Don't post pictures unless asked.
The bios chip must be unsoldered from the board before writing or reading..
do not use the clip, you may have errors..if you do not have anything to unsolder it with,
solder wires between the programmer and the bios chip..

..here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow

Hello,

These files were read from a non working HP 450 G7 Notebook.

The device was shut down during firmware update.
When powering on, display stays black and fan is spinning up.

Board: x8m-6l da0x8mmb6d0 rev d

Is it possible to fix this?
Thank you very much!

Thank you very much!
I wrote this to the main chip.
Second chip stayed like before.

Unfortunately the problem stays the same, fan is spinning, display doesn't show anything.

Is it possible that the issue is in the second bios chip?
