Hi,
I have a Fujitsu Lifebook E547 vPro that does not boot anymore after Windows Update tried to install a new Bios version. Screen stays black no post - only the numblock light blinks.
What I've tried:
I have used my CH341A to read the bios chip (25Q128FVSQ) (Dump attached) - I think the dump is "good" because I could find the Serial number in the data and also the Winkeyfinder found a windows key.
for the lack of any other Idea I took the bios from this post (https://www.badcaps.net/forum/troubl.../troubleshooti... -
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.... -
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.

🧩 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

Apologies if this is the wrong forum, but I'm not looking for a specific BIOS file, I'm trying to understand how one makes a clean BIOS file. So here's the background. I have 2 HP EliteDesk 800 g2 mini 35w pcs. One is working fine; the other doesn't have display out or working USB's nor does it have any flashing error lights. The CPU does get worm enough to cause the fan to spin up, so I think it's posting, but I just don't know. I had it working at one point but trouble started when I tried to put in a drive caddy that had a cooling fan on it. I thought it would be compatible but wasn't...
