Hi everyone, hope everyone's having a great day.
I have a Lenovo Thinkpad X1 Yoga Gen 3 for repair. (20LES3T900)
I looked in every corner and the laptop seems fine. Its pulling 500mA but no display, no noise, nothing.
So I assume its a BIOS issue. I downloaded the BIOS with CH341A and opened it on ME Analyser and didn't receive any errors.
Does this mean the BIOS is fine? making it a hardware issue?
I downloaded fresh BIIOS from the Lenovo site and used Hex Editor replace the Lenovo's BIOS into my BIOS region. But the file size ended up being... -
Hello everyone, I happen to have a Microsoft Surface Pro X 1876 in my hands. It was brought to me by a friends which happen to have taken off the bios chip to test another motherboard.

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, the bios on my Lenovo TD350 ThinkServer got corrupted during a bios update, the bios restore function killed the Server.
I need to flash the bios inside the MX25L12835F SOP8, i have already desolder the chip and solder it into my SOP8 adapter and read it with a ROM programmer.
I use the innoextract 1.9 software to extract the bios file from the .exe file that i download from lenovo website, can you help me edit the Hex file (removing the Index part and resize the file)?
This guy claim to have done it https://forums.lenovo.com/t5/ThinkSe...doesnt-Start-u...
