Please fix this thinkcentre m72z bios
-
My pc updated bios through Windows Update and I was greeted with BLACK SCREEN WITH CPU FAN MAX SPEED. I don't think there is even a screen signal, because it triggers my monitor for a couple seconds and then the monitor turns off. I tried the other outputs as well.- I tried clearing bios, resetting bios, removed the CMOS battery, removed m.2 ssd, wifi, and ram. Still black screen with CPU fan blasting.
- I tried using the Lenovo BIOS CD and BIOS USB, but neither worked. At least I couldn't get anything to work.
- I could only locate two chips that look like bios chips. Could someone verify this

Hello everyone,

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

Hi,
I got a Lenovo Thinkcentre M75n (MT-M 11G5 PF3XG5V3) with a semi-bricked bios.
Short recap: I want to add an external GPU via the M.2 slot (Oculink). It does work but has some problems with the onboard GPU of the Ryzen 3 3300U. So I used Smokeless_UMAF to disable it. Since then I don't get any video via the external GPU nor the iGPU and Can't access the BIOS, but the PC does boot to the OS.
I desoldered the flash IC MX25U12872F and dumped the flash.
I also downloaded the newest BIOS and have it as a .bin file (I loosely compared the contents...08-04-2025, 07:46 AM -
