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

5. Power off the computer.
6. Disconnect the AC Adapter and install the charged
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

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:
