[Q] What would cause the phone not to wake up?

I picked up a Captivate and used SuperRooter, got Clockwork on there, and put on some apps. What's odd is that if the phone sits for a while and I try to wake it up, the screen doesn't turn on - even after waiting like 3 minutes. Besides flashing back to stock, is there anything I can do to see what might be causing this? Would a logcat via ADB help? When I set it down and use it every few mins, it's fine. It's just doing the weird not waking up thing when it sits for a while.

I've had mine since aug. 2nd....this just started happening to mine over the past few days, where it'll shut off while sleeping. Its only done it 2 or 3 times tho. Mine isn't rooted.
Seems this is happening to a bunch of people, some have had to remove the battery to get it back on....i haven't had to do this yet. (knock on wood)

Is there a way to disable a long press of the Power button while the phone is locked? I'm wondering if that is part of the problem.

Are you using SetCPU? The ondemand CPU governor is known to cause this problem.

Setcpu was causing my vibrant to do the same thing, deleted it and everything is fine

If SetCPU is an app, i haven't installed that one....

Removed it and it is still doing it. If the phone is plugged into anything (weither stay awake is on or not) it seems fine but when it is unplugged, it shuts off every few mins. My girl has this phone for the week and I won't see her til the weekend but I was reading on Android Forums and it seems alot of people are having this issue. I will flash back to stock and see if it helps, but I have a feeling it won't help.

i think its the root i mean i it did taht after i rooted i just got my replacement seeing if itll act up if not ill keep it if it does im jumping ship to buy a international galaxy s

Does your phone smoke a lot of pot?

I'm actually wondering if it doesn't have something to do with power handling with a full battery. I had to swap mine out because any time it was charged 100%, if it slept it turned off. After a few restarts or me playing with it enough to drop it below a completely full charge it was fine. I don't know, but if this new one does it I will just return it and look for something else :_(

well ricparr and anyone else i would just return your model saying its defective and get a replacement tahts what i did

Maybe some peoples reboots are on accident

Yesterday while toggling airplane mode I got a reboot. First yet and it was on gingerbread..i just had another one while accident pressing power for too long..
the phone reboots just holding power even if the screen is off. Maybe just maybe this button is getting pressed for too long I their pockets or just pressing power to toggle airplane mode and its rebooting. Or maybe something with this function bugging out...
Anyone else notice phone reboots just holding power for too long?
Edit:Im almost positive this is what caused my reboots

My phone was on the charger last night only for me wake up and it was off. Full battery when I powered it on.
Doubt its being turned off my accident.

As I said, some people.. Maybe some is legit but others are this issue..
Or like I said, something related to that. Maybe bugging out or something.. Just seems weird that holding power causes a reboot.

A lot of my reboots were spontaneous when I wasn't even touching the phone. Also when it was charging overnight.

Dont know just a thought.but I'm positive this rebooted mine.

Definitively not by accident!! And the damn thing reboots by itself every 5mn for a few times while I was watching it doing that while plugged in, then turns off by itself in the middle oh the night, I'm getting another one, and another one until I get a working one with no light bleed. I'll receive my 3rd one in a few days.

Mine just did it again. I didn't have the problem on the stock rom, CM7, EaglesBlood or any other rom aside from the unofficial Gingerbread leak.
The rom itself it very nice considering CM7 has weird issues of its own, but resetting/locking up is a big no-no.
As I said earlier my phone was off this morning after flashing the leaked rom last night. I wiped several times this morning, flashed Eaglesblood, wiped again, and again, flashed the leaked Gingerbread, wiped and wiped again.
Set the phone up but didn't install any apps (testing). Cooked breakfast; fine, watched a TV show; fine, took a shower; fine, got dressed; fine, stepped outside for a second; locked up.
The phone was on because when I pressed the power button the touch panel lit up. The lockscreen showed for a second then went out. Then it was unresponsive. I held the power button down for a few seconds, which turned the phone off, then held it again to turn it back on.
Sucks. Must be the rom. Weird why the stock didn't do it, nor others. Others are claiming theirs are fine.
It is SO weird how these problems aren't across the board and are so random. Everything points to a kernel which wasn't included in the lacked build. Hopefully when the official one comes out, we'll get an updated kernel to go with it.

I think it's the overheating problem. My first phone was very hot and had 3 reboots in 5 days. New one I have has no reboot yet and doesn't get as hot like the other one. PCs get BSOD or freezing when overheating. G2X gets Black Screen of Death and freezing.

This could very well be. especially since a lot of people have reboots when charging and that generally makes the phones temp higher...
Luckily I'm good...

If I had the rebooting problem, I would definitely exchange my device. I haven't had any reboots or freezes though.

U could be right but my phone shuts down a few times right after charging. But then for the rest of the night it won't shut down anymore. Sometimes it shuts down in the middle of the night too, it's very randomly. How do u explain that?

Pattern to my reboots - do yours have a pattern?

