Here is my approach to laptops. Check eBay completed listings for the models you have. Include the words “parts” or “repair” with the model number. If similar units are selling at a price you deem worthwhile, place in keep pile. If price is too low, remove any more than scrap items for a forum buyer and add the rest to the scrap pile (I don’t disassemble laptops).

You need to acquire a few laptop power supplies. I can do a lot with 6 or so. Try powering on the laptops and make notes on post its so all laptops are documented. Make/model, cpu/speed, ram, power/or not, screen condition, other damages or missing peices. Units that power on, try to get to the bios page (one button during start up) it will give you the specs and the buyers like this picture. Even laptops that don’t power on can have value, people need covers, body peices, whatever. I remove hard drives but include the caddies.

I use flat rate boxes, but that’s because shipping is high for me. You may have to ask at the post office, the large flat rate game board box works well. If you get multiple of the same or similar laptops, pair them in one box to reduce shipping per item. Items sold as for parts or repair can not be returned. Just document well to avoid feedback issues.

Now you are selling laptops with basic specs/functionality and making way more than scrap without extensive refurbishing. You make more money, but the buyer can still make money too.
