Procedure 1 Power Cord Check
The T6600C's power cord carries AC voltage to the power supply unit from a wall outlet.
Check 1 Turn off the power, make sure the power cord is firmly plugged into the AC IN
socket and into a working wall outlet. If the power cord is connected correctly,
go to Check 2.
Check 2 Disconnect the power cord from the T6600C. Use a multimeter to check the
output voltage from the wall outlet on the power cord.
If the output voltage is not correct, replace the power cord with a new one. If
output voltage is correct, perform Procedure 2.
Procedure 2 Connector Check
The power supply cables should be connected to the system board. These cables may be
disconnected or damaged. Open the keyboard cable cover following the steps described in
Chapter 4 to check the power supply cable connection to the system board.
Check 1 Remove the keyboard cable cover. Make sure the power supply cables are con-
nected to the system board.
If these cables are disconnected, connect them to the system board. If these cables
are damaged, replace the power supply unit.
If these cables are OK, perform Procedure 3.
