TF not waking up. Sleep of Death?

Hi for some reason I cant get my TF to turn on! It was working fine all day. I left work and placed the TF in sleep mode (hitting the button) When I got home about 15 mins later, I hit the power button and nothing. I read about the Sleep of Death but this is the first time Ive had this. I try holding onto the power button for 10 seconds and then releasing it and then held it for another few seconds and nothing. I even try holding the power button for one mins and then releasing it and hitting it again and nothing. I had bout 35% battery life before heading home.
I plug it into my notebook and i get the prompt the auto play message on windows 7. double click on the TF TF101 icon and I cant see any folders. On the asus sync program it tells me no device is found. While its plugged into the notebook I held onto the power button and I get that sound coming from windows (usb sound) then I get a sound coming out of my TF and the auto play message pop up. I cant even get it to go into recovery mode (vol down + power) I am on 3.1 leaked and no root. Any other suggestion before I call Asus. Thanks

Try charging it for a few hours, the battery might've drained due to some apps keeping wifi on for the whole time (using WakeLock)

Thanks. Doing it right now. Its weird when I have it plug into my notebook. While holding the power button it will disconnect from my notebook (no longer visible in my computer) then pressing the power button again its pop up with the auto play message and i get a sound from the speakers of the TF...one of those default sound on the TF. (new email alert sound) but the screen is still black. I also trying hooking it up to my TV to see if I could get a picture and no...
OKAY got a picture now with the hdmi input but no picture on the TF. I have the pattern lock screen. do i disable it? I am able tole move around but trying to find out how to disable the pattern lock screen.

yea maybe you just drained it too much. i bet a long chargewill remedy this

I am at 50% and still no picture on the tf. Now when I try to enter my pattern for the lock screen its turning red not green like before....wtf reboot and still cant get in.

Just to share, a similar but less drastic thing happened when i got mine.
Tried it at the shop for about 5 minutes just to check everything worked fine. Packed it back into the box and took it home. About half a day later, at night when i officially unboxed it,it refused to turn on. no sound, no lights, nada. when i turned it off at the store, it still showed about 50+% battery remaining.
Same thing if i attached it to the dock.
So i left it stuck into the dock (just so i can confirm that it's charging) and left it to charge for about 15mins (while worrying that i might have a DOA TF).
The light was a steady amber from the get go, meaning >95% charge.
Anyway, left it to charge for about 15-20 minutes while trying every combination i could think of, short, 10 seconds, 1 min, more than 1 mins..
Long story short, after a while, it booted up with a 10second press of the power button.... left it to charge overnight (>8 hrs first charge) and it's been fine since.
Good luck with yours.

Okay reboot again. and its not take my pattern for the lock screen. touch the first circle and its red. and it tells me to try again...wtf....normally its turn green on the circle (the first one) now its red.

Looks like my screen is dead....smh.. I am able to see the lock screen via hdmi but its not taking my lock pattern. Every circle I hit turns red (error I guess) I dont know what else to do. I try doing a factory reset (volume down and power button at the same time) but I cant get a display on my tv when i am trying to access his mode. I called Asus and got a RMA... Just wondering do i need to send in the wall charger and usb cable too? Before sending it in does anyone know what else I could do??? Thanks

Nexus 4 wont turn on

Hey everyone, Im having a problem thats making me worry. I was using my phone today and for some reason the phone wont turn on after I turned it off. I havent dropped the phone at all and it hasnt been abused in any way. The last thing I was doing before I turned it off was trying to send feedback for the Yahoo Mail app because it wouldnt sync automatically, but even that was unsuccessful because it wouldnt send. So I thought I should just reboot it but afterwards its not turning on at all.
I tried holding the power button for at least 20 seconds and still nothing is happening, and I tried plugging in the power cord to see if that would help but it hasnt. Has anyone gone through a similar issue? Please Help
Thanks.

Leave it plugged in for fifteen minutes without touching it.

Try holding volume up + power to see if you can get into recovery then reboot from there.
Also, give some more details about your setup...
Rooted/Stock/What Rom/Kernel?

Yea I left it alone for a bit and then I held the power button while holding down both volume rockers and somehow it turned on. I dont know why this happened but I'm just glad it turned back on, it gave me a good scare though. I just hope it doesnt happen again

Mine is completely stock, I havent done anything with it yet

And may I ask what was your battery percentage level like after the short charge? Maybe the phone drained it all just being turned off... There were some cases of this here...

