Checking the Operational Charging
To check operational charging, use a discharged battery pack (battery Asm) or a battery Asm
that has less than 50% of the total power remaining when installed in the computer.
Perform operational charging. If the battery status indicator does not turn on,
remove the battery Asm and let it return to room temperature. Reinstall the battery Asm.
If the charge indicator still does not turn on, replace the battery Asm.
If the charge indicator still does not turn on, replace the system board. Then reinstall the battery Asm.
If the reinstalled battery Asm is not charged, go to Checking the Battery Asm'.
