Re: Any practical examples of success repairs

Hello from France,
mon2 kindly advised me to post a thread to ask the question(s) I'm concerned about. I'm new to the forum and I'm looking for practical courses for troubleshooting pc motherboards especially laptops in Europe, if possible in France.

Please help!! 🎶I'm just a girl in a world that wants to scam me out of lots of money for any tech stuff/repairs 🎵 Seriously tho, I'm poor&I can't afford to get laptop diagnosis, especially if it ends up needing a new motherboard.
Where I live, all the tech shops are run by very...

My issue isn't massive, but I'd like to get this solved since I'm trying to fix a friend's laptop.
A botched BIOS update by Lenovo bricked this laptop, so I used my BIOS programmer to reflash the BIOS on it and saved it from an early demise. All is good now, but the BIOS reports the S/N, MTM and UUID...