i wanted to add that i had a similar problem with my phone not turning back on. However, I managed to fix what was wrong by just plugging in the usb cable. I know you've tried it, but just in case someone else stumbles upon this thread (like me!) and has a problem turning on their nexus, I wanted to share my experience.
I haven't done anything to my phone other than add my old apps to my Nexus since I received it 1.5 weeks ago. It's stock. I've never dropped it or gotten water on it or anything. I charged it overnight last night and stuck it in my purse on the way to work. I think I briefly saw a working screen after I unplugged it this morning. However, the first time I tried to access my phone today was after I got to work. It wouldn't turn on, though that pinkish light at the bottom was still blinking. I tried calling it and the Nexus wouldn't ring even though the call went through a few rings and then onto voicemail. I tried holding down the power button for a while and also holding the power button with the volume keys to see if that would work, and it did not. Finally I borrowed a usb cable to plug it in, hoping the jolt of power would wake it up. That worked. It gave me the charging symbol for a little bit and then gave me the startup/loading screen with the glowing x made of arrows. I checked my battery and it was at full charge. Well, it was at 85%, which is odd since I plugged it in for about 9 hours last night to charge and there has only been 3 hours of non-use since I unplugged it. Also, if it was really turned off during those 3 hours it shouldn't have ate up any battery. Anyway, I just wanted to throw in my 2 cents in case anyone else has this problem. My brother, who gave me the Nexus, told me that he only has 2 weeks to return it if there's something wrong with it or I don't like it. Needless to say this gave me a scare, since the 2 weeks is almost up.

Yes this happened to me the other night. I was making a phone call and accidentally hit the power button. I then tried to turn the screen back on in order to hang up the phone and it would work. I tried holding the button for 15 seconds, tried pressing the volume up/down keys, and still nothing. I then put it back in my pocket for a minute or so and tried again. When I did that the screen came back on and the call was still active. Very strange, and I hope it doesnt happen again....

Same thing is happening to me right now.
Running stock. Not rooted. Phone charge was around 70% and I was on twitter and the app force closed. So I decided to restart my phone then went to turn it back on and it wont respond. Tried holding down the power button for 20 sec. Volume up and power, volume down and all 3 at the same time. Still nothing. Leaving it on the charger for awhile and the screen is blank no battery logo or anything.
Not quite sure what to do now?

That's scary

I try hold Power + Volum Down - or Volum + but get same result.
I plug in Adater and wait for it. I will check it 2 hour later.
My Nexus 4 use Stock Rom, Rooted. and this first i get this problem. Please advise me on this case. Thank
:laugh:

I'm having similar problems. Lots of random rebooting and refusals to turn back on sometimes, even though the LED at the bottom is flashing so i know the phone is still powered up. Also, sometimes when i have it plugged into a computer through usb it will get extremely hot and completely shut down, not turning back on for a long time. I called the google play store and someone is going to get back to me. I love my nexus 4 so i hope i can get this fixed or a replacement.

I had this issue too a couple of times playing Pandora through my car's Bluetooth. That was when the Nexus 4 had 4.2.1. I have not had this issue with Pandora since the upgrade to 4.2.2.
However, I just now had this issue with Movie Studio app and exporting a video I edited. It turned off its screen like normal screen timeout but then would not come back on.
I had to Volume Up + Power button for a few seconds and then release to get it to reboot.

This same thing is happening to me. Haven't found a specific cause...

Just got the same issue
Today got mine not turning on.
Managed to turn it on by holding volume up and power button together for about 30 seconds while phone was on a stock charger. After that I saw blinking orange led. When I resolved buttons there was a battery pictogram. After pressing and holding power button I finally got turning on vibration and Google logo.
The only things a made after the charging were making few photos of my cat (from the lock screen) viewing them in gallery. Then I locked the screen and put the phone on a shelf. In a hour I was not able to turn it on.
My phone has stock rom and only few third party apps installed.
I got muy Nexus 4 on 21-Dec-2012. 4 days ago I flashed to Android 4.2.2 which phone dowloaded itself. After flashing phone was rebooted.
What I noticed is that it shows 70% battery. But It was fully charged few hours ago.
30% in 2 hours! In my opinion some service/app drained these 30% by using 100% of processing power that caused overheating and/or hanging.

I too have just had this problem. And I've had it previously when making calls, the screen simply won't respond at all, its quite annoying.
This morning my alarm went off and the screen wouldn't turn on, it went on for so long I almost threw the phone across the room. I eventually held the power button and volume down/up button and then the led blinked orange a few times and the phone reset, now it seems fine.
Its a very annoying problem, and could be very serious depending on what you are doing, might have to phone the play store and tell them.

This has happened to me twice now. First time was a month ago and the second time was this morning. Phone was at 100% just woke up checked my messages turned off phone 10 min later it will not turn on. Un plugged cord re plugged cord nothing finally pressed up/down vol and power for about a minute (long minute) and the phone rebooted. YIKES!
Every thing seems normal now but I hate that scare and the fact that it has happened to me twice. Full Stock, not rooted.

