Re: HP Elitebook 745 G3 BIOS help
Try this.I don't provide help for people using CH341A and a clip. -
Hi all,
I have a now dead HP Elitebook 745 G3.
It had two bad DC-IN Mosfets which I replaced. After that Laptop was starting again and I got post. Next day I wanted to continue and tried starting laptop without battery. All i got was white blinking light and no screen. I checked 19V ,5V and 3.3V power rail and all are present. So I tried starting laptop on battery and it booted right away but it didnt charge.
So I kinda have a feeling it might be a frozen BIOS.
Unfortunately so far I only have experience with Intel BIOS, cleaning ME region etc. This is AMD Bios and I have no clue where to start.
Could someone please look at my BIOS/EFI files and check or give me advise on how to fix my AMD BIOS?
Thanks in advance!
Christian
Edit: I already tried BIOS files from this post (Flashed both 8MB and 16MB chip) but all I get now is orange blinking light.

Never mind guys. I fixed it. After another inspection I found a knocked off resistor. It must have gotten loose while replacing the DC IN Mosfet and then fell off at some point.
Laptop is working again :-)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.

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
