My brother has a Nabi 2, and it was running fine for a while, but now everything's gone weird. It woun't boot up, and the screen only stays black, with nothing else on it. So first, we found that the Nabi was indicating that we needed a new charger, so he bought one. But it's been charging for a really long time, and there is still a black screen when you try to turn it on. I had rooted it, and I haven't messed with anything since. It has been stable for a couple months before this happened. If you go to turn it on while it's plugged in, the charging LED will change to green for a second, then switch back to red. The weird part is, this only happens if you hold down the power for 10 seconds or so, as if you are turning it off. I realize this isn't a common tablet, but I'm hoping there's something that anyone knows that will help my little brother.

So I'm having a really strange problem, and it seems like the phone is completely dead. This may be unrelated, but about 5 or so days ago, my camera stopped working, and in the week before the failure, it would make a clicking noise whenever I used it. Last night however, I woke up to my phone rebooting itself over and over. I didn't know what the problem was, and didn't want to deal with it, so I pulled the battery out (not while it was booting). This morning, when I woke up I could not get the phone to turn back on. I tried two different batteries, tried each alone, and each plugged in to AC as well. No response from the power button at all, nothing on the screen, no green LED flash, nothing. Heres the odd part: If I take the battery out, and plug it in to my PC, the green LED turns on, yet, the power button still does nothing.

same thing with my phone.. been looking for answers.. but nothing... did you find solution for this??
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..
Hello!
Earlier tonight I received a text message and then my phone died - I knew the battery was nearly dead.
When I plugged it in, nothing happened - no orange LED like usual.
I let it sit for a while and still nothing.
Eventually I pulled the battery and put it back in and still won't power on.
Pulled the battery again (left it out), left the back cover off, and then plugged in the power.
After about 2 seconds the orange LED comes on for about 4 seconds and then turns off <---I've not seen any other posts mention this.
The phone will not boot still though - tried holding down power for 60 seconds, and even tried in conjunction with volume up and volume down.
The screen remains black, no vibration, no HTC logo .. nothing.
My wife has the same phone, so I put her battery in mine and it still will not boot.
My phone is NOT rooted or modified in any way (using stock VzW rom)
The screen is cracked but it's been that way for months and I've had an Otterbox on it ever since (go figure .. should have had one before it got broken). It's been working fine. It has not gotten wet today, or been sat on, or dropped or even looked at funny.
The phone is out of warranty and I do not have VzW accidental coverage.
Are there any more tricks to try, or should I go to the store tomorrow?
Thanks!
I am going to plug it into the computer and see if ADB will see it, but my assumption is no.
I'm thinking maybe the processor died... ???
I know if a PC processor dies then nothing happens when trying to boot .. no post beep or video.

Try charging the battery on your wifes phone then turning yours on and see if it works if the processors dead like you assume then well R.I.P Rezzy if you call verizon they will tell you to do a factory reset from the recovery maybe you could try that
Hey, i am new to xda, so i don't really know if this is the right category for this thread.
I am running Slimbean: Slim-i9300-4.3.build.2-OFFICIAL-1322 (the newest stable version)
And i have dropped my phone several times, so my screen is broken and gone over the back button (it still works).
Anyways, i dropped today AGAIN out of my pocket, in a car, when i was about to shut the door, so the phone was smashed by the door. The screen didn't crack more then it already is, but it shut down, and now i cannot start it. I figured it was becouse it ran out of battery (i only had like 2-1% when this happened), so i plugged in my charger, and nothing happens.
Usually when i plug it in when the phone is dead, i get this grey battery icon on the screen wich freezes, but it works.
Now nothing happens, and when i try to start it, nothing happens except the little red motion sensor thing is blinking red once in like 5 secs.
Do i need to buy a new battery? Please help!
P.S. I know i'm not very good at english, but please help!

EDIT: When i plugged my charger in and let it charge for like 15 mins, the LED starts showing yellow (wich means it's 15%+ but not done charging).
And nothing happens when i tried to wake it up. But when i held the power button for like 3-4 secs, the yellow light disappears. It does not vibrate or anything that it use too.

Hi there
I have used this tablet without bigger problems for months. a few days ago I've turned it on and after a few minutes using it the device froze completely. then the screen turned black after a few seconds, power led off. I've tried to reset it by pressing power button long and nothing happens, display black, led off.
Everytime I plug it in, the power led turns on, but nothing else happens.
Today I've opened the device and found out the batteries are at 2.8V. I've then charged them with my Lipo charger (had to desolder it, charge and then resolder). Still nothing works. And if there's no battery connected the exact same happens like with the batteries in place: nothing exept green led turns on.
So, why did this happen and how can it be fixed?
Thanks
same thing happened
hi,
exactly the same thing happened to me. Did you manage to solve the problem?
I also tried to empty the batteries and then to re-start, no success. The LED will light for a couple of minutes then turns off, but nothing else happens afterwards, the screen remains black all the time.
Resetting the device also doesn't work, the screen won't turn on, not even in the recovery mode.
I would appreciate any help on this issue.
ori
still dead
Nope, unfortunately I could never fix it so it's just laying around collecting dust as a expensive paperweight...
