Re: HP ProBook 450 G3
450 G3, two long two shorts, BIOS corrupted. Got laptop as non-working.
Serial 5CD6104L89
Flashed BIOS from https://www.badcaps.net/forum/showpo...68&postcount=2 and it boots and works, but after BIOS update from Windows to new version, charger is not working. Flashed back via programmer, working.
Also, I thing there should be dGPU, but not showing.
Please suggest other BIOS
Many thanksComment

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).

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... -
This laptop is the same laptop I was working on in this thread and I wasn't sure if I should post a new topic or post in that thread because I already solved the issue that thread was discussing and this is a completely different issue although it is dealing with the same laptop. I decided to make a new thread since it's a new issue, but please move if I made a mistake.
