Procedure 3
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
PJ8800 DC IN 15 V 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 input port where an AC adaptor’s DC output plug is
connected is firmly secured to the system board.
•
If the DC IN input port is loose, go to Procedure 5.
•
If it is not loose, 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
Make sure the battery pack is installed in the computer correctly. If the battery is
properly installed and the battery icon still does not light, go to Procedure 4.
