HPE DL380 gen10 all LED flashing when the power is on

[Riadm13]

Good morning,
Yesterday we had to turn off our IT platform and cut off all the electricity, I turned off the servers normally, and today when I turned on the electricity and turned on the IT platform, all the servers were normal except one, it's an HPE DL380 GEN 10, all the LEDs flashed as shown in the photo below

Then when I pressed the power button, just this button started flashing, but the server did not start, so I connected to the ilo and clicked the mementary press button three or four times and then the server started but this message appeared

The ilo  date time become 2001

iLO Date/Time

Mon Jan 1 00:31:47 2001

And in the integrated management log :

Non-Volatile Memory Corruption Detected. Configuration settings restored to defaults. If enabled, Secure Boot security settings may be lost.

Initial Update 01/01/2001 00:00:41 Event Class 0xA Event Code 0x266

Please what is the problem ? and how can I solve this ? because I need to be carefull it is the prod server.

Thank you

Hi @Riadm13,

Good day!

Looks like the BIOS settings been restored automatically.

Could you please try to clearn NVRAM physically and check.

Also you may try Minimum Configuration (using Single processor and single DIMM)

Later try to add the components one-by-one and isolate if it's happening because of any particular component.

If nothing helps, and if iLO is accessible, try to use Redundant ROM using the option mentioned on the Pic : 

If nothing helps here, you may have to replace the System Board.

Thank you, I'll try it and tell you if it works.

Please just one more question, if I change the CMOS battery would it affect the BIOS and booting configuration ?

Hi @Riadm13,

Good day!

Yes, it would delete / clear the Settings and configurations.

Thank you
