Procedure 2 Battery LED Indicator Check
The Battery LED indicator shows the battery charging status. The LED, identified by a
battery icon on the front of the computer, glows orange when the AC adapter is charging the
computer's battery pack.
If the Battery LED indicator glows green, the AC adapter is connected and the battery
is fully charged.
If the indicator glows orange, the AC adapter is connected and the battery is being
charged.
If the indicator does not glow, go to Check 1.
Check 1 Make sure the AC adapter's cable and AC cord are firmly plugged into the DC IN
socket and wall outlet. If these cables are connected correctly, go to Check 2.
Check 2 Make sure the battery pack is installed in the computer correctly. If it is, go to
Check 3.
Check 3 Remove the battery pack and check that the battery terminal is clean and not bent.
If the terminal appears dirty, clean it gently with a cotton swab dipped in
alcohol.
If the terminal looks bent or damaged, replace the lower system board.
If the battery terminal is clean and not bent, go to Check 4.
Check 4 Connect a new AC adapter. If the Battery LED indicator still does not glow, go
to Check 5.