Happened second time.
I was able to turn it on again by following the same steps. But this time I got some strange issue: after resolving vol+ and power buttons I saw battery pictogram with some frame with a blue background; when phone finally booted up this frame and blue background were visible through the my desktop background an screen itself was much lighter with pure colors. Only after about 5 soft resets screen seems to became nice again. Each reboot caused blue frame to become less visible. I'm confused and worried.
Also during all these reboots this frame with blue background was visible even in behind "Google" and "X" logos during booting up.
Another strange thing is that on screenshots I made this frame is not visible.

That would have to do with LCD or software..
As the battery & Google are just pictures that change. If you understand what in saying lol ?

Stupid stupid mistake!

I think I have fried my Nexus 7.... didn't even think about what I did how stupid am I....
I decided to wire up a Hella connector to a USB cable the idea being to plug it into my phone for charging on the road... I then had a not so smart idea to use my OTG cable to connect the USB A connector to my Nexus 7 to see if it worked...
Nexus 7 booted past the bootloader and then nothing.... I realised then how stupid I had just been...and still nothing...
Presumably I've run a shed load of power down one of the data line..... what a fool.....
ARGH!!!!!!! anything I can possibly do to salvage it.... please!! :crying::crying::crying:

you could try something ASUS support told me, press all buttons (volume + & -, power) for 30 seconds, and if it won't boot after that, you should get a RMA

Going the RMA route would be costly. If it is dead, he'd be better off just bring a new N7.

Thanks for the suggestion but no it hasn't worked...
I've had the N7 plugged into the charger for the last 30 minutes or so and when I went back to it the screen backlight was on slightly (you can see if you look at the screen from the side)... but the whole unit was really really hot... I've obviously disconnected it but now can't get the thing to turn off, if I hold down the power button the screen flicks off but then back on.

I would think that "broken display” units on eBay/CL probably have working mobos and batteries, as the owners are trying to dump them because of the broken screen. But, buying used is a crap shoot.
Nice that Google is selling N7s at cost (or even a loss) - but it does mean that any oem component replacements will be a significant fraction of the original price.

I was reading in Play Books when my N7 shut down due to low battery. I plugged it in and it wouldn't charge or boot and I noticed a faint light bleed and faint dots streaming from right to left on the display. I tried things like holding the power button for 30 seconds to reset, holding vol down and power to try to get to recovery, but it wouldn't take. Finally, with it plugged in, I held down the power button for just about 10 seconds and backlight and dots stopped. A few seconds later without pressing anything, it booted up. It would start to charge, but if the screen timed out, I was back to the earlier state and it wouldn't come on. So I got it started again and immediately went to developer options and checked Stay Awake while plugged in. Eventually the charge built up and I'm back to normal, at least my N7 is normal. I only mention this because the OP talked about the faint backlight and it may be worth trying.

A standard hella charger outputs 5V at 2A which is the same as your N7 original wall charger.
I doubt your problem came from the charger, it might be softbrick at an unfortunately moment.
I came across a similar problem when i was editing a custom kernel.
If you tried every method to shut down the device and failed do the following:
1. Open the case (it's quite easy to open with a plastic card)
http://www.ifixit.com/Guide/Installing+Nexus+7+Battery/9895/1
2. Unplug the battery and hold the power button 30 seconds (with the battery detached)
3. Let it soak for 10 minutes
4. Reconnect the battery and close the lid.
5. Put your nexus 7 in the wall charger, and you should see the battery bar on the screen.
After that, let it charge a few minutes and boot the device.

Did you take the phone in for service? What did they do to fix it, if they fixed it... I have a dead phone and need some answers if they are out there. I'm looking through every post that has anything to do with this subject and coming up blank - just like my phone's screen!
Part of my issue is that I had a shut down from out of nowhere on NYE. I was able to bring it back up with the power, volume up, and Bixby combo the next day. Foolishly I assumed it was a fluke and went right back to using my phone just as I had before. I saw an article about disabling the Bixby button, which seemed to be the thing to do... When the phone shut down the next day again, I couldn't bring it back because I no longer have a Bixby button for the combo. It's been down since Jan. 2, and I'm at my wit's end. Can you please update your phone status? I'd appreciate it if you can!

Lol disabling the bixby button in software does not mean you can't trigger download mode. That level of software has no idea what packages you disabled ?

Did you have Substratum themes applied before updating?

