Re: Bios For Hp Probook 440g2 and Elitebook 840
I'm absolutely sure it is bios. Cause some genius desolder bios chip with locked bios (before that laptop was working, but locked), threw away chip and then he came to me with laptop without bios chip.
I have few winbond 25q128fv and every single time with every singl bios file I find- I can't verify. Exept the one Murtaza527 gave me. But, even then, laptop can't power on.
That all story. I'm desperate now...Comment

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.... -
Greetings badcaps community,
I havent done this for a long time and want to start it all again, after some evil and annyoing illness.
So I apologize in advance, if some phrases might sound a bit like gibberish or illogical to you.
Im trying my best to fully describe what I plan to achieve and hope I was choosing the right sub-forum for my new adventure.
I have a Elitebook 820 G1 and a Elitebook 840 G2 here.
These ask for a password when entering the BIOS, but boot just fine from the internal SSD.
I learned that desoldering...10-29-2024, 06:03 AM -
Hello everyone,
I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
🧩 Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight

Hello everyone.
In the last 8 months I have manually flashed about 150 HP laptops (BS series, Probook, Elitebook and Zbook). There are about 50 HP laptops, as I have already written before, they have been automatically flashed through windows updates.
Approximately 15% did not start after flashing.
I got the HP Pro, Elite and Zbook to work again with the exception of one using the familiar key combinations or the well known bios flash stick methode.
An Elitebook 840 G6, like many HP notebooks from the BS series (exclusively those with dedicated graphics c...03-08-2024, 10:49 AM -
Hello,
I have an EliteBook 850 G5. After a Windows update, including a BIOS update, the notebook turns on, but the screen remains black, and the fans spin at high speed—nothing else happens.
I assume the BIOS update failed, so I searched for the BIOS chip.
I found a Winbond chip located between the RAM and the hard drive, which has a size of 32 MB.
However, the BIOS update available on HP's website is only 17 MB in size. I used the update version that was previously installed when the notebook was still working.
Can the corrupted...
