HP 15-da0117nl Lost BIOS info and no TPM

[DarthMick]

Hi guys,

i own an HP laptop that suddenly lost all info in the BIOS (serial number, model number, UUID and so on) and the TPM module that used to work is no longer recognized.
I have Windows 11 installed, but it keeps trying to reinstall the system files without success because the TPM is not present.

Now i need anyone here to tell me which tools i need to try to reprogram the BIOS and reactivate the TPM module.

The laptop data are:

S/N: CND838BGBD
4TW61EA#ABZ
Model 15-da0117nl
RMN:TPN-C135


Many thanks!!!

Should be posted in "Bios Forum" and not here.

Thread moved to bios requests forum. Post your bios backup in a zip/rar attachment.

I can make a backup of the actual BIOS, i don't have one made before things went wrong...Will that suffice?!?

It will have to do, yes go ahead and post it.

OK, here it is:

Your bios is new so there is no information, please try to fill in more information.

Thanks for your reply but...What kind of additional info do you need?!? And what i'm supposed to do with the attached 1.rar file?!?
I apologize, but i'm kinda new to BIOS programming.

Hi everyone,

i own a HP 15-da0117nl with lost info (serial number, etc) and other functions like TPM.
I have created an HP Recovery Key from another identical laptop, but i can't rewrite the BIOS entirely...In detail:
If i leave the SSD with the operating system connected, the Win-B process will start and finish, but the BIOS will remain the same.
If i remove the SSD and try the Win-B procedure with just the USB Key connected, the computer says that it cannot find the recovery files from the USB key.

Is there another way to fully recover my BIOS?!?

Many Thanks!!!

Thread merged with your previous topic. Try to enter the serial number etc using HP Bios Config Utility https://ftp.ext.hp.com/pub/caps-soft...it/HP_BCU.html .If that doesn`t work you will need to buy an SPI programmer to flash a new bios.

Thanks for your reply...I have already tried with BCU, but basically it says the BIOS is not in MPM mode so no luck...It looks like my only chance is having someone to reprogram the BIOS chip with an SPI programmer, am i right?!?
