loses connection with our servers and gps, thus allowing users to go standby in one area and then turn back on somewhere else but system thinks they are in area 1 until they move to antoher area again. this causes a major issue and headache for me, so what i really need is for the app to remain live when in standby and to keep the data and gps connection live
hope that makes sense

Normaly the numbers are on "4" - put this on "1" and gps should stay awake even when you put the phone in standby.
It will stay on until a program stops using the gps.

It's the first one you should try. Works fine for me.
http://forum.xda-developers.com/showpost.php?p=6416870&postcount=6
But frankly if they do it on purpose they will no doubt find other ways to do it - so you should rather build in some protection in your software to detect it, like if 2 consecutive positions are at the same place but with more than a certain amount of time apart, it's that they turned the thing off / cut connection on purpose/...
EDIT: wilcovh beat me to it.
those reg edits have been confirmed not to work... at the time being there is no way to have the GPS stay on while in standby, and that's a pity. I am personally interested in this and have researched in the forums, yet no working method was devised (yet). And I would love to be corrected by someone, but all the solutions I found were app specific (as in, app turns off screen without turning off GPS).
So, unless the drivers should have a personal reason to "cheat" the system by turning off the GPS, just instruct them not to press that button
If they just want to turn off the display, you can make it so that they do just that without actually locking the device, by associating, as I did, longpress on send key, with xdashutdown /lightsout command. That will turn off the screen but the phne won't be locked nor put to standby.
the theory of having gps active while on standby is moot and now useless, i need to stop the device going into standby mode period
to my best knowledge you can't really do that; I mean, you can programmatically disable automatica standby in an app by calling a function to reset the idle timer, yet the power button will put the device into standby.
I'm almost positive neither AEbutton plus can remap the power button short press on the HD2, but giving it a try won't hurt that much

But that's solved already!
The keepAwake app posted earlier, music players keeping playing when pressing the off button, IM clients continue to run and receive messages after pressing the power button (implies both processor running and internet connection active)... in these cases, like any app that does the required system calls to disable standby while it's running, the device won't go to standby.
The only real problem you're facing is that GPS goes off when the power button is pressed, regardless of whether the rest of the device actually goes to standby or not (try running a GPS app while playing music, press power button, music still plays but GPS turns off).
Now we pointed some hints for you - you can try them (the reg edits for GPS apparently work in some cases but not all), but if they don't work then you're alone on that one, no solution is known. And tbh I've never seen any device on which you can disable the power off key, and it's obvious why...
so after a couple of months of reading reviews and post by owners, i decided to pull the trigger last night.
after a 3-4 hour charge, i jumped right into it.
+very fast boot up.
i played with Honeycomb 3.0 before updating it to 3.1. i noticed that 3.1 had bootup & keyboard sounds, while 3.0 had none.
+the chassis is really nice. i loved the look. reminds me of my HTC HD2. rock solid.
+YouTube plays nice. i can already tell that i'm gonna be using this for mainly YouTube. but it really sucks that some videos won't play because it considers the A500 a "mobile device".
+web browsing is good so far. it even ran southparkstudios.com
uhm...that's all i can think of right now for pluses...
...and here's my cons with the tablet:
-it loses wireless connection when the screen goes to "sleep". but this apparently is a VERY common bug and issue with A500 owners. very annoying that i have to restart the wireless to get connection back. this is the main issue i have with it so far. my phone doesn't lose connection to the internet with the screen goes to "sleep".
-there's a dead pixel, but that's easily fixed by exchanging it for a new unit.
-lots of my games that i would normally use on my phone are completely useless because it still maintains a phone sized image. OR it just force closes.
-No Netflix app. although i read somewhere on the internet that there's supposed to be an official Netflix app coming out. but there's no way to confirm the validity of that statement.
-No Hulu
-No dedicated Facebook App
i still have lots to try out still like the HDMI out, the functionality of the USB ports, Divx/MPG/Avi compatibility, and MP3 sound quality. plus i want to see if i can install an NES/SNES emulator and play it via a bluetooth gamepad.
i noticed there's LOTS of ports...which means more possibly entry points for dust. which can be bad. ACER (or someone else) should make plastic/rubber port bootcovers to remedy that.
i haven't tried to install a custom ROM. nor have i tried to root it.
i'm looking forward to the 3.2 update. i'm hoping that'll fix all (or at least some) of the cons.
As for the internet connection, mine with stock rooted US rom (.13) doesn't do that. I have always internet after sleeping.
For the phone apps no scaling you can use Spare Parts and uncheck the compatibility box.
Facebook you can side load it, it works nice on my tablet.
Hulu is a common problem with all the tablets, you need a fixed flashplayer apk.
Hope it helps you
Root the device, for now try virtuous Xoom with 3.2 honeycomb. Once rooted netflix is fairly easily installed. Also, you can set the browser as "desktop". Mine has never lost wifi for any reason other than range.
My a500 have never lost WiFi during sleep.
There is a Tablet app "Friend Me" for Facebook and it is very good!
"Spare Parts" with "compatibility mode" disabled will make all apps full screen!
Never had a problem with a game (except those made or specific hardware)
Hulu and Netflics I can't comment! Living in Europe!

