After I was recently reinstalling antivirus, something went wrong there and at some point cursor stopped on the screen without moving. Neither touchpad nor mouse were working. I tried to restart the laptop few times.. but result was the same - keyboard worked, but touchpad and mouse not. Though I am not an expert in using only keyboard I just managed to open control panel -> devices (where i can see attention marks in front of pointing device (I guess its touchpad) and mouse. The problem is with only keyboard working i dont know how to point on them to restart drivers for them or anything like that. The problem might sound stupid, but I am really begging for help or any advice as I am currently abroad and cannot bring my laptop to any service.
