HD2 won't sleep! - HD2 General

Hi, wonder if someone else has had this problem.
My HD 2 will only sleep when on mains power. If it on battery when I put into sleep with the on/off button it comes back on after 1.5 seconds. Same if you wait 30 secs for it to go into sleep. To fix it (temporary) I have to put it on the mains for about a minute and then it behaves itself until the battery is about 50% and then it won't sleep again. This obviously drains the battery.
I have 'hard reset' the device and it is still the same. I also updated the rom from Vodafone support site. Still can't fix it.
Can anybody out there help please, it's driving me mad!

I have this happen every so often. fixed by plugging into the usb cable (doesn'tneed to be plugged in). what I understand happens is in the usb port a connection gets wobbled and stops sleep. sometimes I have to plug it in and out a couple of times.

Thanks
Thanks, didn't try it without power. I'll just carry a mini usb connector with me! Thanks again.

that's what I've started doing.

The USB insert actually doesn't work
Hi, tried the fix suggested but it doesn't work for me. I have to have the power supply live to make a difference.
Any other ideas?

sometimes it can take a few attempts. I normally soft reset first to see if that fixed it first. other than that I don't know.
sorry!

mine's started doing this now.. yey! rinses the battery too while its stuck on.
Tried a hard reset, even a different ROM and hasn't fixed it.
I'll try a different radio next
Anyone else got any ideas? is there some software that can monitor inputs to see what it is that's waking it up?
Spike

^ different radio didn't fix

Hey.
I had this, but after a while it didn't only do it on mains.
It started to do it all the time, and as you can imagine that was killing the battery.
I tried everything! took everything back to exactly how I got it and it still did it.
so I took it in for repair, they sent it back to me and it had clearly been opened up, and the screen was brand new.
If yours is still under warenty, take it to get fixed.
I spent a little over a month looking fro a fix and nothing worked at all.

Last 3 days i also have this problem....
Anyone found what is causing it or sending it for repair is the only thing to do..

anyone please?...

Press a button .. fixed
Haha
Mine does this too all of the sudden.
There is a very, very easy fix for this...
press the right lower button (The hang-up button)
Battery life is extended from 1 day max to 2-3 days standby even!
It used to go to sleep automatically tho.
I think I probably 'tweaked' it with the tweaking tools and that's why
it does it. I'm too lazy to turn it off - and - to be honest - it's good if it's on all the time. At least my GPS won't just stop the readings I take all of the sudden.
And after I'm all done playing with Navigation, I can still press the little button.
(It really IS NOT that much of a problem to quickly press it)

You might want to install the S2U2 program, and let it manage your power settings. I've found it to be much steadier and more reliable, without those sudden wake-ups and battery draining issues.

I don't think it has anything to do with software.
It is clearly a hardware issue
I had the same problem. After inspecting the usb close, i found that there is some dirt and/or corrosion at the contacts.
I cleaned them up using some spray for electic contacts and problem has gone for almost 1 week now.
I read somewhere on XDA that an other member tryied the same thing, problem solved but came back after a while...
Anyway the fact that i cleaned the usb and the problem is gone for now shows that is clearly a problem with this part of the phone..

solved
i two have had this problem and have just found out how to sort it out. basically i tried everything new radio, rom, getting rid of CHT
and in the end all it was is the usb connection!!!!
all you have to do when unplugging your usb cable is make it come out on a angle left to right. there are obviously some very delicate contacts that get knocked out of kilter making the phone think its still on mains power when its not hence never turning off
you can confirm this error by unplugging your phone going into backlight settings and seeing if you can adjust you light setting on battery power if when you adjust your light setting nothing happens you got the same prob as me

Well, mine was fixed by a hard reset. Been testing it since, and it hasn't failed to go to sleep now.
Since there's a few different "fixes". might be a couple separate actual causes.

