BIOS corrupted when upgrading BIOS for HP i17 Zbook G1/G2, without human intervention or interruption during installation. Now, when restarting the screen is black, the fan does not turn on and only 2 LEDs blink 7-8 times. Does anyone know a solution to revert to the old BIOS?

Hello.

 

The LED blink codes are listed on a HP Support Document:

HP Notebook PCs - Computer beeps or a light blinks during startup | HP® Support

 

G1 and G2 are different models with different BIOS upgrades.
