PWR-LED: Power/Standby LED
When the system’s power is on, this LED will light. When the system
is in the S1 (POS - Power On Suspend) state, it will blink every
second. When the system is in the S3 (STR - Suspend To RAM)
state, it will blink every second.
Note:
If a system did not boot-up and the Power/Standby LED did
not light after it was powered-on, it may indicate that the CPU
or memor y module was not installed properly. Please make
sure they are properly inserted into their corresponding socket.
