Nook should boot almost instantly

I can understand a PC takes a while to boot considering how many different devices it has to set up, but... a nook? It is so simple it should take less than a second to boot.
Any one knows where is most of the time spent during boot?
Thanks

What Linux powered devices do you own that boots a cold, non-hibernated, system in less than a second?
In fact the boot sequence on the NST, or any other Android device for that matter, is more or less the same as on a PC, and the device count ain't that different.
The kernel still have to load storage, input, graphics, networking, usb and whatnot.
Hell, one second isn't even enough to finish the bootloader stage

Considering it is a flavor of Linux, probably running those never ending screens of things being started up. As the nook should be an optimized version, it should really go faster. But an unrooted version goes faster than a rooted one, that was one thing I noticed. Maybe running extra services and start up apps.

Well, it's running a Linux kernel and the kernel has to load like any other kernel
There's no console output to fb on boot, and even if there was it wouldn't make a dent in the start-up time.

Faster than what? A PC with 6 - 36 times the processing power?
In fact, the NST kernel loads faster on its puny 800MHz single-core ARM than the 3.0.0-13 kernel on my quad core 2.6GHz AMD.
What we don't see behind that nice boot animation screen is the system that's being loaded on top of the kernel, namely Android and it's Dalvik virtual machine.
If you go trough the logs you'll see that this is where a large portion of the start-up time is being spent

Well simply rooting the NST enables a single tiny service (adbd) and there's no difference in start-up time booting with the stock ramdisk or the adbd enabled one.
I just tested this for the fun of it, and the start-up times are random variations in the order of milliseconds
Now, like you point out, most rooted devices aren't just rooted but have additional services and apps running, and naturally that increased workload would make the device run a little slower based on the amount of additional stuff, and the quality of it

Nice and complete answer, Roger.
Thanks for taking your time to answer that. Maybe the startup time of an unrooted nook was clearly due to extra overhead apps and services. It is quite noticeable, as I did the restore/reset/update/root/restart after fail several times.
Dalvik is the JVM on the android?

3 seconds from you press the power button on your pc? Care to share a video of that?
My pc uses 10-12 seconds just to get to the bootloader menu..
Now, aside from that, I've already stated that a large part of the ~30s boot time is spent on loading Android, there's not much that can be done about that.

[Q] Windows 8 overheating my ultrabook

Strange little problem I’ve got here. I’m using the brilliant Asus UX31E ultrabook which is a 1.8ghz i7.
Didn’t have any problems running windows 7, but just installed a fresh windows 8 last week.
I’ve installed all the updates I could find from the ASUS website but here’s the problem, with windows 7 the fans would only ever come on if you were really pushing it playing a game. Using windows 8 the fans will regularly come on just browsing in chrome.
when you open task manager the computer details recognise that it’s only a 1.8 processer yet it often is being utilized as high as 2.8ghz! This is making the machine overheat, turn on the fans and sometimes have to turn itself off.
I’ve been into power settings and reduced the maximum power usage to 70% and that usually does the job, but then it quickly forgets this setting and restores it to 100% (2.7GHZ!). In task manager the highest task utilisation wise is ‘system’ but no idea exactly what it’s doing..
Is there anything I can do to have greater control over the processor speed or investigate what might be causing the problem?
Asus had some power control software for windows 7 but don’t seem to offer it for windows 8.
Cheers guys

Have you done a upgrade or clean installation from windows 8
if you had done a upgrade please do a clean installation of windows 8
if not then go to the advance power settings in the control panel and set processor cooling state to active

I was wondering if it was a true clean install or upgrade. I read he installed a fresh copy nut wasn't sure if that was meaning clean (wiped the drive) or what. I didn't really notice.alot of heat issues with my last laptop I upgraded; I chose to keep personal files and settings. I do have about 180gb of pictures and movies which were scattered in multiple locations on win7. Now my media is very orderly, as well as my 20gb of music.
Saying all that, I believe when I installed the media center that it cleaned up my files, or it may have just been windows 8, but either way it took some work on wimdows8 to organize my hard drive much better than before. I have scanned my hd for the need to defrag it, but it shows to be dang near perfect. If you have alot of media on your machine I wonder if its doing file management, which is making it run hot, etc. I know phones are different but when I load a new ROM it takes it several hours to slow down the media system usage.
How many days have you been running the system with wimdows8 ? Do you have a lot of Files/media on your machine ?