yikes i almost forgot about netflix
Netflix works great on the a500 - you need to root via Iconiaroot (assuming you are using 3.1) and then simply follow the instructions located here - http://forum.xda-developers.com/showthread.php?t=1076150
Just follow the instructions - either use root explorer with system mounted r/w or snag Acer recovery installer from market, install cwm, apply the patch.zip and you are done. Netflix looks great on a 10.1
hmm... seems like the consensus is that everyone doesn't have that issue. maybe my situation was a one time only thing.
but let me explain to you what i was doing when it happened:
i got tired of the Market app on the A500. but i'm also tired of the Market app on my HD2 as well. the new updated Market doesn't show you everything, it just shows you like the top ten for every category. anyways... so i put the tablet down (i didn't turn it off or put it in stand-by) and sat in front of my desktop and used the web browser version of Market. i probably spent about 15 minutes or so sending apps to install onto my device. when i went back to check on the tablet, the screen was off. i pressed the power button to bring the screen back on and the Wi-Fi was showing that it was 'OFF'. the only way to bring it back was to restart the Wi-Fi.
so yeah... it was strange. but like i said, maybe it was a one time event.
maybe i'll just set the timeout for higher like 60 mins.

Nope.
You issue is a result of your settings. If you want your a500 to keep a active wifi connection while the screen is sleeping, you will need to go into your settings menu and tell your a500 to not drop the connection while the screen is off.
ahhh... cool. i'll definitely be playing with the settings tonight then. thanks.
Wifi is my only complaint so far and I am experiencing the same thing. Mine is set to never disconnect wifi, and it doesn't. It shows wifi connected the whole day under battery usage. However, when the screen goes off it seems to drop the wifi and I must disconnect/reconnect to get it working again when I turn it on. Not every time but it is frequent.
To be clear:
When I turn the screen on, wifi is unusable until I go into settings and toggle it off and back on.

Are your wifi settings -> wifi disconnect settings set to not drop the connection when screen is off? Screen set to never sleep will not keep a inactive wifi connection alive - you need to go into wifi and networks catagory of settings and modify the disconnect policy.
Yes I know, sorry I meant never disconnect wifi not sleep.

I am confused.
Are you saying you have wifi disconnect policy set to "Never disconnect", but are having issues holding a wifi connection after turning the screen off?
Please provide more information, very hard to troubleshoot something this vague.
There is a difference between WiFi turning off and WiFi disconnecting.
Here is what I'm seeing on mine:
1) With my tab on, WiFi connected, browser working, I can ping my tab from my desktop.
2) Shut down browser, put tab to sleep, wait an unknown timeframe (lets say 15 minutes).
3) Wake tab, see WiFi is still connected, do nothing else. Start pings from desktop in a continuious loop, pings all fail, despite WiFi connected on tab.
4) Start browser on tab, browser connects to test website, and suddenly pings respond on desktop.
So, it appears that while the WiFi on the tab stays connected, it does not actually go 'active' and start handling data until an app needs it, such as the browser.

