Connection Check
The power supply wiring diagram is shown below:
Any of the connectors may be disconnected. Perform Check 1.
Check 1
Disconnect the AC power cord from the wall outlet. Check the power cable for
breaks. If the power cord is damaged, connect a new AC power cord. If there is
no damage, go to Check 2.
Check 2
Make sure the AC adaptor cord and AC power cord are firmly plugged into the
DC-IN jack socket and AC adaptor inlet/wall outlet, respectively. If these cables
are connected correctly, go to Check 3.
Check 3
Make sure the DC IN jack is firmly connected to the connector CN8800 on the
system board.
•
If the DC IN jack is not firmly connected, go to Procedure 5.

If it is connected, go to Check 4.
Check 4
Use a multimeter to make sure the AC adaptor output voltage is close to 15 V. If
the output is several percent lower than 15 V, go to Check 5. If the output is close
to 15 V, go to Check 6.
Check 5
Connect a new AC adaptor or AC power cord.
•
If the DC IN icon does not light, go to Procedure 5.

If the battery icon does not light, go to Check 6.
Check 6

properly installed and the battery icon still does not light, go to Procedure 4.
