Screen suddenly went black, won't respond

mcpu — Wed, 24 Jun 2015 02:14:39 GMT

I was playing a game on my phone while the phone was charging. Granted, my phone was sitting at 1% while it was charging and it wasn't moving above 1% while I was playing the game, which isn't unusual since the game was draining a lot of energy. Suddenly my phone screen just goes black with no backlight. It didn't shut down gracefully like it usually does when it's at 1% (powering off status screen appears before it shuts down).

I tried hitting the power button a few times and no response. I tried holding down the power button and there was no response. I tried doing a reset by holding the power button and the up volume button together, but it still didn't respond. Mind you, I tried this both when I had my phone plugged in to the wall charger as well as when it was disconnected.

Any ideas of what may have happened or what I should try next? I think it may have to do with the fact that my battery was running at 1%, might I have completely drained the battery? I'm currently leaving my phone alone and leaving it plugged into the wall charger. I don't want to lose any information on my phone as I have a lot of important documents that I have yet to back up so a factory reset isn't something I want to do.

Connect the phone to a wall charger, press and hold power and volume up for 10 seconds, let it charge for two to three hours, then repair it with PCC

Running the software repair on PC Companion:

Hi all,

I left it alone to charge for about 1.5 hours. I changed the usb cord afterwards (since it was an old one and was being held together with electrical tape in a few places), I did a soft reset (held down the power button and the volume button) and it vibrated 3 times meaning it still has life. I gave it another 1/2 an hour to charge and I got it back up and running again.

I think the problem was I drained the battery past 1% and it needed time to get a charge back to at least 1% again before it could become responsive again. All is well though. Definitely making a back up of everything tonight just in case.