3) Wake tab, see WiFi is still connected, do nothing else. Start pings from desktop in a continuious loop, pings all fail, despite WiFi connected on tab.
4) Start browser on tab, browser connects to test website, and suddenly pings respond on desktop.
So, it appears that while the WiFi on the tab stays connected, it does not actually go 'active' and start handling data until an app needs it, such as the browser.

No shortage of apps that can work around this - I don't understand why you want a network connection when nothing is using it, but to each their own

The wifi issue you describe is not a bug. It is an android feature to reduce battery drain. If an app or connection is not in use, it is cached until a process is called.then the wifi connection becomes active. You can disable wifi sleep policy but you will see a battery drain if you set it that way.
Remember the two most important parts of a tablet are the screen and the battery. A poor screen or poor battery life will kill sales for that tab faster than apple can draw up a lawsuit.

Well described.
Not sure why a user would want to bypass this - the moment an app requests data, as long as wifi disco policy is set - network connection is set to active.

Untrue. I have used a number of applications that when launched, do not 'activate' the connected WiFi. Two for example, 'QuickSSHd', which is a SFTP and SSH server, and 'IP Webcam' a webcam server.
Wake up the Tablet, and see that the WiFi shows a connection. Fire up either of these server applications, and try to connect to them. No go...
Now go fire up the browser, which of course makes an 'outbound' connection, the WiFi 'activates' at that time, and suddenly both of the aforementioned server applications can be connected to.
In other words, when the 'conected' WiFi is asleep, it takes an 'outbound' app to wake up the wifi. An app that is waiting for an incoming connection never sees one until an outbound app wakes up the wifi.
NOTE: This behavior is NOT seen on my Android Gingerbread phone, running the same apps with the same sleep settings.

+YouTube plays nice. i can already tell that i'm gonna be using this for mainly YouTube. but it really sucks that some videos won't play because it considers the A500 a "mobile device".

It is not the video seeing the tablet as a mobile device.
It is your settings.
You can fix it very easily.
2 things to do.
open your browser
in the URL window (address bar) type about:debug and hit enter
it seems nothing happens but it adds a debug in settings
Next
On the very top right click the 4 lines with an arrow.
Click settings and on the left side click "advanced"
click "Viewing Mode" and set it to "desktop.
Now on the left click debug
click UAString and click desktop.
That's it.
Make sure you haven't saved any bookmarks from the mobile sites or they will still open from the bookmark as mobile sites.
Hi, I have Windows 8 Pro 64 bit on a Toshiba Portege R830 (Core i5) laptop.
My problem is that if I lock the screen and shut the laptop lid and leave it for a while, when I reopen the lid the screen is all green but otherwise completely blank apart from the mouse pointer (which does respond to the mouse/touchpad ok), and there's no way to unlock the screen to get the system working again that I can find. I have to long-press the hard power button to force a power off, then re-boot from cold. Everything works after that until the next time!
I do have a screen saver enabled (Electric Sheep), but after a few restarts the screensaver is disabled too. Also I have the power profile set up to do nothing on shutting the lid (i.e. no standby or power down) when plugged in to the power.
Does anyone have ideas how to resolve this? I figure that whatever's disabling the screensaver is also causing this behaviour, but I could be wrong too.
TIA
Has this problem recently bugged you or was It present since when you installed windows 8?
I'd say it's been on and off since Windows 8 was installed (RTM Box version, clean install -i.e disk-reformat). When I re-enable the screensaver it seems to behave for a while, but then when the problem reoccurs, the screensaver also seems to gets disabled (which I never do myself).
Sounds like hibernate or standby isn't working on your system. Check for a firmware update. Try disabling hibernate. You'd also lose fast boot, since it's tied to hib.
Hibernate disable: Win-X, run Command Prompt Admin. Enter powercfg /h off
Check available sleep states: powercfg /a
Also, try powercfg /energy for an energy diagnostic.
Portege R830 BIOS version 3.90_160 - 2012-09-12
* EC/KBC V1.60: Improved standby stability.
* EC/KBC V1.60: Modified the power supply error detection method.
>I have the power profile set up to do nothing on shutting the lid
Lid-close action is separate from inactivity. System will still go into standby or hib unless specifically disabled.
I have a laptop pretty similar to yours. I have the portege r835-p56x
I have had this problem but did you check event viewer. I know that some if the drivers will cause certain problems.
The only problem i have is if I leave my computer for awhile, it locks itself and I don't even have it set on that setting.
To add extra info about my setup in regard to your problem, I don't have the screen saver enabled but I have hibernate enabled.

