Hi, I have HP Probook 450 G7 with no display.
All voltages present, so I think the problem is bios.
Can someone help me try fix the bios ? I tried myself but no change. Laptop start up and after one restart stil stuck with not screen.

Thanks for help. Otherwise same issue. Maybe I have problem with chip that control CPU because of liquid damage. No fysical damage, but VCORE is stuck on one voltage. No VCCGT voltage. No Image on HDMI.
On attachment image is visible previous liquid damage. No blowned components.

Program the both files together and in the first boot you must enter the bios menu to disable security options (Default).

EC message disappeared but do you know why SATA isn't recognized anymore?
