beginning the discharge procedure.
●
If you use the computer occasionally during the discharge procedure and have set energy-saving
timeouts, expect the following performance from the system during the discharge process:
◦
The monitor will not turn off automatically.
◦
Hard drive speed will not decrease automatically when the computer is idle.
◦
System-initiated Hibernation will not occur.
