PB Ti won't wake?

When my PB Ti is in sleep mode and then runs out of battery power and I then try to wake it, it won't wake up even when I plug in the AC power. It will only respond to a Force Restart and on AC power.

Is this a OS or Ti problem or my specific computer?

System: PB G4 Ti running OS 10.2.3

Thanks for any info.

I don't think it's any kind of problem. The battery is what maintains power during sleep. If you run out of battery power, there is no power to maintain sleep. Therefore the computer does an emergency shutdown. m.
