other nonconducting stylus to press and release the Power button on the server front panel.
When main power is applied to the full server, the Power/OK LED next to the Power button
blinks intermittently till BIOS post finishes.
If the problem with the server is not evident, you can try viewing the power-on self test (POST)
messages and BIOS event logs during system startup.
