I’ve been doing a lot more electronics repair recently.

Second monitor wouldn’t power on/intermittently. Went on eBay and found someone selling the main board from a unit with a broken screen. $30 which saved me from buying a $170 new one.

Soldered a new switch onto a $50 mouse for like $5

Ordered a nice keyboard with hotswappable switches, had 4 broken solder joints once I put all the switches in. Not sure if that was me or bad QC but I didn’t want to wait 6+ weeks for round trip return to China so I opened it and was able to resolder all of them and it works perfectly.

have ARM CPUs which means they aren’t PCs

Why on earth would architecture have anything to do with it?

only support UEFI booting so aren’t PC compatible.

Oh wow, I don’t think anyone using the term “PC” this century was referring to “IBM PC-Compatible” like it’s 1981. The only vestages of that is that the term excludes Mac even today.

They can’t canonically exist midair
