LED blinking after BIOS update
Hello !
I have question about BIOS update on Dell Precision 7530. I have searched similar problems, but found nothing.
I received Windows update (I am using Windows 10 22H2) few days ago with BIOS update included. During rebooting I saw that my BIOS is updating. Then, OS started as usual, but diagnostic LED started to blink (1 white, 2 amber). Current installed BIOS version is 1.34.0.
I checked documentation and found that LED is indicating CPU failure, but system is still working. Also, diagnostic led had never blinking before this update.
Can it be related to BIOS update ?
I will apppreciate any help.
Thanks!

Reset hardware by removing battery and power, press and hold power button for 30 seconds. Reconnecting battery and power. Test again.
Reset BIOS to default settings. Test again.
Note that version 1.34.0 may not allow to downgrade.

@Chino de Oro Thank you! The approach with removing and reconnecting the battery has solved the problem
