My laptop started restarting unexpectedly during online conferences. I had to urgently hand it over for repair, as the work was standing. The service did a free diagnostic and found a problem in the power supply inside the laptop. They had spare parts, so the repair took only a few hours. The cost pleasantly surprised me, I thought it would be more expensive. The device returned to me in a normal state, all without brakes and failures. Plus, I got a warranty document, so now I'm calm.
