5. If the issue is still observed or without power button LED lit on, implement the minimum configuration to
check whether any specific components have locked the power permission. Replace power supply units
and check the power button function after installing each unit.
6. If all procedures are tried and the issue cannot be resolved, collect the failure information with system
logs captured and contact Lenovo Support.
Server does not power on
Complete the following steps until the problem is resolved:
1. Check the event logs for any events related to the server not powering on.
2. Check for any LEDs that are blinking amber or yellow.
3. Check the system status LED on the system board (system board assembly). See
“LEDs on the system
board assembly” on page 458
.
4. Check if the power input status LED is off or the yellow LED is lit on the power supply unit.
5. Do the AC cycle to the system, that is, power off the power supply units and re-power them on.
6. Remove the CMOS battery for at least ten seconds, then, reinstall the CMOS battery.
7. Try to power on the system by IPMI command through XCC or by the power button.
8. Implement the minimum configuration (one processor, one DIMM and one PSU without any adapter or
any drive installed).
9. Reseat all power supply units and make sure that the power input status LED on the power supply unit is
lit.
10. Replace power supply units and check the power button function after installing each unit.
11. If the issue cannot be resolved by all attempts above, call service to review the issue symptoms and see
whether the system board (system board assembly) replacement is necessary.
Server does not power off
Complete the following steps until the problem is resolved:
1. Determine whether you are using an Advanced Configuration and Power Interface (ACPI) or a non-ACPI
operating system. If you are using a non-ACPI operating system, complete the following steps:
a. Press Ctrl+Alt+Delete.
b. Turn off the server by pressing the power button on the front operator panel and holding it down for 5
seconds.
c. Restart the server.
d. If the server fails POST and the power-control button does not work, disconnect the power cord for
20 seconds; then, reconnect the power cord and restart the server.
2. If the problem remains or if you are using an ACPI-aware operating system, suspect the system board
(system board assembly).
Power problems
