Thanks again for your help, but it didn't work. There must be a short on the motherboard. I give up on this board.

Did you try different RAM ? .How can you say its dead without further testing

Re: HP-Compaq - Elitebook 820 BIOS DUMP

yes, i tried more RAM. I did all the tests, voltage is fine everywhere. I'm out of my mind. Processor BGA error? With a microscope motherboard I looked carefully, everything was fine. 2 RAM slots are also good. But it's not working

Hp 820 g1

Hi all,

I'm trying to recover my bios file with CH341A and Asprogrammer 1.4.1 on a 820 g1.
I connect the clip, i push "Read Id with ?" chip is detected i do it again chip also detected and direct after the yellow orange led lights up and the bios is no longer detected.

All battery are disconnected and it doesn't matter if I connect the charger or not it's the same thing.

Any help or idea on this ?
