hi..... thank for the answer... i really appreciate it...
yesterday i borrow my friend desktop charger for nokia bl-5b and charged the battery until full, and then i place it in my mp4 player and turn it on... but it always say LowPower....
really confused here.....
the problem is when i used the power from battery it always say lowpower but if i used power from usb or adaptor it seem fine and i have no problem to transfer file from my computer.....
there is friend that say that maybe the problem is at switching diode.... but i don't know where this diode located and what i must to do with it....
really confused here......
