Check 2 In the case of error code 10h or 12h:

Make sure the AC adaptor cord and AC power cord are firmly plugged into the DC IN 15 V socket and wall outlet. If the cables are connected correctly, go to the following step:

Connect a new AC adaptor and/or AC power cord, if necessary. If the error still exists, go to Procedure 5.
