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

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.

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...
