Namely: I found three laptops, but without a battery or power adapter. That means I don't know if they still work. Can someone help me, or rather, does anyone know how I can tell if the laptops are still running?
By buying a power supply…
@xxxcyberxxx Yes, I know that too. But maybe a way without spending money on it or having to buy anything?
Spend without money? Borrow a universal charger from friends / family if they have one…
Otherwise you won't get around it
OK, thanks for your quick reply
Why found it, maybe they shouldn't go away anyway, and someone has already removed and hijacked all valuable parts such as storage, etc? If you look at the housing, you can see what voltage and amperage are required for the mains connection, and if you look on Ebay, with a little luck you can find the right power supply for a few euro, but before you invest the money, you should already be clear whether the box itself has any value. Often there's a nameplate on the bottom, based on the manufacturer number you can google what such a device could be worth, otherwise you can dispose of it as electronic waste free of charge at the company responsible for the city or district and have more space in the attic or cellar won.
