Re: HP EliteBook 820 G1 Bios

Yes, of course. But I want to know if, for unlocking a bios password, I must make dump(s) of only the eeprom or eeprom AND EC ? And about making the bios dump, must I desoldier it (never do it before) or can I use a clip + ch341A + flashrom or ch341a software or another programmer software (which one in this case) ?
Thanks for your reply and best regards

you only need to remove the contents from the bios chip, it is good to remove the chip from the motherboard, and solder it on the programmer if you have ch341A,
and you do not have an adapter for bios chips ..
you can soder wires between the programmer and the chip bios on the motherboard,
if you can't remove it..do not use the clip because you will have errors..
don't forget to make a bios copy before writing the bios chip..if you have CH341A use one of these two programs ..

you will need an SPI programmer.

Re: HP EliteBook 820 G1 Bios

Hi everyone,
Thank you first for all the informations and services offered on the site.
I have to unlock a HP 820 G1 (bios locked). It would seem, to make a correct bios dump, that it is necessary, on this model, either desolder the eeprom, or solder wires to it (and dump for only the eeprom, not eeprom + EC). Am I right ? I do not know these technics: would you have a solution that would only require a simple clip? Do you need to use any particular software and, if so, which one ?
Thanks for rour reply and best regards.

Re: Hp 820 g1

Maybe you destroy a small cap/resistor near bios pads , try to verify at another motherboard or search HD picture to confirm.

Re: Hp 820 g1

already desoldering and reprogramming same problem? Even with new chip same problem

Re: Hp 820 g1

Hi,
Nobody can help on this ?

remove the bios chip before reading from the motherboard and solder on the programmer if you do not have an adapter ..maybe the bios chip is defective ..

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 ?

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

Re: HP-Compaq - Elitebook 820 BIOS DUMP

thanks for the help but it didn't get good. the motherboard is dead likely

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