Bios Recovery (500)

[simbataz]

I have a HP ProBook 650 and it will not boot up.

It says,

A system bios recovery has occurred

BIOS Recovery ( 500)

Then Bios recovery via local media

It goes though a secure bios recovery and then just reboots and keeps going through the same process over and over.

It will not recognize any function key or the windows and B key, just freezes the computer.

It will not boot to CD or USB.

Hi, I had the same issue with update BIOS on my HP ProBook 455 G1, after update BIOS I've got 500 error and laptop was just freeze. 

I've resolved this issue using USB flash with BIOS files. I've written an article how to resolve 500 error and freezing of BIOS update step by step here.

Please if somebody will get the same issue use it - http://denieler.blogspot.com.es/2016/11/hp-probook-455-g1-error-and-freezing.html

Also, I think using this trick you can update BIOS on Linux\Ubuntu laptops
