no damage, go to Check 2.

Make sure the AC adaptor cord and AC power cord are firmly plugged into the 
DC-IN socket, AC adaptor inlet and wall outlet. If these cables are connected 
correctly, go to Check 3.

Use a multi-meter to make sure that the AC adaptor output voltage is close to 19 
V.  If the output is several percent lower than 19 V, go to Check 5.  If the output 
is close to 19 V, go to Check 6.
