Disconnect the AC power cord/cable and remove the
main battery pack. See “Changing the main battery” on

live wall outlet for several hours with the computer turned
off. After that, the main battery will be completely charged
and ready to power the computer.

computer is turned off, even when AC power is attached.
The RTC battery charges when the computer is powered on.