Started facing same problem when was on hols in +40 and quite humid atmosphere. Connecting cable helps but only if the cable is plugged in power socket or computer. And that is actually a problem as I do switch often between Android and WM and after restart HD2 doesn't go to sleep

Did this two months ago with good results ;-)

When I suffered from this problem a couple of months ago, I was flummoxed at first.
But then I decided to use a strong (20 diopter) magnifying glass to look at the ports and buttons of the phone. I could not imagine the amount of gunk I found inside the USB slot.
I cleaned with a very very small cotton swab dabbed in cleaning alcohol and wound around a pin and the problem was solved. Power consumption at rest went down from 30-40 to 4-9 mAh.
I now do this every few weeks.

I try the following, it works :

Tytn Won't Charge

I have noticed that for the last week my Tytn won't always charge itself up either when its in its cradle or is being charged via the charging lead.
I have no idea what has brought this on. The solution I am using at the moment is to soft boot, which seems to solve the problem for a while. For the techies on here I am using the standard HTC Win5 Rom, straight out the box.
Has anyone come across this problem and, if yes, knows what the solution is please? It was only because my low battery alarm kicked in the other day that I realised there was a problem.
As I use the kit for work I cannot afford to have it not charge up.
Many thanks in advance for your help.
WB
Caveat - Yes, did search first on here and elsewhere before posting.
Could be hardware (at Device) / could be software. Without testing these things out it's impossible to say. I suppose a quick test of the physical contacts of the device would be to switch on and connect the charger and by gently moving the connection, see if the amber charging LED goes on off.
In the end I always think with this kind of problem a hard reset saves a lot of time testing this and that. If there is nothing you can pin down as an obvious change/installation you made before this started, then I'd do a hard reset.
Of course you are fully prepared for this with full backups taken at key installation stages?? - Hope so.
Mike
The only thing I've heard of is that using USB cables/cradles, car chargers and non-standard wall chargers (such as for motorola) are ok for trickle charging but if the battery goes low you need to use the original wall charger supplied with the phone.
I know this was the problem on my Wizard - wouldn't charge a low battery with a motorola charger but fine with the original.
Mike,
I think I will do a hard reset as a last, last, resort only if all other options are well and truly exhausted. I rebuilt the damned thing for the umpteenth time only 2 weeks ago and I absolutely don't want to go through that pain again.
The frustrating thing is that for the first time since I owned the Tytn (6 months) all the problems I did not know about before I bought it had finally been resolved (excepting the freezing of TomTom, which still remains outstanding).
So just when I thought I could finally start to rely on the Tytn as a fully functioning relible working tool we get this.
I owned a Sony P900 for over 3 and a half years as a business tool (grant you the PDA functionality was a tad restricted compared to the Tytn) and it never failed me once! If it wasn't for a problem with the touch screen and me thinking it was time for a change I would still be using it today.
Anyone else any other suggestions on this problem please? Wiggling the charging cable in the mini-usb port makes no difference. Only a reboot does at this time.
So damned frustrating!

