the bios is corrupt..remove the bios chip from the motherboard before reading or writing ..if you use the clip you may get errors..what programmer do you have?

Thanks for the good advice.

This is my working environment.
os: windows10
programmer: CH341A Mini Programmer
application: AsProgrammer

I referred to here.
https://github.com/boseji/CH341-Store
https://www.onetransistor.eu/2017/08...schematic.html
https://www.onetransistor.eu/2018/11...n-windows.html

Certainly I used clips.
However, there was no error from AsProgrammer, and it seemed that the BIOS was successfully dumped.

Now try removing the MX25L12873F chip from the motherboard.
Is there a way to check with me if the data I dumped is corrupted?

I noticed a difference in compressed size.
After sucking out several times, I tried compressing each.

There was one thing that seemed to succeed.
please make sure.

Re: HP Elitebook 820 G2 bios needed

Greeting,
I have a problem with the above mentioned laptop and I hope you can help me. The laptop was working quite normally and then suddenly it started showing symptoms where the white and orange lights change and during that time I can't turn on the laptop. Only after some time when it turns off those lights, I can turn on the laptop but it throws out the following error: "BIOS Identity Data Recovered, The Embedded Controller MUD data is not valid while MPM is locked. Please unlock MPM, and lock again to capture valid MUD data.". Sometimes it also shows the following error: Embedded Controller Recovery, The Embedded Controller Policy Settings have been recovered to their default state. The Embedded Controller Flash was recovered from Shared SPI Flash. I note that I did not touch anything about the bios.
Does anyone have any idea how I could fix this problem? Thanks!
