Do others who work on technology get things left behind?

I often get left with equipment that people don't want to fix. They say they will pick it up but then never answer your calls and such. I now have people sign a form stating that they will make arrangements to pick up equipment within 14 days.

Most of the stuff left behind is just crap. We are talking about computers purchased at Wal-Mart or Black Friday sales with a CPU that barely has enough power to boot it up. It doesn't take much damage to total out these units.

Sometimes I am left with better stuff such as Core i5 laptops and the like. I had a couple Sandy Bridge era i5s left as well as an Ivy Bridge i5. The most recent one was a Haswell based Core i3 HP Pavilion 13 x360 convertible laptop/tablet that someone had left out in the rain for two days. The hard drive, motherboard, and RAM were toast but the screen, keyboard, and the rest were fine. I have plenty of spare drives and RAM so that wasn't an issue but the motherboard was specific to this unit of course. A little research showed me that they made these in a couple different AMD flavors as well as a Core i5 version. Since these are low power units, they are integral to the board. I purchased a Core i5 board and installed that as a replacement. The Core i5 was the highest performance option for this unit. Now I have a nice little travel laptop.

Another low power Core i7 ultrabook was left. The hard drive was trash and since it required one proprietary to the unit, it wasn't going to be the cheapest thing to fix. I had one of those caddies for putting a hard drive in the optical drive bay so installed that when the owner didn't return phone calls after 14 days. It is a low power unit and a 1st generation so it isn't that powerful compared to other i7 units of today.

Anyone else have stories of things being left? Anything interesting?
