gil64,
This player should not do that.
It sounds like faulty hardware .
Can you return it to seller?
If not please see link below. You may need to disassemble, and short out player to' adfu ' mode (recovery mode) .

It almost sounds like a bad soldering job at the switch/ or battery. Not a FW problem.
Let us know how you get on....
