Running stock, latest ota(not ics), with root. Once every few weeks I get a situation where I use the phone, turn off the screen and put it down. Look over a few minutes later and see screen off but realize the buttons are illuminated. If i hit the power button to turn on the screen nothing happens. If i hold the power button the phone reboots. Seems every phone I've ever owned has ended up with occassional random reboots. Just wondering if others experience this to.

When my Photon is completely off, it takes 4-5 on button presses to get it to turn on. This only started happening recently. Strangely, there's no problem in turning the screen on and off once the phone is actually on.
Anyone else have this issue? This started occurring to me within the past day.
You have to hold button down for about 5 seconds
Sent from my Photon.
I usually have to hold my power button down for about 5 seconds as well before it'll power on. Nothing odd there.
My G-Tablet was working great for the last 6 months, the day I bought it, I flashed it with Cyanogenmod 7. Last night I was listening to Pandora, while reading Manga. I set it down and went to sleep.
When I awoke the Tablet was off, still plugged into the AC adapter. And refused to boot. After trying to get into the recovery thinking somehow it bricked itself, I noticed the screen would flicker ever so dimly. So I ripped the back off and unplugged the power thinking maybe it's not really off, maybe it's locked.
Alright, so now after holding the power button down for about 30 seconds it starts booting, I see three birds, the words android, the Cyanogenmod logo and then it goes black. After about a minute of that, I assume it booted. Still starting at a completely black screen I pressed the volume button + and - and I hear the beep boop. Alright so it booted. Where is my VIDEO?
I hold down the power button for a minute, I press the volume buttons but no sound. Ok, it's off I'm guessing. Lets boot again. This time nothing, completely blank screen, until it gets to the Cyanogenmod Logo. The video comes on for about 3 seconds then off again. About 15 seconds later, it comes on and I see the android robot riding the skateboard for about 3 seconds, then black again. It again finishes booting, I play with the volume buttons and I get the beeps. But absolutely no video.
One other thing, is that while booting. It ALWAYS turns on the video for the little robot on the skateboard for 2-3 seconds.
Has anyone experienced anything like this before? I'm totally at a loss, I really hope the GPU is fine.
I miss my tablet
If it turns out to be a hardware problem you should have a year long warranty from viewsonic. Someone who has had experience with the warranty process will have to tell you whether or not they will deny your claim if it arrives with CM7 installed (I haven't dealt with them). If you are able to NV flash before sending the tablet back in you should be golden though.
Thanks for the advice Bret.
I had the tablet sitting on my desk, I booted it up, still a black screen but I could hear the volume beeps. I let it sit there for about an hour, running on battery. And wouldn't you know. The screen came on. It's been working perfectly so far, I can reboot, shutdown, let it sleep ect. Not a single problem. I would absolutely love to know if it was a software glitch, or what. Seems my GPU is fine, rocks 3d apps no problem.
But I know if I don't know what caused this, more then likely it'll happen again and I'll flip out.
Open your gTab up and reseat the cables going into the LCD panel.
You say you have been running CM7 for ~6 months? have you had to reflash you system at all in that time?
The reason I ask is that I have had issues of the system corrupting itself over time, and almost every time I had reflashed, everything seemed to go back to being fine. Who knows... maybe its time to do a backup and flush the system for good measure..
So this morning after watching several videos online last night, on my non-rooted nook, the wireless wasn't working.
When I would try and go into the B&N wireless settings screen, it would do nothing (go black) or say that wireless is stalled (do you want to wait or force close). So I forced close, hoping it would reboot automatically.
Well, I tried to turn off the device and the screen went black but the backlight stayed lit like it was supposed to be on for several minutes after I had powered down.
Eventually I got the blacklight off (it might have just gone off by itself), but now it won't turn back on.
The battery was at 30% when I tried to initially power it down.
I haven't tried the power and n button 30 second cycle, because I don't want to lose what I have on it. Any ideas of how to get it back on, without factory reset?
