HP 640 G2 Bios Request
Hi Guys,
I have a machine a customer brought in, HP 640 G2 with a corrupt bios.
Mobo model number is circus-6050a2723701-mb-a02
The machine was working fine and they did a bios update, screen went black and nothing else after that.
caps lock blinks 5 times and fan runs at high speed.
They did make a backup of the bios before starting the upgrade, but no auto recovery method seems to work.
In the folder of the recovery bios, there is 3 files.
The 0151 zip file contains 2 bios files N76 and N87, with date modified 2020/10/23
The N76_0147 zip file contains N76 bios file, modified date on this one is the date of the failed bios update.
The files are 9 216kb, the bios should be 16mb.
I have already tried a few bios files without any luck.
Can anyone please rebuild the bios ?Comment

The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.
Suspected Cause:
I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.

Hi, I have an MSI PRO B660M-G DDR4 board with damaged BIOS and i need a bios dump from a real board, along with MAC, UUID and Serial Number info (eg. a BIOS screenshot and pictures from the board stickers).
I need to reconstruct the bios on my board, based on another bios image form a real board - meaning a bios image containing MAC address, UUID and Serial number. A stock BIOS is not suffiecient, as it is impossible to discover where the MAC, UUID and SerialNumber are stored. Tried with a similar board, but there are too much differences, and the stock BIOS is missing a lot of...11-17-2023, 10:56 AM -

Hello.
I tried to add a custom secure boot key (for secure booting Linux) to my bios, but after this, my laptop bricked. After adding secure boot key (via PowerShell) and enabling secure boot my laptop turns on, shows HP logo, and after 5 seconds it turns off and on, and it repeats forever.
My goal is to either turn off secure boot or remove my custom key from BIOS dump.
I'll attach my bios dump (version R79_011700) from my bios chip 25b127dsig, my keys (PK/KEK/db), and bios dump from another HP ProBook 445R G6(I found it on this forum. URL: https://www.ba... -
