Good day. My name is Valera. If you look at my avatar, this is what oil workers in Russia look like. I am an electronics engineer and I like to take things apart, so people bring me all sorts of electronics for repair.

Hi guys,
I've just decided to join your lovely forum. I found this place while looking for ideas to repair the motherboard of my MSI GS75 Stealth 9SF
I hope to have fun, learn more about computer electronics and sharpen my electronics skills.

Hello everyone. I'm in my 50s, been playing with electronics since I was a kid. A ham radio operator since 1993. I work as an engineer for a major tech company. My expertise there mostly revolves around Linux and cloud engineering. I'm pretty much self-taught in electronics, reading schematics, soldering, using a DMM, scope, etc. I'm always looking for new experiments and projects to build, usually related to ham radio.

[oldham50]

Hello and thanks for this forum. I am a retired radio/computer technician. I have been a licensed Ham for over 30 years and like to try and fix things when they go bad. Sometimes the sun and moon and the stars align and it works. Looking forward to joining in on discussions.

Greetings all!

I worked in electronics for 20 years beginning at the age of 17.
When I was 37, I completed a BS in Computer Science and started working in SCADA, Process Control and computer networking.
From there I moved to management. While that paid better, it wasn't nearly as much fun. I always preferred getting my hands on the technology.

Now, I am retired. So, I've been thinking I might want to get back to tinkering with technology. So, I was thinking I might try my hand at repairing some motherboards or GPUs.
But, I figured I should find some schematics. So, I did a search and what did I find? badcaps.net!

This looks like a great place to catch up with what's going on.

I have a grandson that's just now getting interested in PCs. I'm thinking we might have a lot of fun together trying to make bad stuff work.

So, here I am! Ready to begin the research!

[Help needed] Lenovo ST50 softbrick after BIOS update


Hi everyone,
I'm dado98, and I joined this forum looking for help with a BIOS recovery issue on a Lenovo ThinkSystem ST50 (Type 7Y49CTO1WW, SN/J3025GH4, BIOS chip: MX25L12873F), and hopefully to learn more about how to deal with situations like this in the future.

During a BIOS update, the system ended up soft-bricked. I used a CH341A programmer to dump the BIOS chip, but unfortunately (yes, rookie mistake) I didn't make a backup beforehand. The dump I got is a 16MB file, but it's clearly corrupted.

I downloaded the "ITE138A_ST50_12MB.ROM" file from Lenovo's official site hoping to flash it as a .bin, but my BIOS chip doesn't accept it—it's only 12MB, while the chip expects 16MB.
With the help of ChatGPT, I tried to create a 16MB image by merging the original corrupted dump and the official ROM, but that didn't work either. Now when I plug in the power, the fan spins at full speed, but there's no POST, no beep, nothing—completely dead.

I'm here not just for help on this issue, but also to learn how to properly handle BIOS recovery, chip programming, and other related topics. I know there are a lot of experienced and knowledgeable people on this forum, so any guidance, advice, or even criticism is very welcome.

Thanks in advance, and greetings to all!
