I just put it on a charge and the phone stop displaying it off it ons
My phone on a charge switch it self off and the red led light will be blinking but the phone will not on
I had the same problem. solved it by getting a Z10 docking station.
Take the battery out of the phone and charge it on the docking station for a few hours.
docking station must be a dual station. Like this one...
Another option is to buy a new battery
