Hello board and all the friendly and polite people out there, who are willing to help a person who has come to a dead end.
My problem: a bios password that needs to be removed.
I've read the rules of this board.
# rule 1 "read the guides post".
I've done that.
# rule 2 "try the methods of the post"
I've tried the available options. (RCUnlocker and HPUnlocker)
# rule 3 "explain what happened"
Only HPUnlocker produces a correct file, the other one does not create anything (says wrong binary). But HPUnlocker created an bios _unlocked.bin.
reading and writing the file back to main bios (I didn't try EC bios), worked (verified by NeoProgrammer). After flashing I disconnect BIOS battery, waited 30 seconds, booted, but still password is requested
# rule 4 "Use search function in case someone already answered your request"
I tried but couldn't find a detailed turoial or something else. But this thread has many answers, but nothing is clear to me or is helping.
# rule 5 "Post under a related thread if it exists"
I use this thread here.
# rule 6 "post identifiers"
Laptop: HP EliteBook 840 G5
ProdID 5FT31EC#ABD
SN: 5CG8354TKB
I've attached the BIOS file.
Please let me know what I should actually do. I mean my BIOS file is already unlocked (hopefully), the chip has been written correctly (says the verification). Maybe I need to read/modify the EC chip aswell? Or do I need to press any specific keys? Please help me. By the way: I am usin CH341A programmer and CLIP adapter. I have no soldering station.

Thank you for the effort SMDFlea I can't seem to find a picture of around the bios chip to see if parts are missing. My solder job looks just fine.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
- External display (HDMI) shows

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.