The majority of the time, the issue isn't with the Operating System as much as it is with a single application. Check task manager while your computer is running and see what applications are causing the processor to go nuts. If it is indeed a system application, then I would suggest doing a complete wipe and fresh install of Windows 8. You can back up your authentication key by saving a specific folder in the File Browser. Do a search on MyDigitalLife for that information.
Doing a quick search on your Processor, it runs standard at 1.8 ghz, and the 2.9 jump is completely normal. It's a feature called "Turbo Speed". With Windows 8 came upgraded drivers, which probably enabled this feature that you've never noticed.

[HOWTO] How to speed up Windows 8 Boot time

In this guide I will show you how to speed up Windows 8 Boot time, disabling unnecessary applications
Whats need
-Ccleaner latest version
-PC with Windows 8 :fingers-crossed:
Step 1
-run the program RUN.exe and then we write MSCONFIG and Enter
Step 2
-On the program go to the Services and click Hide all Microsoft services, now stopped some services that not need example: AMD, Google update, Hamachi, utility from manufacturer,Skype updater
Step 3
-Now go to Task Manager, go to startup and disable the unnecessary apps example:Utorrent, apps from manufacturer, Skype, Java
Step 4
-Go to Ccleaner, click Tools and go to Startup and disable apps from Windows-unnecessary, IE-all, Contex menu-all,Scheduled Task.all
Step 5
-Restart the PC and after off and on PC

I find it rather impossible to believe that your windows 8 pc took a whopping 38 seconds to boot.....I may be wrong but I believe that Windows's new system of hibernating the kernel session drastically reduces the boot time to less than 12 seconds.,,38 seconds and 8 seconds sounds like the difference between a windows 7 and windows 8 boot times rather than 2 windows 8 boot times.

I really booted 38-45 seconds because the application is very delayed, but sometimes I booted 8-13 seconds

Yeah... your 38 seconds was a cold boot, your 8 seconds was a hibernation boot. In any case, disabling services and the like doesn't really impact the boot time at all. It may change how long after login before the system becomes responsive, and it can definitely change how much system resources are being used in the background, but the only software ways to reduce the boot time (short of something like hibernation boot) would require removing drivers (as each one of those takes a brief moment to initialize) or using bootloader settings (and most of those are more likely to slow boot times down than speed them up).

Exactly.So the name of the guide should be changed to how to impact login times

well even on hibernation boot I need around 30 seconds (but 10 seconds of that contributes to my old BIOS) lol

My new record: 13 seconds. Cold boot. Doesn't get much better than that

Even a layman would know that disabling startup applications can speed up boot time.

Except they don't... Startup apps don't run until the system is already booted, so by definition they cannot impact boot time. On I/O constrained or single-core systems, they make the system essentially unresponsive for some time after bootup, but for something like the Surface RT (4 cores, Flash storage so very wide IO bandwidth) their impact will be minimal.

Hi guys,
I had a question.. My windows 8 used to boot really fast at the beginning on my PC.. But now its taking time.. Almost as much as windows 7 used to take, even during shutdown.. I've actually disabled hibernation function using tune up utilities.. Would this effect booting speed?

Disabling Hibernation will not speed up your boot time - quite the opposite, in fact (Win8 likes to do a "hibernation shutdown" where it restarts the computer then immediately enters hibernate, which makes the subsequent bootup very fast). It will have no impact at all on restart time, either (at least, nothing meaningful - possibly a few milliseconds at worst). Hibernate shutdown does indeed take longer (substantially so), but why do you care?

Chromebook better than a PC?

