My final solution to repair bios and restore original motherboard specific data:

1. program bios chip with dump from post 249 -> bios does not contans machine specific data
2. after powering on the motherboard it gives some error messages like in post 250 about the missing data, however it is possible to launch Windows
3. when Windows is up, apply BIOS Configuration Utility from post 254 in the following way:
3.1 start CMD as admin and,
3.2 use BiosConfigUtility.exe /get:"actual.txt" command to write all available tokens / variable into actual.txt file
3.3 use BiosConfigUtility.exe /setvalue:"token from actual.txt","new value" command -> e.g. BiosConfigUtility.exe /setvalue:"SKU Number","G3K60EZ#AKC" will program G3K60EZ#AKC as SKU
3.4 repeat step 3.3 until you set all required tokens.
In my case theese were: Product Name, SKU Number, (ENTER) Feature Byte, (ENTER) Build ID, Serial Number, Product Family, System Board CT
3.5 when finished use BiosConfigUtility.exe /setvalue:"Manufacturing Programming Mode","Lock" to lock your bios
4. shut down Windows
5. power up your machine and it should start without any warning


Thanks everyone for your help!

please try this and report

Thanks! Finally I did not test it, since this dump does not cointains my motherboard specific data.

Another interesting thing: it shows Probook 650 G1 instead of 640 G1.

Hi,

Thanks for your help.

Now the machine powers up without error message, but every motherboard specific information are incorrect. Serial, SKU, system info, etc... How can I restore my original data?

Thanks for your help!

Well it is much better then before, but there are still some missing information. Product family and System Board CT number are missing if I understand well.

Entered into BIOS and find the following informations.

How can I update the missing informations as well?

If your original does the same then more then likely u had a bad read or the og bios was already bad. do you get any power atall like fans spinning ect ?

You just need to restore DMI. I don't have DMI for this device so I borrowed from other devices, only the serial number and product are yours.

With this new dump there is no picture after powering up. Problem is the same as with the original bios dump.

Any idea?

Thanks for your help!
