Hello!
So around a month ago I repaired the broken screen of my P30 Lite, I tested everything and it seemed to be working fine back then.
Since then it has just been sitting in its phone box on my shelf.
Now, when I try turning it on, it wouldn't turn on.
I honestly don't know what happened to it, the battery is working just fine and I repaired the screen a month ago and, back then, the screen was working perfectly fine.

You can try to perform a hard reset also known as a power cycle to fix this freeze. This cuts the power to your phone entirely, forcing it to shut down and boot back up.
Don't own this type of phone - but that method typically does it:
Long-press the Power button and hold it down for thirty seconds or longer.

Had to get my one day old Nokia 800 replaced today.
Got everything setup last night and decided to power it off just to give it a restart. The phone would refuse to power back on. No amount of button pushing/reconnecting to the power would make it start up again. No power, nothing..dead.
I managed to get it to restart after performing the three button reset. No problem I thought maybe just a one off. Turned the phone off and put it on charge overnight and this morning the same problem returned.. Could not power on. This time the reset would not work at all, no matter how many times I tried.
Carphone warehouse swapped it over in store today for another handset. Hopefully I'll have more luck with the replacement.
Edit: already seen someone else mention a similar problem on here. Hope there's not a bigger issue.
How do you perform the three button reset? My phone randomly decided to turn off whilst I was driving and now it wont turn back on
Yes I've been in that spot as well. For five minutes the phone wouldn't respond to any power button press. Long, short, whatever. I was already starting to slide into panic mode when it suddenly came back alive on another short press.
It's not the only hardware problem I've encountered, I also have problems with touchscreen and buttons and a loose part inside the device.
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!
Hi,
I've had my Z3TC for around 5 years now and still love it but has been having a few issues recently, notably the battery life is getting worse, but it's still usable. However, yesterday, something strange happened to it. The power on/off button stopped working when I pressed it once (double press for camera still worked), so I couldn't turn it off or turn the screen off (other than my closing the case cover) and one of the volume buttons didn't work either.
Then, the battery dropped from around 40% to 0% and it shut down. I charged it overnight and this morning when I turned it on, all the buttons were working again but it was in safe mode. I tuned it off/on multiple times, restarted it, rebooted in safe mode then rebooted again hoping it would go to normal mode, but none of this work.
I've now done a full factory reset and it is still stuck in safe mode (and I've restarted it, turned on/off multiple times). Are there any suggestions for how I can get it back to normal?
Thanks,
Frank
Nearly the same thing happened to me. It happened about 3 years ago. The power button stopped working (just like you), so I chucked my Z3TC. To this day, it was - and is still one of the best - phones I ever had. I ALWAYS got asked questions about it. I own an iPhone now, but I still love the Z3TC. The camera was terrible, but everything else about the screen was solid. Just wished they updated the OS on it, but due to Google and the chip restrictions, never got far. Either way, I'll never forget this phone. Pity our time came to an end due to that power button breaking.
Also stuck
Same thing also happened to me.
I had the tablet for quite some time and the battery would start going straight to 0% from quite a high number. And also my volume down button doesn't work and I am stuck in safe mode. Rebooting, poweroff, etc doesn't make it get out of safe mode.
Hi,
Just few minutes ago my brand new phone just broke on me. I was holding it in my hand, locked screen, like minute later I tried to unlock it to no avail, screen just stayed black. There was a sound when I touched it by the fingerprint sensor, but no light up from behind the screen. I tried holding down power, then power+volume up, phone only vibrated, no reaction on the screen. I've connected it to the charger, and now it seems to be in bootloop - screen is turned off, and every few seconds phone vibrates. I've managed to somehow turn it back on once, phone booted to system, everytthing worked just fine, then I locked screen and it just stayed black, now I can't reproduce that, can't even turn it off, it's just vibrating every so often. Did it really brick in my hand? Software of Hardware? Everything worked just fine, maybe battery was draining a little bit too much for my taste, (15-20%/hour with screen on+lte/wifi) but 120Hz refresh rate+bright setting and AOD turned on 9am-9pm could do that. Do you guys have any suggestions, or I'm expecting trip to the service?
Sorry, but i cannot guess any reason. I am stumped as this bootlooping shouldn't beb happening... Very strange. May be its better to show it to service center guys.
Btw, i had tried this on my previous android phone to shut it down, like a hard shutdown. I had pressed power + volume down + volume up keys together to shut it down completely. Basically by pressing all the 3 keys. If you want to try, you can try it. I have not tried it on my GT, but had used it on Oneplue 2 and Honor View 10.
Hope your issue gets resolved asap...
Okay, I've contacted support via livechat, they told me it's definetly just software glitch, and to resolve this I have to wipe dialer cache (?) and all system settings - I did it, everything worked just fine, but today, again, same thing happened. First time phone just died in my hand, second time it was while listening to music via Pulsar, today I was just sharing wifi as a hotspot, phone randomly broke connection and would not unlock, but still I could tell it was on, because of vibrations and sounds. Not a software glitch after all? If I manage to unlock it I'll just recover it to factory settings, we'll see if that helps, but I don't like the sound of that.
What apps are -you- installing?
Launchers and power management apps are prime suspects...
Otherwise, mobo failure. It may be firmware but how far do you want to take it?
It should run fine out of the box.
Last time I played with launchers was with good old SGS about 5 years ago, only app out of ordinary was AccuBattery to check that SoT drain, but could it make such a damage without root privilages?

Accubattery isn't the culprit...
