Phone is dead

[JakeMorris19]

I was using my phone(sony xperia T) , it was on charge. I put it down for literally a few minutes, when  went i to pick it up again the whole scree was blue. It then shut off, it now wont respnd, no led light, no nothing. I've tried every reset solution I can possbly find and there is completely no response at all

Press and hold on/off button and volume up button at the same time until the phone vibrates. Charge the phone a couple of hours and try the same again. 

If the problem still persists you can try to repair the phone software using PC Companion: 

http://www.sonymobile.com/update

In PC Companion, press start on Support Zone > Start on Update the phones software > Press the blue link that says "Repair phone". To all this without the phone connected to the PC.

I'm not sure if this will help, but here goes anyway. Within the last 2 mths I have had 2 xperia T's unexplainably quit I mean

nothing, wouldn't power up. woudn't charge absolutley nothing. I returned the first one and got a replacement, the second

one I took to a repair guy, because as you well know you can't get the back off toget at the battery. Any he disconected the

battery for a while, put it back together and everything is fine now???
