Xperia S can't start up

[SilenceWhisper]

I can't start up my xperia s no matter how long I click the power button and any button I could press.
When I connect to charger , the notification light did light up ( red / orange ).. But phone won't start up ... Even after whole day of charging ... Help ~ thanks.

You could try replacing the battery and see if that helps.

I have the exact same problem!!

My phone suddenly turned off and no matter what I do it doesn't turn on. I didn't try to flash my phone or anything, it just "died" on it's own. PLS HELP!!!!

Connect the phone to a wall charger > press and hold power & volume up for 10 seconds > let it charge for 2-3 hours