Happened with me last night, bunch of updates and then black. I was gonna send to warranty, then someone told me Power + Bixby + Vl down and it worked. How can I find out what did it

When I called Samsung, they were clueless how to get it started again as we walked through all the button combinations they had. It was fully charged when it stopped working, both times. The second time it took me a few days of trying on my own, calling, Samsung and then going into their repair store.
They took it back to work on it after I explained what was going on. He tried several things and came out and told me it may need a replacement but wanted to try one more thing. Hours later, he came back and said he hooked it up to a charger and it had been dead. Once it started charging, it showed the green battery, lightning bolt and blinking circle. It still didn't start normally, but the three button combo worked at around 20%. I'm not sure if he tried before that, but it came back on.
I've discovered that my handset is extremely sensitive to cold temperatures and shuts down. I'm in the Midwest and have been working outside in a tent like structure. I listen to music, books, or podcasts while I'm working. Many times, I will put my phone on a shelf while charging but still listening. The phone shuts off and first I have to wait for it to warm up, then it has to drain the fully charged battery, and then I start charging it again. After the first time on my own, I did the button combo right after it started taking a charge and it worked.
I'm not sure if a replacement phone is the way to go, because if this is common on the S8, I might end up with another dud that would just frustrate me more. I like the phone, but this quirk is annoying.

Last night my phone was charging and accessible fine. This morning I have a green light at the top showing I assume that it's charged but the screen is totaly black. nothing I do brings up any screen. I tried all the button combos I tried plugging it in to the charger and nothing shows any kind of reaction. I tried plugging it into my computer and the computer said it was setting up device QUSB_BULK. Then said it was set up but even after it supposedly complete I could not find the device. What the hell?

S8 Black Screen
Is the green light staying on? This happened to me on one of the many shut down times I experienced. I think I narrowed it down to my phone not liking cold temperatures, but I don't know if that is your phone's issue. It hasn't happened since last winter, so I haven't needed to do any of this for quite some time, but I'm trying to remember all of the steps I took.
I'm gonna suggest getting the battery drained back down to zero. In order to drain the battery when it's black screened, I kept trying all the button combos repeatedly for, it seems like, maybe three or more days... I couldn't tell if it was dead on several of the occasions, but when I had an indication light, it went off after days of doing any and all button combos, just to drain what battery I could.
Once you do that, while keeping it out of any extreme temps, (if there have been any) then plug in the adapter that came with it, using a good quality USB-C cord and charge it again and see if the charging screen comes up. (The Fast Adapter Charger that connects with USB 3.o is the best to use. Samsung wanted me to use the original cord, but I have no idea where that is! I just used a good quality cord.)
If that doesn't do the trick, then it's not the same issue I had, and I wish you luck on finding out and getting it fixed! Don't forget to update the site for others to find out if your tricks work... (You can still try this, but it may be just to rule it out as a possibility.) Try draining it more than you first did, and then plug it in again to see if it takes a change.
If it is taking a charge again after draining and plugging in your power cord, wait until you get back up to at least 20% and then try the three button start (Bixby / Power / Volume Up at the same time) and make sure you hold them for up to 30 seconds or until it kicks on. One time, I think I held it for almost a full minute. But it did take the change, restarted on the three button combo restart, and didn't have any new issues from its down time.
If this works for you, come back and tell us! If not, come back and report what you try and what the results are.
I really hope that helps! Good luck!

Sounds like a system problem, you can try to use the button to force a reboot, if there is no response, you can try to reinstall the system, if this still can not be solved, then you may need to replace the new screen, you can go to Witrigs to see Note 8 screen, they There is an original Note 8 Super AMoled screen for sale. The price is also relatively low.

Poco m3 turned off during an update

I am sorry if this is a dumb thread I am just worried. I was watching my Poco M3 update up to 60%(my battery was on 68% before starting the update) then I started to watch TV and didn't pay much attention to the phone. When I looked at it it was off and i thought that maybe it is just in the process of rebooting or its already on the lock screen .Because I thought it may still be rebooting I just placed my finger on the fingerprint reader because I didn't want to risk turning it of by pressing the power button. My phone didn't respond at all. I haven't tried to hold the power button because I'm worried that its still in the process of updating. What should I do ?

Never mind. I had to hold the power button for 10 seconds and it turned on. I am sorry for wasting your time. I was so worried since it was a new phone and I couldn't afford a new one. I am sorry again.

This post was usefull, it happened to me too. The phone wouldn't even show an image when connected to a charger. I waited for a while, entered Fastboot succesfully and then, after the second (on the first one remained stuck on the MIUI screen) 10s power button push, it succesfully booted

It happened also to me during update to 12.0.8.0, but I used Power and Vol+ and then Reboot to System.
It was a moment of anxiety.

It happened to me to. It is a branch new phone and I got so worried that I might just have bricked it. Fk Xaomi.

just happended with me right its on MIUI Screen hope its get on
Update: Just Booted In Fastboot Its on Screen now

Same thing just happened to me too. My phone is not turning on at all. I tried holding the power button for 10 seconds as discussed here, tried fast booting, tried connecting charger and starting. Nothing is working. Going into panic mode.
**UPDATE***
After leaving the phone alone for 24 hours in which time it was completely unresponsive to anything I tried, I connected the charger and just pressed power button and it decided to just start normally. POCO needs to address this situation.
**UPDATE***
Phone is not responding again after restrating. I give up on this phone.
