To verify the symptom of the power problem on the com-

puter, do the following:

1. Power off the computer.

2. Remove the battery pack.

3. Connect the AC Adapter.

4. Check that power is supplied when you power on the

computer.

5. Power off the computer.

6. Disconnect the AC Adapter and install the charged

battery pack.

7. Check that power is supplied by the battery pack

when you power on the computer.

If you suspect a power problem, refer the appropriate

power supply check listed below:

 “Checking the AC Adapter”

 “Checking operational charging” on page 31

 “Checking the Battery ASM” on page 31

Checking the AC Adapter: You care here

because the computer fails only when the AC Adapter is

used:

 If the power-on indicator does not turn on, check the

power cord of the AC Adapter for correct continuity

and installation.

 If the operational charge does not work, go to

“Checking operational charging” on page 31.

Unplug the AC Adapter cable from the computer and

measure the output voltage at the plug of the AC Adapter

cable. See the following figure:
