Hello, I'm raket and I am interested in learning electronic repair. I've been fascinated by electronics since I was young, and I enjoy learning new things. Although I don't have extensive knowledge yet, I'm eager to expand my skills. Recently, I started learning C# programming with the STM32 microcontroller. Today, I purchased a Microsoft Surface Pro 7 that I found on eBay, which has a blocked BIOS according to the description. I'm excited to take on the challenge of repairing it and seeing what I can do.
