When you say the screen went crazy I'm guessing you mean filled with static and wavy lines. Please correct me if I'm wrong.
If that's what you're experiencing, I had the exact same issue, but it occurred when I drained the battery to 0% while it was plugged in to my computer. Apparently, the USB ports on most computers don't provide enough juice to keep the N7 alive while using it. I just long-pressed the power button (for around 30 seconds) after it had charged for a bit and the N7 booted right up.
I solved the problem by charging the N7 from a wall socket (and not from a USB port on a computer) when I want to use it while it's charging.

Yes, that what I experience, yeah'wall socket helps but if u run something right after it just boot up, than the lines will dance again^^

If you kill the battery that far dead you need to let it charge 20 or 30 minutes if you're having issues like that.
I understand whats happening now.
OP, if you're going to use the computer and you completely drain it like that, let it charge a bit before you power it back up. Its apparently a habit, and I just don't think its a good thing to kill it dead, connect it to a power source and then immediately kill it again by drawing way more power than we have.

Odd battery-Not your usual drainage :D

Hey guys,I have seen some things with my GS2's battery that aren't exactly what you'd call normal.Let me explain:
Today,I plugged my phone it at about 45% battery for some minutes(I was gonna be away from home for a long time,so I wanted some extra unneeded juice) and unplugged it just before I left the house at 58%.I was en route to the bus station when I checked the time(I was late as always! ) to see I had 59% battery.After some twenty minutes,when I reached my destination,I took my phone out of my pocket to make a call just to see that my battery was at 61%! After that all was normal.
This was the third time I experienced something like that.First time was more impressive.I went to the cinema with 38% battery and left with 50%!All without plugging the phone anywhere!
Now,I know I shouldn't be complaining about something like that,but something must be wrong here.If everything wrong was like that I'd be a happier man,but just sayin'.
Any ideas?Or is my phone unique in that aspect?
Sounds like bad calibration to me. Let the battery drain till the phone turns itself off, then charge it (while off) till full.

Me wants . With that said its probably bad calibration

Definitely calibration problems here. The screenshot below explains what happened with my SGS2. This was the first charge out of the box. Plugged it in and at first, the charge went up steadily. Then, BOOM, 100%. Disconnected charger, and after some time noticed phone was off - battery was at 0% in under 2 minutes.
It's OK now. I'm getting 2+ days of use on a single charge.
same here. my battery-percentage also raised once while using the unplugged phone. then I turned it off and charged it. since then everything is fine.
Too bad.I thought I was like the guy from Infamous or something!
Thanks for your replies guys.Will callibrate and report.Although the Android OS drainage persists still...

The charge level on my SGS2 is going up as I am typing this. It is not connected to anything.

[Q] Help! 5 beeps..

Hello community, please help:
I've been getting 5 beeps, which drop in volume, whenever i play a certain game (Plague inc.). A temp monitor shows only 80*F. It is rooted w/ SmoothROM 4.2. One time, it did the 5beep cycle and i kept playing, and the screen looked like I pulled the electrical plug on an old school tv(Zap! then power off). Now, i sometimes will see very fast horizontal line glitches while doing any task on it. I've tried to search but couldn't find anything Nexus 7 specific. Also, couldn't find what 5 beeps in decreasing volume meant in the Nexus 7 guidebook. I really dont wanna fry my first tablet
Thank you!!!

Hmmmmm I've never heard of that. It sounds like your GPU could be overheating and rebooting for safety. Do you have it oc'ed or anything?

i think i read someone else having this prob and your right it came down to overheating, also check your battery status's to see if the power droped from say 70-20% i think i remember that was a symptom the over guy had and also the visual lines after.
srry not much help thou

Tablet bricked itself?

Bought a refurbed 32GB WiFi from sears on Jan 2nd and had no issues except for a screen flicker. I was running a CM10.1 build from around Jan 26th and the latest Motley Kernel.
Yesterday I was using the tablet as usual, but I hadn't charged it in a couple of days
so the battery was getting low. After I got home from work I went to use it but the screen wouldn't come on. I figured the battery had died so I went to charge it, but I never got the powered down battery animation. I've tried holding down all 3 buttons for at least a minute and nothing is happening, and when I connect to my computer I get a USB not recognized error.
I have about one day to return the device to sears with the 30 day warranty, but I just thought I'd check to see if anyone else was able to resolve a similar issue before I do so that I don't lose all of my data, and the fact that if they do get it running again that its rooted and running CM.
Any suggestions, or should I just take it back?