Hi there.
I'm doing this thread to once & for all find the ultimate answers to my PC "issues".
Before i bought my Lenovo Yoga 8 laptop i was thinking of buying a Google Chromebook. Specs might not be as high-end as a Windows PC but it loads a lot faster (having no such apps or enough background process to load in the background), apps load a lot faster, updates come automatically (and no need to download/intall like a PC), straighforward OS and no complicated hundreds of settings to tinker with unlike a PC. And besides a Chromebook is virus and malware-free forever.
I also happen to come from a Macbook Air and i found my PC that slow. Downloading & installing apps takes a lot longer, opening or closing an app or browser or tasks also takes longer. But in the course i have made some research to improve the speed & performanc of my Windows laptop mainly:
1. Turned off bluetooth
2. Set Windows Update to automatic
3. Updated Windows Defender
4. Defrafgging my gard drive monthly
5. Choose Selective Startup (under msconfig) and made sure no apps are enabled under Startup, selected apps are running under Services, choose a higher number under Processors and maximum memory set to at least half of what my Lenovo is capable of (under Boot)
6. Set performance to High Performance. (And being plugged in the mains)
What else have i missed?
Also i noticed when i look at Task Manager there are background processes that i do not understand and i'm not sure whether to disable them or not although it shows 0% affecting the RAM, etc.
If i don't get satisfied with this "complicated" WIndows 8.1 OS i might as well sell it and get a Chromebook as i use most of their services anyway on my Android phone.
To put things into certain context you see the most "intensve" task i will be doing in my computer will be downloading torrents 10 tabs/files at a time (it could be an .mp3 album or a standard .mp4 HD movie), wireless printing hundreds of pages from an assignmnt or work project, transferring hi-quality files (Flac or .mkv) to my Android tablet or doing an "intermediate-level" photo editing of my photos for upload to Twitter, Facebook, etc. My computer stays at home 99.99% of the time and IS online 100% of the time.
What you think guys?

I am not exactly sure what you bought, cause I can't find any Lenovo Yoga 8 running windows 8.
If you find windows 8 slow, you either bought something very low end, or something broken inside.
And no, a chrome book is not better than a PC. A PC has this thing called "reliability", which the chrome book lacks when you no longer have an internet connection.
Unless you are ready to pay a hefty monthly subscription to some mobile operator for unlimited data connection (which isn't really unlimited, after around 4GB, your connection will be slowed down automatically in many cases), and are ready to face the consequences of not having said data connection service whereever you go.
Even if windows PCs are more "expensive", which they are not, you can find a much more powerful computing machine at the same price of a chrome book (haswel i3s are really cheap now), you know you can do anything you want, whenever you want, and not relay on your internet connection to do more than checking the time.

Sorry...
I have bought Lenovo Yoga 2 11-inch Windows PC.
The MacBook Air I had before my Lenovo one stayed at home 100% of the time and is connected to the web 100% of the time. My fibre broadband is at least 70MB downloads speeds. With this respect a Chromebook would be suitable for me.
The PC I bought isn't low-end by any means. It is of the higher mid-range ones based on the specs itself. As I said I have done my own research, looked at Youtube videos on tip & tricks. The 8.1 update itself took me almost 5 hours even with that good specs. After that it is still slow. You can set up a Chromebook in 5-ish minutes, takes under 10 seconds to boot up from no power or sleep and apps start almost instantly. Because of probably all these background processes going on in Windows 8.1 it is still slow. Have shut and stopped some of them but still no significant change.
WIndows 8.1 isn't the lightweight, smooth OS I was hoping for. It is still "complicated" compared to a Mac and a Chromebook. Having it owned and used for 4 weeks I think that was enough for me to realise that perhaps....maybe next time.

Your PC is VERY low end. It has a Celeron/Pentium processor which is basically a higher clocked intel atom.
Upper mid range is core i3, not celeron my friend.
A MacBook has a core i5 processor, among other things, like a SSD for storage.
You traded a lot of mobility in the yoga for lower specs. This is why you paid so much. You can easily get a haswel i5 for this money, which is almost 10 times faster than this. You didn't research properly, I am affraid. This ain't no notebook for keeping around the house. this is a mobility oriented product.

Well, anyway i have returned the Yoga 2 back to the store and got myself an Acer C720 Chromebook. First impressions? Positive. Solid keyboard (could do with a backlit one), good sounding speakers, solid build quality and that's it so far. It's barely 24 hours so its too early to say as i haven't tried it that much yet.