I can remember some other issues like this were reported. I believe one solution was to let it charge a few hours and attempt to power back up. Not sure if this will work for you, but give it a shot.
Plug in Charger (Might wake it up).
Connect USB to computer (Might wake it up).
Hold in power button 20 seconds to power off then power on.
The last option just worked for me for a black screen (Loop?) issue.
When that has happened to me (and it has), I held down the power button for about 30 seconds. Then let the unit sit for a couple minutes. Then held the power button down for about 5 seconds. Eventually, it always started back up.
30 second hold
The 30 second hold and wait worked well. Thanks.
Glad everything has worked out for ya!
I have no idea what caused this, but I can briefly explain the scenario..
After the .21 update, I found my Prime to be a little lag-gy (you know like when your desktop is on for quite a long time, you try to reboot), so I wanted to turn it off, then turn it on again. To my horror after I turned it off, I could not turn it on again. All I can is have this vibration that's supposed to occur at 3 seconds normally, at 12 seconds of holding down the power button.
After doing some research , others that have similar issues of unable to boot tried holding down the power button for 30 seconds.. 60 seconds.. and multiple times.. I've tried it, but nothing worked.
I tried the cold boot, holding VOL Down plus power button as well. No luck.
Lastly, tried the soft reset button. Tried it holding down with power button and pressing it separately. Still no luck.
I tried it with and without dock. Everything almost the same except when I
'close' the tablet with the dock.. holding the power button does not do anything, but when i 'opened' it, 3 seconds I will get the vibration, but nothing will be shown on the screen. Totally blank.
Anyone can help? I'm going to send for RMA at worse scenerio but I need help asap cause I need to use it later in the day. :/
EDIT: Oops forgot to include something else.
That was 3 days ago, I managed to get it working 2 nights ago, but after I went to sleep, and woke up. Heck, its off again. I have no idea how I got it working. All i know was, I brought it out, didn't use it, about after 8 hours I reach home, I sat on my chair thinking of sending it for repair and tried my last attempt to on it, it loaded perfectly. Then... this happened...
After I connected my tablet to the computer and try to turn it on, Windows detect APX. But the driver installation. Wonder if this information would be useful.
Again new information don't know whether this is useful or not, my volume up button was faulty about a week ago. Sometimes my volume just automatically goes up on its own, probably the button is spoilt that its permanently or most of the time held down. And after some Google-ing, volume up and power on apparently causes the tablet to go in this APX mode..
So I had my Galaxy S5 from T-Mobile for a couple of months and it has been working great, especially after the recent Marshmallow update. But as of late, my phone would crash and keep restarting until it starts up normally again. Over time, it would get progressively worse and it would take longer to boot up over the course of a couple of days, and when it does finally manage to boot up and work, pressing the power button would crash the phone and throw it back into a boot loop. I left the phone alone for a couple of days and came back to it to try to boot it up again, and it worked well! It booted up first try without any kind of restarts and the power button worked a couple of times until... it failed again when I pressed the power button and it got stuck in a boot loop again. And after a couple of minutes of being stuck in a boot loop, it would boot, but the screen was black. The LED at the top of the phone and the lights from the capacitive buttons would work and I know the phone is working it's just that the screen is not. I can manage to turn off the phone without the screen by holding the power button and guessing where the "Power Off" button is. And while the phone is in this state, when I press the power button the phone would lock like it's supposed to. I've tried taking out the battery and holding the power button for 2 minutes and letting the phone rest for another 10 minutes but it doesn't seem to really do anything. I've tried rooting it before but failed to, but I don't really think that's the problem. If you guys have any suggestions I would really appreciate it! Using my old Galaxy S3 is kinda annoying, especially since Pokemon Go doesn't support it. Thanks again!
If you guys would like a video of some sort to see what's going on exactly then I'll be glad to make one for you guys.
Did the problem start after you tried to root? What did you use to try and root your phone? What baseband are you on? Do you have stock or a custom recovery?
From past experience, symptoms indicate a stuck power buton. FWIW.
