Hi i need to program chip winbond 25Q16DYSIG11524 - From my understanding it is 2MB/16bit chip - i did screw up because i did a backup with programmer but with incorrect settings (1MB and 16MB read and save as file) i will attach photo of the chips. Any idea if i can found new bios (BIN file) to program?
I only touched the one with green dot on the picture - now laptop is flashing led indicator orange and white + it dont post or show any picture on the screen - and after turning on couple of times it only spins up fan at 100%.
Motherboard have a number: 6050A2637901-MB-A02
My bios backups (idk if correct - probably not) in attachment
EDIT: Sorry for posting in separate topic - i thought that original topic from 2019 was too old and i would meet with scrutiny because of digging up older topics. Thank You for merging.Last edited by serge17; 02-29-2024, 09:15 AM.Comment

I think you did a BIOS update, and maybe twice.
Or maybe someone tried to program your Embedded controller without BIOS from the same board.
Better go to a good known repair shop so they can reprogram your EC and BIOS for you.
It should work for you and also it can fail. Good luckComment

Hello everyone,
a few years ago, I flashed the BIOS of my HP 850 G1 with a generic BIOS bin file which did not include the Serial Number. After that I noticed that the backup file that I took from the original BIOS was corrupt and I coudnt revert back to the original BIOS. Now, everytime I boot the machine I get following error message: "The machine is not in commited state". I tried a few tools, but nothing worked. Could someone here provide me with a functioning BIOS bin file?
Here is my Laptop Data, I hope this is everything what is needed:
PCID: A3009DD10303
Serial: CNU412BKRP
Product: H5G44ET#ABD
Model: HSTNN-I11C-5
HP Elitebook 850
CT: PDXVU001X6G2R5
MAC: A02BB830D41E
If anything is missing, please tell me, I will answer as fast as I can.
Thank you all in advance! I hope you all have a nice day.
Best regards

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.

Hello everyone,
I am requesting urgent assistance to unbrick my laptop, a rebranded TongFang GK7MRFR chassis. The laptop is completely dead following a faulty in-OS EC flash attempt.
I have successfully used a CH341A programmer and can read/write/verify both flash chips, but using my backups/extractions has failed to restore power. The root cause is likely a corrupted Intel Management Engine (ME) region or an incompatible EC/BIOS pairing. System & Hardware Details- Barebone / Chassis: TongFang GK7MRFR
