Verify that the exterior of the computer is free of any obvious physical damage. 4. If the computer is operating from an AC adapter, verify the following: • The AC adapter’s AC power cable is connected to the AC adapter and the power source. • The AC adapter’s DC power cable is properly connected to the computer’s DC power input connector. • The AC adapter and cables are free of any obvious physical damage. NOTE: If the charging indicator and low-battery indicator flash continuously while the computer is connected to AC power, disconnect the computer from AC power and move it to a cooler location. When the computer has cooled to room temperature, reconnect it to AC power and continue charging the battery. If the computer is not allowed to cool, the battery stops charging before it reaches full capacity. 2-2 Dell Latitude XPi CD Service Manual 5.
