Xperia M turning off..

[MichalWolff]

My xperia m is turning off and I can't turn it on. When the screen goes black it doesn't react to pressing the power button. I have to take out the battery and wait a few minutes to turn it on again. Does anybody know what to do???

Charge your phone for 30min or so (wall charger not a computer) > repair your phone with SUS or PCC

Update Service (SUS)

PC Companion (PCC)

Bridge (for Mac)

 for future reference

Did it, and it doesn't help, still the same...

You will have to take it to a Sony repair center