hungry TyTN
Hi,
I have a similar problem. I had a go for the WM6 from LVSW (2007-05-19) and the latest Radio (1.41.00.10) and a brand new out of the box TyTN.. First thing I noticed was that the unit discharges itself very quickly. I've tried various radios without any good luck too. I think it killed my battery, at least it went so low that I could'nt recharge it normally. I had the RED LED blinking fast, constant RED and sometimes AMBER. My tip is to never let the battery fully discharge here.. I had to kickstart it with 3 AA-batteries in serial, and hooked up + and - wires to the TyTNs battery so it could have a little power, or else the TyTN would not charge it anymore. I assumed it could be my old SIM and/or the battery, so I went to th store and got a new battery as replacement for testing this. I am now able to charge, but I the power consumption is far beyond what I expect, it is like 341 ma read with ABC Power Meter....! Even with radio off, wifi off, receive incoming beams off, BT off, screen to minimum brightness, nada... I was expecting a lot less... This hungry device will not last many hours, and the battery does even produce much heat during standby operation, which is not good besides from a hand-warmer in the pocket during winter time maybe... I have also tried using Bandswitch to disable UMTS as maybe the UMTS reception here is not super good, but still working... Even talking on the phone while charging it drains the battery heavily.... to empty...
Besides from all this the WM6 from LVSW seems to be super quick and stable, maybe the very best one to pick for a HERMES.
I am desperate to find a conclusion here...
heeelp..
Update:
I happened to purchase a faulty device!!! There was indeed a HW error on my brand new device so I got it swapped with another one that works. Not all problems are SW-bugs..
Thought I would come back on this thread.
In the end I had to do a hard reset and rebuild as other problems started to manifest themselves and rebuilding became the easiest option.
Rebuilding has solved the problem; however it might interest you to note that this time I rebuilt the Tytn just like I would build a PC. The OS built itself first, with its associated apps, then I added any other additional OS tools, eg SPB Mobile Shell. I then grouped my apps into a logical order and installed them one by one.
After each install I rebooted the PPC, checked that the last app installed ran ok, then tested every other app to see if they ran as well BEFORE installing the next app. This process was a little tedious but it seems to have paid off.
I have to say though that having rebuilt this piece of kit from scratch at least 20 times in the last 6 months, I just cannot count on it as a reliable business tool in the same way as I did with my previous Symbian device. Shame given how much I spent on it.
When my next upgrade is due a Windows mobile device WON'T be on my list!
WB
Wacky - Get a full back-up tool like SPB backup and you can avoid all that pain. Hard Reset to Restoring a full backup - 10 minutes maybe. Much better than re-installing all those apps everytime you hard reset. And you can create a backup before and after each installation if you wish.
Mike
Mike,
Thanks for the tip. Must admit I had not thought of using SPB backup in the way that you suggest (can't see the wood for the trees sometimes).
Now that I think I have a stable system I will back it up using this tool and create a "line in the sand", in terms of a good system backup.
I still remain to be convinced on the stability/suitability for sustained business use though.
Appreciate your input.

Similar (Battery Meter) Problem
This week, my phone reset for some reason and came up with the screen which shows the current IPL and SPL. The phone still has all the apps and data I installed, so it was not a hard reset. This happened with a 1/2 charge on the battery.
Since that happend a full charge now shows as a 1/2 charge only on the meter and this is as high as the meter will show. The phone still lasts just as long, so there is no physical battery problem.
Anyone know how to fix this without a true hard reset.
Thanks
Mardig,
The only suggestion I have is to hard reset the unit and then rebuild it from scratch. Worked for me.
In any case it may be advisable to do this as it sounds like you have other problems.
Once rebuilt I suggest you take up Mike Channon's suggestion to get a tool and backup the device. That way if you have further problems you at least have a line in the sand to refer back to.
By the way, I am not ruling out a hardware problem in your case. However my starting point would be my suggestions above.
Good luck

Strange TyTN behavior when charging
I bought a car charger for my TyTN and used it for ~4-5 months without a problem. One day a fuse went off and after replacing it with a new one and connecting to TyTN, a TyTN stopped charging completely. I checked at home with an original wall charger - nothing. I was stupid enough to try the same car charger with my second TyTN - not surprisingly it burned the other one too :-(
I got them both fixed, a car charger replaced with a new one, so everything should have been working fine. The following happened:
1. First time a car charger is connected, it works fine and the TyTN is charging.
2. Disconnecting a charger and reconnecting it back after couple of seconds restart charging, however this stops after 1 sec and the screen shows as it is not connected.
3. Repeating step 2 does nothing - no charging starts at all.
4. Soft reset - go back to step 1.
5. When TyTN off and car charger connected - charging is working - amber light is on.
6. Wall charger (original), TyTN on or off - charging is working - amber light is on.
I did hard reset as well thinking it might be a broken driver problem, but it didn't help. Tomorrow will try to reload ROM.
Any ideas?
Help will be appreciated (before I take it back to lab and spend another $40 for repair)
Cheers

