Procedure 1 Power LED Indicator Check
The AC adapter converts AC to DC power and contains a charging circuit for charging the
batteries. The adapter connects to the Power socket connector on the back side of the com-
puter. When the AC adapter is connected and power is off, the AC adapter charges the
batteries.
The Power LED displays whether or not the AC adapter is connected and supplying power.
When the Power LED is green, the AC adapter is connected and supplying power to
the computer.
If the Power LED does not light, the AC adapter is not supplying power to the com-
puter or the AC adapter is not attached to the computer, go to Check 1.
If the Power LED is flashing orange, the AC adapter voltage supply is abnormal or the
power supply is not functioning properly, go to Check 2.
If any of the above indicator conditions are abnormal, make sure the Power LED indicator
lights are not burned out before performing the following checks:
Check 1 Make sure the correct AC adapter cable is firmly plugged into the Power socket
on the back of the computer.
Check 2 If the Power LED flashes orange when the AC adapter is connected, its voltage
output is abnormal. Connect a new AC adapter and turn the computer on again to
verify the indicator condition. If the problem still exists, perform Check 3.
Check 3 The battery pack may be malfunctioning. Replace the battery pack with a new one
and turn the computer on again. If the problem persists, perform Check 4.
Check 4 Place the computer in an environment between –20°C and 70°C until at ambient
temperature. Repeat the steps which caused abnormal operation. If the same
problem persists, perform Procedure 3.
