led blink

[venugopal]

I have xperia m dual, in my mobile after battery empty, I put charge but not charging, instead of I see led indication blinking in the combination of white and pink. What does it means, is there any problem in mobile.

Connect your phone to a wall charger > press and hold power & volume up for 10 seconds > let your phone charging for 2 hours then try to turn it back on