AW: Tablet bricked itself?
One thing I learned from here, is that I never ever should let the nexus 7 run out of juice. Seems to be a death sign..
Jup, take it back.
Sent from my Nexus 7 using xda premium
Not a death sign.
You just need to let it sit on the charger for about 1/2hr, then it should boot right up. People panic when the device doesn't respond or screens start flashing, but it won't boot and they start mashing buttons and posting about their 'I think I bricked my device'. After a device has run down it might take a long press of the power button to get it to boot and/or sit on the charger for a bit.
Running the battery down should not be confused with the Sleep Of Death (SOD). The fix for an SOD is also a long press of the power button.

try connect to charger at least a half an hour, then press just power button for 1 minute. i had similiar issue, and it worked for me. if dont work, maybe you got battery connector loose problem. try search in general section about that.

I think my N10 just died.......

Hi All,
I was browsing the web a couple of hours ago and my N10's screen started flashing on/off and after around 10secs the thing crashed/turned itself off. Being an N10 this was not an unusual event! However when I try to turn it back on nothing happens. I can hold the power button / power button with volume buttons pressed and nothing happens. If I plug it in to charge I do not get even get a charging icon.
If it makes any difference I was running the latest Rasaber with Franco's r11 kernel and I know I had at least 40% battery left when it died. I have left it plugged in to the stock charger for around an hour hoping that something might happen but still nothing.
Has anyone ever experienced anything like this?
There was not a sad enough looking Emoticon to convey my sadness over the possibility my lovely Manta is dead......
no man ... it s impossible . nexus 10 its the best device ever . acording to some gurus here
your device its dead . now you have to stay on your knees to google replace it . good luck

Something similar happened to me but I'm totally stock. I Googled and the solution was to recharge the unit via my PC USB instead of plugging it into an outlet. I have no idea what happened but after a few hours of being connected to my PC it was back and working. Hope that helps.
I'm running the same rom and kernel combo. No problems or anything weird happened. It must be hardware related.
Did you try the holding-the-power-button-for-a-minute routine?
I would try to leave it plugged in on the charger for a while and see if it gets fixed. That usually solves all sorts of "wont turn on" problems

Sent from my Nexus 10 using xda app-developers app
is it possible for the tablet to get overheated?
I have had that happen on stock.
My theory: it is linked to the 'battery status not updating'-bug. Your Nexus thinks the tank is still half full, while in fact you are running on fumes. It does not realize this, so no dimming of screen, no low power warning, it just goes full steam ahead, until the battery is totally and utterly and completely depleted.
Then, obviously, it won't start but it will also have trouble charging. You need to charge it for quite some time, sometimes try a different charger, and sometimes keep the power button depressed for a full minute for it to come back to life.
Now when I use my Nexus, I keep an eye on the battery status. If it does not go down, I know I need to reboot for the battery status to be read properly again. It is a bit of a bother, but not too much. The bug only kicks in after the tab has been lying around for a while sleeping. So if I want to watch a movie, I first reboot. As long as I keep using the tab (i.e.watching the movie), the bug won't 'activate' and the tab will shut off properly when it senses the battery is low, in stead of continuing and deep depleting the battery.

[Q] Tablet bricked by USB OTG

Hey guys,
Well I screwed up and I think the only thing to ask is whether this situation is covered by warranty.
Yesterday I received my new USB OTG cable, because the other one stopped working as soon as you would turn it a little. I tested it with a mouse yesterday and it was running flawlessly. Today, I wanted to test whether it would be able to mount USB sticks, so I took the nearest one and plugged it in. The screen was locked, and after nothing happened I tried to unlock the screen, which wouldn't work. The rest is history and a lot of confusion and anger.
The problem might have been that it was a bootable USB stick containing Ubuntu 13.04, but I'm heavily doubting that this caused a brick. I mean, just plugging a USB stick in cannot brick a tablet? Wubi is an .exe-file an AFAIK Android cannot do anything with this by itself.
I was running PA 3.98/stock kernel and didn't have any program like stickmount installed. I cannot access the bootloader, charging the tablet gives no response at all and when I try to connect it to the computer, it just says that it cannot recognize the device.
Thanks in advance :crying:
Hmm, anyone? I guess I'll ask it in the Ubuntu forums tomorrow too.

Have you tried holding down the power button for 20-30 seconds to force a reboot? Is it possible it is suffering from the low battery bug? By that I mean is it possible it had a low battery or it thinks it had a low battery and freaked out?

Just wow, this really worked.
I feel so retarded now, I already tried holding down power for a while but nothing happened. Guess I was kind of freaking out and couldn't think straight anymore.
Could you tell me more about this low batt bug? Because my tablet was at 1% when it just booted and it was around 40-50 when it gave up.

Glad I could help, sometimes it's the simple stuff that gets overlooked in moments of panic. There is a sticky in this section and other posts as well regarding the battery bug.
http://forum.xda-developers.com/showthread.php?t=2090826
I guess most of the panic came from the coincidence that it shut down at the exact moment of connecting a bootable USB using a new USB OTG cable gehehe.
