I have the lt30p and last week I attached it to my PC to do my backup. Halfway through we had a power cut and when I restarted my computer PC companion flashed up something about having to remove the battery. I have left it on charge for over 24 hrs, I have tried hard reset, everything I can see online still nothing. When I push the power button the light flashes green once, the Sony emblem flashes up and then disappears again. If I press per+vol up the phone will vibrate once then 3 times but again nothing, assistance greatly appreciated