This is a known issue. It also appears you've realised the soft reset workaround:
In Car charging
(May be relevant to USB/Mains charging also)
Hermes only charges when switched off
Pulling out charger lead (or interrupting power supply) while charging in car (with device on or off ) may result in Hermes only charging while turned off
Possible Solution:
a.) Connect charger with power on
b.) Switch on Hermes
c.) Soft reset whilst connected
Hermes should now charge whilst on or off.
I charge mine in the car but I do not use a car charger but a 12 volt to 240 volt inverter - so I can plug in a mains charger. Never have problems with this and I can also use it to power my laptop.
Examples here of cheap and expensive ones - small ones and large ones:

Hi Mike.
Thanks for your prompt response.
I did read that thread, however it seems that it doesn't explain point 2 in my explanation, does it?
Update: tried the method explained, however the situation is still the same - both points 2 and 5.
Regarding the DC-AC inverter - do you use a wall charger or USB output (if there is one, I found one that has both main and USB).

Unless I misunderstand something - one of the primary causes of the problem is the disconnection whilst charging leading to a refusal to charge when re-connected. To quote my post:
"Pulling out charger lead (or interrupting power supply) while charging in car (with device on or off ) may result in Hermes only charging while turned off "
I realise of course this does not explain things and is just a statement about what happens.

THe funny thing is that the other TyTN I have doesn't suffer the same behavior and charges fine, even though I disconnected and connected many times while charging.
Yeap, it's strange, unexplainable and most of all extremely annoying.
Thansk a lot for your help.
Solved!!!
Hi.
I am happy to tell that I managed to figure out how to overcome that problem. I hope it will work for all users - I tried it with 2 different TyTNs and it was OK.
The solution is to plug/unplug the USB charger only when the device is off - not a complete shutdown by long press on Power button, but a short one.
If it's OK, when plugging the lead the power button lights up in <1 sec. If not, it takes ~5 sec to go on.
Best regards,
i discovered today....when i plugged my hermes into the car charger, that it wasnt charging.
after a soft reset it charged. an then.....no problems untill about 22:00 pm. i plugged it again and...same thing, it needed a reset to charge.
what could cause this? igo may way and bluetooth gps. coz i think this is the reason.

seemingly dead Hermes.. help :(

Hey all, I've searched the forum and not found much at all..
I have no idea why this happened but my Hermes won't turn on at all, power button has no effect whatsoever and when I try to charge it I get the red light of death..
I put it down on my desk with ~80% battery last night and when I went to check for messages (by watching the service LED for a few seconds) in the morning the LED wasn't flashing so I tried waking it up and it was dead.
Plugged it into the charger, RLoD.. what the ****?
Anyone have any idea what could have gone wrong?
Usually caused by something that causes the battery to drain below 10%. Then you can get the RLOD. The charging circuit gets locked up and won't allow the device to charge. A pesky problem, but at least you have the RLOD, if you didn't then it could be the motherboard fuse.
So some things to try, non of them guaranteed and sometimes it works after trying these things several times over:

I have put my battery in my friend's Hermes and it says its 100% charged, I have put his battery in my Hermes and it still won't boot..
It's really weird.. BTW already tried your RLoD fixes, none worked.
I really hope I can fix it, I keep trying to slide open the non-existent qwerty keyboard on my Magician and it's frustrating using an OSK :S

Other than hard reset (don't think you mentioned doing that) I have only one other suggestion and that is the battery contacts. Hopefully not fractured between the pins and motherboard, but worth a try at cleaning the contacts and pushing the battery against the contacts.
If that doesn't work then I fear a motherboard fault.
Mike
Ok well for some reason my Hermes decided to boot up this morning after sitting on my desk for a night..
Weird stuff..

