Re: Hp Probook 6545B bios dump wanted
Hi - I have a Probook 6545b BIOS problem too. I tried to update it to the latest BIOS on HP's site.
The update failed - the current bios is half working - boots operating system and grub but no keyboard input. The keyboard works fine in the bios set up screens and boot device selection - once boot device is selected and bootstrapped kbd no longer works.
The problem is that the keyboard won't work once GRUB (Linux/Win10 dual boot) is started.
I can access the BIOS setup screens - keyboard works fine...
GRUB starts linux by default. the kernel reports: "Unable to enable ACPI" and " i8042 Can't reactivate KBD port"
I have tried the "Windows Key + B" update from USB suggested by HP (Won't work)
I have tried HPs "bootable" USB solution (would not boot)
I used Rufus to make a bootable USB stick - copied HP " bootable" erompaq. exe, config.sys, and rom bin file.
erompaq loaded but needs an F10 keypress to continue (KBD not working once freedos loads from USB stick)
Tried filling KBD buffer with F10 keystrokes from BIOS setup boot selection screen before and during selection of usb stick as boot device.
this started the rom update but then complained the machine needed to be on mains power (it was) - my guess is it is checking via ACPI if plugged in - corrupt bios has broken ACPI)
Does anyone know of a bios rom flash software that can just update bios without checking acpi or needing user interaction (kbd not working under corrupt bios) that I can put on a usb that self boots and updates 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... -
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.