IMO the best thing to improve general "feel" of a computer, especially things like how fast applications start up, is get an SSD. I don't what your Yoga had, but if it was one of the ones with the 5,400 rpm drives, it'll be slow.
If all you need is Chrome, then a Chromebook has the advantage being cheaper. Whilst a 10 second boot that Google claim for Chromebooks is quick, I wouldn't call Windows PCs slow, so long as you don't cripple them with a slow hard disk. My low end Asus T100 boots in 12 seconds (my Android Nexus 7 2013 takes 30 seconds). I don't see why web apps would load slower or things take longer to download on Chrome under Windows, than on a Chromebook - has this been tested (on equivalent hardware and network)?
"updates come automatically (and no need to download/intall like a PC)"
But you still have to download them on a Chromebook, and it happens automatically on Windows...
Never had a virus on Windows, and virus checking is built in and in the background now. There is more of a risk, but then it's like saying you're better off with a £10 dumb phone, because it's impossible to get a virus on it

Chromebook has everything you need? Then well, go ahead. Cause it is cheap and maybe simple to use.
Just make sure one day if you come up with something that you want to do but can be done only on a real computer (like using certain software or playing certain games), you can't. At the end of the day, you pay for what you get.

A Chromebook and a PC serve different purposes. A Chromebook is like a motorcycle, lightweight, efficient and it will get you to from point A to B on the internet. A PC is like a truck,it can do a lot more but needs a bit more hardware to run on. If you can get by with a Chromebook do ahead. But I want full desktop programs, hardware driver support, etc. Thats why I got a Toshiba Encore tablet that runs 8.1. Windows still feels kind of weird on a tablet, but having a full desktop OS in a device that portable is awesome and those Bay Trail Atoms are a hell of a lot better than previous Atoms.

The Lenovo Yoga laptop i got is a quad-core Haswell-powered computer. Yet, it took me 4 hours to update it to 8.1 whilst my Chromebook took 4 minutes (even less) to set-up. My quad-core Yoga took 30 seconds (or less) to startup whilst my Chromebook took 7-8 seconds maximum.
Since having an Android phone and tablet for the past 4-5 years i feel i am tied up to Google and its various services. I can still avail and enjoy some of the MS services like OneCloud and OneOffice via its web app versions so for me that's still ok.

According to Lenovo it was.

Windows 8/8.1/10 doesn't work with Switchable Graphics. Sign the petition!

Since Windows 8, First generation Intel users were unable to update our graphics drivers because they lead to bootloops, BSODs, screen/brightness glitches etc. Almost every 2010-2012+ Hewlett Packard user (and some MSi, Vaio and Toshiba Sattelites) is having this issue. Now that Windows 10 is released the situation still remains the same.
The problems:
BSOD while installing the drivers provided in Windows Update. When the OS installs the new driver, the screen starts flickering and then shows a Blue Screen of Death. After that, the PC never boots again (see below). Since W10 these updates are forced to auto-install everytime, so it's almost imposible to stop the laptop to get into that state.
Bootloop - Blackscreen after Windows bootlogo. After the BSOD, the laptop restarts itself after 5 seconds, and it never boots again. In some cases it leads to a blackscreen and then bang! BSOD again. In others, it just stays in a blackscreen with sound and the ability to control brightness and core functions like Wi-Fi network and Sound. In other words, the laptop works, but the screen doesn't.
After another "update" the laptop boots in Intel Mode only. Seems like the "workaround" for the problem by AMD/Microsoft was to disable AMD cards and force the device to run in Power Saving mode (Intel Card). If you force an app or game to run in AMD mode, it will lead to a blackscreen with sound and the only way to revert that is by rebooting the laptop.
Some apps still use Intel Graphics, even if they were forced to run ATI ones. This can be checked with DXDiag.exe, which displays Intel info in Video Graphics, even if the program was forced to use ATI. TL: DR: Apps don't recognize the ATI card.
HDMI Output doesn't work. Since ATI cards doesn't work, so does the HDMI output. There's no audio/vido in the external multimedia device.
Here's a link for the problem and all those affected users in Microsoft Community. A Microsoft Representative answered the first two pages, then dissapeared. Right now there're almost 40 pages about people claiming at least one response or a guarantee to get this fixed. This is not Windows XP, we still have more than 10 years of support.
I can't work because Microsoft and AMD don't support me, they don't support a one-year-old technology. I'm a Video Designer/Editor, I can't work with a power saving GPU. I (we) didn't bought a $700 laptop for a performance of a $250 one.
