Hello,
I also have a HP 840 G5 which powers on, Caps Lock blinks 5 times, then fan goes into fast mode
Everything looks OK, all voltages are there except VCore (the regulator responsible for VCore doesn't get configured via SVID).

Thanks!

Thanks! I actually learned to rebuild the BIOS image by myself in the meantime. There was a problem with ME region. Bad checksum and structure was even detected by MEAnalyzer.
The notebook works fine with my rebuilt image. Thanks anyway!
On first start it actually behaved the same (caps lock flashes, fast fan) but after that the fan stopped and the system started to boot. So if anyone is facing the same issue and trying the repaired bios, be patient on first start after flashing new image.Comment

Hi,
I'm having the same problems as many others where the laptop fails to boot. Is it possible to clean the bios?
Also, ME Analyzer reports Error: Detected CSE Extension 0x03 with wrong Partition Hash at FTPR > FTPR.man! on this file.
Thanks .S/N:5CG9256VP8Comment

Hi,
I did the same process (replacing the ME region with clean one) as I did in my case. However, I could not find the exact same version of the ME that you have in your BIOS image. So I used the same version that worked for mine.
Your version: 11.8.94.4494
I used: 11.8.95.4551
So don't be mad if the laptop self-destructs after booting with my rebuilt image
The ME Analyzer error is fixed with my rebuilt image. My error was exactly the same...

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.

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.

Hi, my laptop wont boot at all
With original bios no POST, only LED lights
With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
Some issues
A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
B- If updated from 500LN version 203 to 300, the battery stops being recognized
Things I tried
1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble... -
Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.
Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...
