Chapter 5 Power management
If you plan to leave the computer unattended during the discharge, save your information
before 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 does not shut down automatically.
◦
The hard drive speed does not decrease automatically when the computer is idle.
◦
System-initiated Hibernation does not occur.
Connect the computer to external power until the battery is fully recharged.
The computer can be used while the battery is recharging, but the battery charges faster if
the computer is off.
If the computer is off, turn it on when the battery is fully charged.
