I have tried that before, but I tried it again just now.   It acts like it wants to start up the UEFI PC Hardware Diagnostics, but always gets stuck on 80%.

- Don't plug <usb flash drive> on bootup

- Plugin <usb flash drive> when loading bios file from HP Diagnostic > Bios Update procedure

Try again ...

I got this issue fixed, it needed a new motherboard.

Covered by HP's warranty ?

[zeusakatkm]

No, the warranty expired in January.

You don't need a new motherboard.

Cheap solution:

A professional notebook (chip level) repair store around the corner can:

- <desolder> bios chip

- flash

- <solder in> bios chip (old or new chip, depends on bios chip condition)
