I found a fairly new but damaged HP 2-in-1 in the dumpster. The screen was smashed, the case bent and the prospects of repair dim. 2-in-1s are really tablets which plug into a base with keyboard. Hoping for salvage, I pried open the base, removed dozens of screws and finally realized the good stuff was in the tablet part. No screws so I started in one corner and pried the screen and motherboard from its case. More screws and I found memory and CPU were soldered onto the motherboard. The hard disk is an M.2 2280 SSD which I did extract along with the Wifi card. There were flat batteries (lithium ion) in both the tablet and the base which I suspect are hazardous waste. There is a waste collection area near my gym so I will drop them off.
I used to repair laptops but thin ones are probably not worth the trouble. Lots of Mini-PCs that can be plugged into a TV set and smart phones what can be plugged into a Superbook. Maybe the dinosaurs are going to become extinct.