It is strange. Sometimes charges can build up within capacitors in a circuit and the "logic" can be disrupted. This is why sometimes it's a good idea with some faults to leave the battery out for a while to clear any such charges. However in your case with all the battery swapping and so on, I am a little sceptical that this was the cause.
If it happens again, I'd certainly be looking for a fault between battery connectors and the battery or between the connectors and the motherboard.
Let's hope that's it cured however

[Q] Help with DVP - won't turn on

Hello. I created this account so I can finally ask some of my questions regarding this phone. I've had it since the January 6th shipping, and it's really been fine for the most part. I've the 8 gig version.
Anyway - within the last few weeks my phone has been refusing to charge on random occasions (it's really very random as to when it will charge and when it won't) - both plugged into the wall outlet via the USB power converter that came with my phone and plugged into my computer.
It's been pretty annoying, but nothing I couldn't work around. It would charge eventually.
However, last night I plugged it in to the outlet and it made the noise confirming it was plugged and started charging. This morning, I unplug it and it's non-responsive. It doesn't respond to anything. I have tried:
-turning it on with the power button; holding it down for an extended period and releasing
-taking out the battery
-plugging it in to my computer (which didn't recognize anything being plugged in)
-plugging it in to a different outlet with a different cable (phone came with two)
I've let it sit plugged in for three hours now and retried all of these things and still nothing... it's dead!
I'm not sure where to go from here? I guess I should have my husband call Dell.
Has anyone had any trouble with the sporadic charging?
Are there any solutions I've missed to get my phone to turn on?
You say you've let it sit for a while, was that plugged into a power source? Try that, it sounds like your battery has gone completely flat and probably needs to sit on a power source. Failing that definitely call Dell and get a replacement battery and charger and see if that fixes it, sounds like one of those items is your problem.

Yes, it has been (and still is) plugged in that whole time. I edited my post
Yeah, something is wonky, I just cannot pinpoint it. My husband's will sometimes not charge, too. But, much less often than mine does.
charging issues
In the last 2 days my VP freezes while charging overnight. Restarts when I take out and replace battery. It will also freeze when I try to use any app while charging. I tried to use Dell chat to resolve issue but got bounced around. I even had an agent tell me my service tag wasnt valid. I'll try to call 800# when I have a free hour or so (I'm sure the call will take that long). The first two levels of support at Dell seem to have no clue regarding the VP it's very frustrating. P.S. what happens with all the apps I've purchased if they need to replace my phone?

Have you swapped batteries with your other DVP? Maybe replacement is the only option, hit up @dellcares on twitter, they have helped me in the past and bypass the whole waiting on hold nonsense with dell mobility.
@tbvnz: all your purchased appls will be reinstalled automatically if you installed them via the Zune software on your pc. The ones installed via the phone can be reinstalled from the MP on the phone, just hit the Buy button again and it will tell you its already been purchased and allow you to download it again.
Update:
I snagged my husband's battery and put it in my phone. My phone immediately came on and is now functioning. My computer recognizes it as being plugged in and it's charging.
And, my battery in my husband's phone works fine. It is fully charged and his phone is having no issues.
Certainly this is annoying (and did in fact happen to my husband a few weeks ago where his phone wouldn't respond until MY battery was put in his phone, but we chocked that up to the battery being dead {which it was}.) but at least my husband and I both have DVPs and can interchange batteries... I wonder what someone who didn't have that option would do.
Certainly confusing that removing and replacing my existing battery wouldn't turn the phone on, but my husband's would - even though both batteries are at full charge.
Thanks for the help! I'm not sure if I should contact Dell about it or not. Clearly it's subpar performance, but I've not been completely impressed by this phone in the nearly two months that we've had them, anyway.
Good to hear you are up and running. You could keep an eye on the situation and contact Dell for a replacement battery if it occurs again.
Thanks. Yep, I'll contact them the next time it happens. Anyone else had this problem??

My brother and I have experienced the same behavior on both of our phones. Most recent was his this past week, exactly as you described. It would not turn on via the power button, so I swapped his battery with mine and his booted right up. When I tried his battery in my phone it showed a full charge. That has happened to me one or two times, randomly.

