I expirienced the same problem when I bought a second hand unit from a friend. He didn't discharge/charge the batteries according to the manual so I tried to get the batteries back to live without any luck. After approx. 2 minutes this discharge/charge cycle would stop without any warning.

Thats how i tested and solved the problem:
I went back to firmware v1.05(eu) by burning the firmware on a cd-rw with
UltraISO, Write Speed 10x and Disc-At-One (DAO) mode and flashed the player with firmware v1.05(eu). To my surprise the discharge/charge mode worked with this firmware (original firmware) perfectly !
So I burned firmware v1.81(eu) the same way as I did v1.05(eu), flashed the player with firmware v1.81(eu) and to my surprice the discharge/charge mode is working perfectly !

(This issue is a firmware problem and not a battery problem and does mislead easely, beacause I also thougt, that my batteries are faulty)

I presume that my friend did not update to firmware v1.81 properly to be more precise I guess the burning speed could be an important part of this process (don't burn with maximum speed).

I would like to thank all members for their contributions and make this forum so valuable to all iRiver enthusiasts.

Good luck to all
