Re: thinkcentre m82 bios
clear the CMOS using the jumper.Put it on 1+2 start up and leave it for a minute,then press the start button for 10 seconds to shut down.Put the jumper back on 2+3 and start up. You can find where the clear CMOS jumper is in the hardware maintenance manual, page 76

How did you create these clean dumps? I tested both of your dumps and they work perfectly! Just curious how I can create or clean BIOS dumps.Comment

Re: thinkcentre m82 bios
Am I correct to assume that I can just load the EC file into a hex editor and replace the MAC address which are located at file offset 0x1000 and 0x2000 with the MAC address from my board?
The same goes with replacing the serial number, product number and product name in the BIOS file?
I brought mine back to life with a BIOS + EC that I got from Lab-One Inside forum when I searched for IS7XM V1.00 BIOS but because of the MAC address is different, onboard ethernet doesn't work. Detected by Device Manager but can't load driver. If I had edited the MAC address, it'd probably work.Last edited by прямо; 11-21-2023, 01:59 PM.Comment

The only way i know that works is to follow this steps. First make from another computer a laptop a bootable usb or cd with the BIOS update and remove the power corde from the computer with the problem.Step 2 open the PC and remove the CMOS battery.Third put the jumper on CMOS reset pin 1 and two.Insert bootable USB and leave it to flash the BIOS and when it reaches 100 % will shut down. Step 4 remove power cord, insert CMOS battery and move the reset pin jumper back to position 2 and 3.Now just restart and all will work.Comment

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 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

I need a BIOS dump for ThinkCentre M910 Tiny.
The BIOS chip is : Winbond 25Q128JV
Board : IQ2X0IH ver 1.0
I was using a chip clip with my xgecu pro which led to a corrupt BIOS dump, and the BIOS chip was since re-flashed with the donor BIOS from this thread:

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...