I've seen that behavior in my DVP (picked it up two weekends ago) and I can tell you how to work around it.
What seems to be happening is some kind of bug when you have it connected and charging and try to turn on/off the phone. If you notice, when it seems unresponsive, the hardware keyboard will probably still light up. This is because it's actually on but the screen just doesn't get any output/input.
What I did was this:
1. Disconnect your phone from the charger.
2. Slide the hardware keyboard down so you can see whether it is lit up (on) or not.
3. Hold down the power button until the exact moment you see the keyboard go dark (off). You have to be quick because it will try to turn right back on a few milliseconds later if you still have the power button depressed, leaving it still non-responsive.
4. Wait a few seconds, and press the power button as normal to turn it on. This time you should see the Dell logo, etc. and everything will be fine.
I've gotten into the habit of either leaving it on or turning it off before I connect it to my charger (it's my alarm clock so it's on almost all the time).
Hope that helps.
my DVP won't turn on either...
Hi - i'm glad i found this post because i've had my DVP for 3 days now and its frozen about 5 times and this morning wouldn't turn on or seem to take a charge. it was fully charged when i put it down last night and this morning there was nothing.
i've stuck it into a wall outlet for now and i guess i'll just wait for it. don't know what else to do. don't know anyone else around with the same phone, so that battery swap isn't an option. pretty funny that you realized to do that and that it worked.
anyway, i feel better now that i've complained about it. thanks.
Did you try pulling the battery and then booting it up? If that doesn't work, after a pull just leave the battery in the phone and let it charge. After 20 minutes you should see it power on.
So it's continued to happen with my phone whenever I have it plugged in to the wall with the brick that came with the phone. Annoying! Basically I cannot have it plugged in next to my bed; it can only charge on my computer. So much for using it as an alarm!
I will try the power down and reboot with the keyboard out. I know what you speak of with the flashing keyboard. I hadn't tried to see if mine is flashing while the phone is 'dead'.

[Q] Help, Blank Screen, Backlight on, no picture

Pretty self explanatory. It was dead for a couple of days, I put it on the charger for almost the whole day, now I get no picture, but the backlight is on when I hold the power down a minute. I bought it at walmart, doubt I have the receipt, and didn't get any extended warranty. Is there a way to fix this issue?
I've got the same issue. I was playing Tupsu, when suddenly my n7 rebooted and there was no picture, just semi-strong backlight. When the tablet died, the battery was about 45-50% and I was charging it through notebook's usb port (original n7 cable). I tried to turn it off, but pressing and holding the power button only made it reboot once again (i assume it was rebooting, since the backlight was turning off and on in a second). I've tried it many times, with tablet plugged into wall/usb charger, and even with the power+volume up/down combination, it would still behave the same way. However sometimes after rebooting there was not only backlight, but also thin, mostly white, horizontal lines, appearing in random places of the screen (appearing and disappearing after like 50-100 ms). It would stop only after a reboot, and happened every 5-10 reboots.
I've decided to let the battery die to see if it changes something, and as you may guess - it didn't. It died estimately after 2 or 3 hours. Now it's all the same, except for when I plug it to the charger, there's only a very low backlight (still no picture) and it's blinking... It also makes this continuous "electricity-related" (sorry, I don't know what's the word to call it ) sound. After I press the power on, or let it charge for 1-2 minutes it boots up, and there's just a semi-strong backlight, like earlier.
It's a refurbished 8gb n7, which I got 5 days ago from the polish Asus online store. Oh, and the speakers weren't 100% fine, if it changes something. They were fine at first, but after i plugged headphones in and out, they were making cracking sounds when the volume was over 50% or something like that. Is there any hope I can fix it myself?
edit: the android ver. is 4.2.2, not rooted
the device is getting warm on the left side when being charged, or just turned on...
Have you tried pulling the battery for a couple of minutes?

Nope, i don't want to mess with the hardware since i've bought it only few days ago... I'm afraid it may leave some traces of being opened, i'm not willing to take the risk.
You won't leave a trace pulling the battery. Just use a guitar pick or credit card and run it round, the back comes off very easily.

Yeah that is definitely worth a shot. Just pull the battery.
Ok, I did it.
Didn't change a thing >:[
btw. I didn't actually pulled off the battery, i've just disconnected it - it doesn't make a difference, does it? and another thing - the backlight was turning on immediately after connecting the battery... with these randomly popping horizontal lines.
I've got this too!

