If the voltage is within the range, do the following:
v Replace the system board.
v If the problem is not corrected, go to “Undetermined
Problems” on page 25.

always indicate a defective adapter.
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 the next
section.
Checking the Battery ASM
Do the following:
1. Power off the computer.
2. Remove the battery ASM and measure the voltage
between battery terminals 1 (+) and 5 (-). See the
following figure:
Note: Signal lines, not used in these steps, are used
for communications between the system and the
battery.
