I have same problem with Samsung A800 which only switches on when i plug in the charger & at the same time it shows battery full charged.
But when i unplugged the charger, it shutdown the phone. What is the problem? is it software or hardware?
I also encounter such think with T100 before but i just suck it into the spirit & brush & heat it. and it works.
But did the same thing with the A800 but no progress.
help if possible with tutorial or links.
Thanks.
