Procedure 7
The purpose of this procedure is to determine if the system board is providing the appropriate
voltages to the Power/Sleep LED. To perform this procedure, perform the following check.
Check Measure the voltages between pins 18 and 20 at J10K1 (Power/Sleep LED
connector) on the system board when the system is turned on but not in Sleep
mode.
If the voltage remains constant at 5VDC, perform Procedure 8. If the voltage does
not remain constant at 5VDC, perform Procedure 13.
Procedure 8
The purpose of this procedure is to determine if the Power/Sleep LED is defective. To
perform this procedure, perform the following Check.
Check (A) Replace the Power/Sleep LED. (B) Test to determine if the problem still
