Hi There,

Can you please rebuild a bios based on this file ?

I have a laptop that came in that no longer display after a bios update, the customer made a backup of the bios before proceeding, the backup file is attached.

I have tried the files from https://vinafix.com/threads/hp-probook-640-g2-circus-6050a2723701-mb-a02.23720/post-42236 and there is no display, just high fan speed

The bios chip on the laptop is not readable hence i provided the backup file that was done by the HP Bios update application, i have already put in a new chip that we can read and reprogram but we need a bios that can work.

Model number is HP ProBook 640g2,
Serial number is 5CG7402YQ9,
Product : L8U35AV

so you need to use another BIOS, can't rebuilds and rebuilds not all it's not always good
above many BIOS unpass good why not use ?

I have already tried about 15 different bin files based on this thread including the ones from post #1, all without success.
The file i posted above was created by the hp bios update application hence i thought it could be used to build a new image.

that shows the problem is not from the BIOS,
You only know how to program BIOS and don't know how to repair other components?