I've got this too! Pulling the battery does nothing. Last time it just fixed itself, now nothing.
Worried I'll have to take mine back.
How did that 'fixing itself' happened to you if i may ask? And how long did it last?
Your tablet has gone into sleep mode to protect the battery from further damage due to its low level of charge. What you're seeing is by design, as complete discharge of a lithium based battery is bad for it. You should never, ever, let it sit dead for a couple days. If you do discharge it to the point of shutdown again, immediately put some sort of charge on it, as waiting to long will cause the battery's protection circuit to fail completely. Best practice is to not let your device go to the point of shutdown, but rather to plug it in when not in use. Your battery will have a longer lifespan.
Plug your N7 into the charger and immediately press power and volume down to get into the bootloader. Once there, use the volume key to scroll to Power Off Device and then press the power button. After it powers off, unplug it and then plug it back in. It should then charge normally.
You seem not to have read my posts at all. When it happened, the battery was about 45-50% and it was plugged into the laptop's usb port. It suddenly rebooted and there was no more picture, just the backlight - and it lasted for like 2-3 hours (maybe even longer)! Can a completely discharged battery power the backlight for this long? After it turned off at last, i put it on charge and i've tried the power+volume method and it didn't do anything (btw. i already wrote about it)... then i let it charge for like 5-6 hours and it didn't change anything except for the fact, that the battery was evidently charged, because the backlight again lasted for few hours.

Actually, I was addressing the OP without realizing that this was a zombie thread.
To answer your question though... yes, when in sleep mode the battery can still turn on the backlight and keep it powered for some time due to the low power requirement of a black screen. Many users that have found themselves in sleep mode actually have their tablets enter into a prolonged cycle of bootloops. From the sounds of it, your device seems to have, for reasons unknown, put itself to sleep.
Anyway, I digress... I know you've stated you've tried various combinations of the power and volume keys. Have you attempted holding all three buttons for approximately 30-40 seconds while the tablet is plugged in? If it that will force it into the bootloader, you can follow the steps that I posted to get it up and running again. If not, then it seems your best available option is to seek an RMA from ASUS. Given your speaker issue, I'd send it back regardless- you shouldn't be expected to deal with battery and speaker issues after only five days.

Yep. Many times. And even longer than a minute.
Anyway, I'm going to contact their crappy support. Thanks everyone for trying to help.

Note 3 not turning on. Sudden death? Hardware problem?

Let me start from the begining.
So the other day I plugged my phone into USB in order to charge it (I had to keep it close to me hence why I didn't plug it into the wall charger). The phone was charging, showing up as a media device on the lappy, etc. I was doing stuff on the computer then I heard it vibrate so I went to see what it was. The blue notification light was on (facebook notification most likely) and when I pressed the Menu button the screen didn't come on. I also tried the Power button but same thing. So I decided to restart the phone. Since then, it hasn't turned back on.
I tested the battery in another device and it's working perfectly fine. Neither recovery nor download mode work. I tried to do some of the tests people recommended for sudden death, like plugging it into usb and leaving it for a while, trying to kick start it (putting battery in while holding the recovery buttons) - you name it, i've done it. I even went to the lengths of taking off the back cover to see if theres any crap that got in there, maybe a loose connector, anything burnt - nothing. Unfortunately, I don't have a multimeter to see if there is a charge running through the board. Looks like sudden death to me, the only thing is - I rooted the phone on the 1st day I got it and I don't live in the country where I bought the phone so sending it over for warranty repairs would be a pain in the ass. What can I do? I would greatly appreciate your help, if you manage to help me fix my baby, I will ENSURE to send you a donation for a nice, big, cold beer (or maybe a few).
Looking forward to any answers! I really need my phone, I use it for work.
It seems like a hardware issue... you need to take it to a local store to scan it's hardware.... maybe something gone wrong while charging which made something be destroyed inside it..... hope its not the motherboard.....
it happens sometimes, when charging current fluctuate, it destroys the charging circuit and in result it damage the whole current circuit, local repair shop can solve the issue.