There are two things you can do with the lock screen - you can prevent it from appearing on startup with a group policy change and you can prevent it from locking the system automatically after 1 min (this is the windows default)
To prevent the lock screen from appearing at startup:
press Windows+R (the Run command) and type GPEDIT.MSC
navigate to Computer Configuraton\Control Panel\Personalization
Look at the setting for "Do not display the lock screen" and set it to your preference. It takes effect on the next reboot.
To prevent the Lock Screen from locking the screen after 1 minute of inactivity there's a hidden power setting for the Display you can change in the registry. See this post on the Windows Eightforums: http://www.eightforums.com/tutorial...ole-lock-display-off-timeout-windows-8-a.html

I found a simpler way. Might not work for you, but, my little sister had the problem. So we looked on every website we could find. I finally gave up, then had the idea to restart the computer using the restart button instead of force shut down. Guess what. It worked...
I have a stock unrooted Verizon Galaxy S5. For several months my phone has been plagued by several issues at startup. Whether I reboot the phone or start it up after the battery has died, it always enters an odd state immediately after loading and seems to get stuck in this state for an undetermined and variable amount of time (anywhere from a few seconds or minutes to hours or even overnight).
While in this state, this is what happens:
1. Screen stays on. Once I unlock the phone, the screen stays on. The side button doesn't do anything to lock the phone or turn off the screen. Holding down the button, however, still triggers the power menu. The screen timeout never triggers, even though it should turn off the screen after 2 minutes of inactivity.
2. WiFi and Bluetooth turned off. Even if they were turned on before I powered down the phone, they are not enabled when the phone first boots up. I can manually turn them on but the WiFi will not connect to a network, even if one is available. It may show it is connecting to the network, but it gets stuck at "Checking the quality of your internet connection" and continues to use the 4G network for data connectivity. This happens no matter what WiFi network I am within range of, so it's not an issue with the network or router itself. If I am not near a network at all I will still experience the other problems of not being able to lock the phone, etc.
3. Startup applications don't load. I have Tasker on my phone, but it doesn't load and show it's notification bar icon.
Otherwise, I can use the phone normally and open applications, surf the web, etc. It seems that loading some applications and using the phone eventually causes the phone to exit this mode, but I haven't been able to find a single particular application or series of steps to fix the problem. If I power on the phone and don't use it that just seems to make it take even longer to fix itself.
Once it gets out of it's weird state, the WiFi connection will become active (it will turn on WiFi if I haven't done so manually already) and it will connect to a known network if one is available, the phone will lock itself or I can do so from the side button, and things like Tasker and Power Save mode will turn on.
I am stumped as to what could be causing this problem or how to fix it. It seems the phone may be doing some kind of check, maybe related to Knox, that hangs during startup and prevents certain things from working until it straightens itself out.
Any clues into what this problem is, what is causing it or how I could further analyze this problem and determine its cause would be greatly appreciated.
Never heard of or experienced these issues. May want to contact Samsung.
Have you installed any official updates from Verizon at any point? I've heard of phones having phantom problems like this after receiving a bad update. I would definitely contact Verizon if you did update at any point. If not then like BigBot96 said, contact Samsung about the problem.
My wife's Note 2 did something similar when the battery died. I had to factory reset. Her phone was rooted/unlocked & running a custom TW ROM, though. May I suggest doing a complete factory reset and Odin. Backup data to computer or external sdcard since this will clear the entire device.
Edit: After rereading OP's post it actually sounds like an app is hanging at startup which could cause this behavior. A logcat should tell you what's going on.
