I found a laptop while cleaning up in the basement. I had that in operation until one day he just stopped. Since then I can't use it anymore, which is a pity and since then it's in the box. Charging cable is available. If I turn it on, the screen is black. Can I fix it myself, who knows what advice?
Maybe the hard drive is over. Take the computer to a repair service and let them advise you
Well, most LT have a monitor port. Maybe connect it to a monitor.
Monitor stays black and you say hard drive? Because? ♂️
Then there's the NEN error that the hard drive is empty or not connected
