Hi, I have HP Probook 450 G7 with no display.
All voltages present, so I think the problem is bios.

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?

Hello,

Looks like this is one of rare places where I can ask for help about bios for HP, help will mean a lot here.
I got dax8mmb18d0 rev d
I will attach both bios here, I can't guarantee those are untouched because someone was doing something before me on both chips. Laptop was locked but working, now laptop is at my place, not turning on, just light on caps lock, charging light is normal, no screen, no boot.
Before this state guy told me that laptop was working for few days. If someone know what a problem can be, check both bios files I have read and please if someone can fix them, will be nice. I hope someone didnt make mess with bios files.

Thank you in advance a lot!