So over the last few days my phone seems to have settled into some sort of weird pattern with reboots. Although there are outliers, in general it always seems to reboot between 19-24h of uptime and nearly always at like 45 or 50 mins past the hour. It's the most bizarre thing in the world and why I think there's some funky software doing it. I don't have true random reboots, but I can't figure out what it is that is doing this. Very odd.
In all cases my phone is sitting with the screen off (I've NEVER had a reboot while using the phone/screen on) but it doesn't matter what radios are on, WiFi, BT, GPS (can be off or on).
Last time I ran "CatLog" a logging app from Market and had it write to SD logs and a reboot happened but it only by default writes every 200 lines so the last line in the file was probably not the last line in the log. I'm going to try again later and set it to write every line or few lines so I can see the last entry in the log before a reboot. Might shine some light on it.
Just find it very strange since it's a very stable and capable phone for about 18hrs and then it just craps on itself. Very strange.

finally. I too just think it is some weird software or driver bug because I was running EB 1.0.4 FINE for like 3-4 days and loving it... then it started resetting almost hourly. I didn't install any other apps past my initial normal set of apps.
Even CM7, seems like it is fine for a few days, then gets crazy. As long as I put a new nightly rom on it every day, it's good.
I didn't have any issues with stock though and didn't seem to have issues with CM7 for a while until lately.
The leaked GB rom causes lockups immediately out of the gate seemed hourly.
I use CM7 as my main daily driver now but I think you are on to something. We are talking about the Screen of Death right? I don't think mine ever reboots, but gets stuck at the lockscreen where the the display comes up, swiping to unlock vibrates then the phone but doesn't change screens to desktop. The buttons and click/drag widgets work even though you are looking the lockscreen.
I've never had my phone powered off in my pocket or noticed it "rebooting". Mine just has the SoD that seems to follow your pattern idea. They may be related. Stock roms may reset once it locks up, where CM7 just keeps running in its locked state.

I have a really strong sneaking suspicion that every G2X reboots but not everyone notices. Also if you naturually turn your phone off once a day or so you won't notice it perhaps or even a few days. The phone reboots pretty fast and the only way I've been noticing (except the times I see/hear it happen) is I have an uptime widget on my homescreen so it's obvious.
Same thing happened with my Droid Incredible btw...when it first came out there were all kind of random reboot issues. After a software update I would run that phone hard for 30-45 DAYS straight without a reboot.
It's annoying but I think it's just a matter of time before the G2X is the same.

I just hope that update gets here sooner than later.

I dunno. The tmobile jingle is pretty loud and I never hear it. CM7 has a silent one so possibly there but I dunno.
I use my phone pretty often and never had the suspicious that it reboots. My phone stays very cool during my usage compared to my nexus and other phones
My uptime was 4 hours since I reset it last. I'll monitor it with results. It'll be hard not to flash but I'll keep track and see how far I can keep it online.

i have not had any reboots or waking up to a dead phone ....with the only fix is a battery pull.... ever since I started.
1) my over night charging / long term charging to 100%... only on the LG charger that it came with. Only short term...maybe. less than an hour and not to a 100% charge on a non LG charger (car charger etc...)
2) I restart my G2x every morning when I take it off the LG charger..(after I take it off..I did it once while on the charger and had an issue... (there is definitely an issue related to when it charges to/ around 100% charge)
Just my 2 cents.

Pattern to my reboots - do yours have a pattern?
Hold Power and volume up simultaneously for about 10 seconds.

I've had my phone since Friday, but the only time I had the rebooting problem was this past Saturday when it rebooted four times within 15 minutes or so. Before the rebooting began, the phone had slowed down to a crawl, so I went ahead and rebooted it. After that, I sat it down and watched it reboot a few times on its own. Luckily my iPhone 4 owning co-worker was completely unaware of this issue since we tease and bicker with each other every day over Android and iOS .

I can guarantee that mine don't reboot. I've had it up fire days, checked the up time and play with it constantly.if it rebooted in the middle of the night I would hear it or the uptime would be close to zero in the morning..
I have a way stable phone.running stock, rooted with bloat removed.. I love this damn stable phone.

Everything other than smart share, tegra zone and qik. Of course have nova and need for speed also.
Oh also have car home froze..

Maybe jumping the gun here but I tried to let mine go as long as it could without resetting it. I kept tabs on it and it was running awesome the entire time (#33 CM7).
Last time I noticed my phone on was like 17:33:xx hours. I had like 44% battery left. Next thing I know the phone is off. I tried turning it on and a battery icon flashed and turned back off.
What I am thinking is that perhaps the faulty battery driver is telling the phone that the battery is dead and preventing it from booting up. We were talking in another thread and I said something that really makes sense: If the battery driver tells the OS that there is 0% battery then it will just reboot. The battery itself may have a 50% charge left. That would explain the random reboots too (the battery driver telling the phone there is 1% left and cutting power). Maybe a hard reset semi-corrects the problem but eventually resets again due to false information.
My weirdness/powered off occurred right around 18hours. The phone could have just died too.
Almost need a Voltmeter so someone can test the battery (or however it can be tested).

