DISSEMBLING AND ADAPTER CHECKING

HOW TO CHECK THE AC ADAPTER
You are here because the computer fails only when the AC adapter is used.

• If the computer does not charge during operation, go to “Checking operational charging”.
To check the AC adapter, follow the steps below:
1. Unplug the AC adapter cable from the computer.
2. Measure the output voltage at the plug of the AC adapter cable. See the following Fig

Note: Output voltage for the AC adapter pin No. 2 may differ from the one you
are servicing.
3. If the voltage is not correct, replace the AC adapter.
4. If the voltage is acceptable, do the following:
