Greetings to the forum participants! My name is Lev and I am a retired electronics engineer. I devoted my activity to radio engineering, electronics. And even though I'm 73 years old, I'm interested. It so happened that I did not have to repair laptops during my working life. Now I have bought some faulty laptops and am studying and repairing. Also, my Samsung laptop has recently deteriorated and I am trying to repair it. I don't know English very well, so I use a translator. That's how to say my first message about myself.
