Hi, I don't know the answer to your problem, but I would advice you to be careful not to get totally discharged the backup battery, you can loose all your data!
BTW, did you check the charge of your main battery before and after playing?? if it is too low, the machine takes energy from the backup battery, therefore you must recharge your main battery before you get the backup battery discharge
(or connect to AC power
) and you must put a new backup battery.
Well, sorry if I'm too obvious, guys here in HPC can help you to discover more profound issues
