Z2 Tablet dead after Lollipop and full discharge. PC won't detect

Victoramb01 — Sun, 10 May 2015 01:26:30 GMT

Hi.

I updated the software to Lollipop a couple of weeks ago. Had not drained the battery fully since. Three days ago I was gaming on it and got it down to below 5%. I left the tablet on for the rest of the day and found it off at night.

I left it charging overnight, but it has not come back on after that. I've tried the up/down volume combination, pinching the orange button near the Micro SD slot, leaving it charging for over a day. Nothing works.

I called the support team and they instructed me to install Sony PC Companion to do a software Update, but the PC can't even detect the Tablet.

The tablet red charging led lights up when I plug in either the charger or the PC, but nothing beyond that.

I'm looking for some more help/instructions/directions. I'm an advanced computer user and can follow advanced instructions if needed.

Thanks,

Victor.

Connect the tablet to a wall charger > press and hold power & volume up for 10 seconds > let it charge for 3 hours > even if it doesn't seem to be working.

Sorry. No response. I did it a few times today, left it charge for a few more hours.

I'm getting suggestions and advise telling me that the battery is below a certain threashold and the system won't let it charge. That the fix is to actually jumpstart the battery outside of the tablet. I could take the tablet to a local technician, but I'm worried about loosing the water seal. Any ideas?

It's better if you contact your local Xperia Care

that batteries on the new smartphones and tablets should never go bellow 20% of charge, anw, you need to plug it into the wall charger and let it for 30 minutes, then hold vol up+powr to invoke a snapdragon hot reboot and it should start