Yes I know the battery driver is part of the problem as can be seen on CM7 builds but what's odd is my time varies so for a long time it would reboot every 17-20 hours, now all of a sudden it goes to 36 hours before it usually reboots. Looking at logs it doesn't appear to throw any major errors before a reboot which implies that it's a a kernel panic or low-level fault. At this point I've given up on trying to find the issue since it's been repeated over and over that T-Mo and LG are releasing an update. Might as well enjoy the phone and wait for that to come out

Amen. Just keep flashing CM nightlies and you'll never worry about it.

battery icon says charging but not plugged in

hey im running on stock and have had no problems up until a couple of days ago where the battery icon on my G2x shows that its charging but i dont have it plugged in at all. what bothers me the most is that my phone wakes up randomly as if it has been plugged to the charger. Anyone else have this issue? i havent heard of a problem like this happening to anyone else. Any ideas? oh and yes i did a complete wipe of everything but the problem is still there.

Just had this happen twice yesterday, but even worse off. The charging state toggles about every half second. When I try to turn the screen off it will pop back on and the "Charging (XX%)" will flash on and off on the lockscreen, keeping the screen on. It stopped about 30 seconds into the madness both times. I'm not too worried about it. I'll exchange the phone if it becomes an issue. Kinda curious what it is though.

I am facing exactly the same problem as quoted above. Got my G2X day before yesterday and this problem starts to happen as soon as (and every time) the battery comes down to 70%. It does not happen when the battery is full. I am on Android version 2.2.2. Haven't been able to upgrade yet. Did you guys try upgrading to gingerbread? Does that solve the problem?
I have a strong feeling that it is a software problem, not a hardware one. What do you think?

I dont have the same phones as u guys, but my problem is the same, it thinks its charging but i dont have it plugged in. I'm sure its a software issue, rebooting, removing battery, hard resets dont work. did any of u guys solve the problem, if so, any clues as to what the issue was that i can look into?

Did it get wet?? I had this problem a while back when I wiped my phone off with a damp towel. Some water had got on the connector at the bottom. I just pulled the battery and got some canned air and got it out. Haven't had that problem since

[Q] Randomly Powering itself off? Battery issue?

So I've had my 16gb Tablet for a few days. Upon first power up, I ran through all the updates, including 5.0. When all the updates were done, I did a complete reset of the system to get Lollipop nice and fresh.
I've noticed that a few days ago, I left the tablet on my nightstand at about 50%, the next afternoon it was completely dead. I didn't think much of it, thinking maybe a program went crazy and sucked it dry. It happens.
Yesterday I left it on my bed at 64%, a few hours later I went to use it and it was powered off. At least I thought it was powered off. I'm noticing this unit might have bad buttons, as they are really squishy and don't have a lot of feedback for the up volume and power. So after pressing the crap out of the power button, it seemed to power back up. It greeted me to showing about 60% battery. Ok, that was weird, but not the end of the world. I plug it in to charge to 1005%.
Last night, I unplugged it at 100% and left it on my computer desk. Just now (next morning) I went to flip open the cover and it wouldn't turn on. I try hitting power and nothing. I hold the power down for about 20 seconds and it finally powers on. It boots up to 48% battery. Now keep in mind that I didn't do anything to it last night when I unplugged it. As a matter of fact, I didn't open apps, but I made sure I swiped all open cards away so nothing was running.
Sorry for the long post, but I want all the details here.
A couple questions:
Anyone else having random sleep issues where it won't wake up? I thought a lot was resolved going to lollipop?
Anyone have issues with soft sloppy buttons with no travel or click on the side? This is my second unit and I thought the first one had better buttons..

I'm having the same issue. Once it goes to sleep, sometimes it randomly just shuts down on its own. When I leave it on overnight, it's almost guaranteed to be off in the morning. Since I've come to work today, it's already automatically shut down twice. What the heck is going on?

It was the first thing I checked, and yes, it's disabled. I did a reset of my device yesterday and I've only had one random shutdown thus far. Not ideal, but still an improvement....

You need RMA, Please read this : http://forum.xda-developers.com/showthread.php?p=56907689
Same story for me, tablet was defective, battery drain even in airplane mode with no application installed. If your tablet do this, don't lose time and change it.

I've just purchased one and it's happening exactly the same, it happens constantly, also the battery drain is considerable.
I'm in Lollipop, and I've already done a coupe of factory reset.
Does anyone know if this can be repaired somehow? Or I'll have to return it...
Thanks!

Never requested a RMA to NVIDIA, are they fast? I've bought the tablet in Amazon, I have doubts yo who should I request it.
Thanks

So you should request amazon, unless Nvidia offer you a direct replacement in their forums.

Quick question. Does everyone here experiencing shutdowns have a case with an auto wake/sleep feature?

I too have this issue. Auto off is disabled.
I tried going back to gingerbread and the power issue is non-existent. Once I do all the updates to Lollipop the issue returns. Think it's an issue with the rom, since gingerbread works flawlessly.

I have both a skin and one with auto wake and my k1 has been shutting down on its own even with just tye skin on it.
