Thanks for your answer dear peste. Unfortunately, I can't access the BIOS because it's password-coded. No idea how to secure it. Best regardsComment

Okay, I understood. The version is: P78 Ver.01.40 11/19/2021 - Best regards

Hello to all the experts. Can anyone help me? So far I have only found out that the "BIOS chip" has to be soldered out and programmed externally. Is there really no other solution? Thanks for every message and best regardsComment

Yes, if you don't use the CH341A (which works poorly with clamps)

Hi Guys,
Would you please help me to clear the BIOS for HP EliteBook 840 G4
During the Windows setup process, it prompts you to enter the company credentials.
Thank you in advance.Attached FilesComment

We can`t help you unless you post your bios backups, and type and post the laptop serial number. Read https://www.badcaps.net/forum/troubl...before-posting

Thank you SMDFlea for the reply,
How many Bios backups do I need to post to fix that issue?
Main or second BIOS too?
Thanks.Comment

Hi all,
My Samsung Galaxy Book 2 Pro 15.6-inch laptop has no display and won't boot.
The charging red LED lights up, but the charging screen doesn't show any indication.
When I press the power button, the blue LED cycles on and off three times, then the screen doesn't turn on, and the device won't boot.
(I've tried removing the battery and resetting the device, but the issue persists.)

Hi guys,
If someone would be able to provide some expertise, I'd be very grateful.
BIOS Corruption - Cause
So I managed to corrupt my machine by installing linux and enrolling custom secure boot keys. I did choose to enroll the Microsoft keys as well, to prevent any potential bricking due to 3rd party drivers from HP being signed with those keys.
After doing that, and rebooting(it did boot, powerLED, fanspin etc.), the laptop did not give any video output on the LCD or video connectors. I think I was able to get in BIOS and trigger the beeper by pressing ESC.... -

Hi, my laptop wont boot at all
With original bios no POST, only LED lights
With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
Some issues
A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
B- If updated from 500LN version 203 to 300, the battery stops being recognized
Things I tried
1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble... -
Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.
Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...
