My Bride came home with a chewed-up cord that goes to a laptop power block. It seems that they have a mouse issue at her Salem office. So the cord didn't work anymore, short-circuited. She asked if I could fix it, and yeah, maybe. But I had a better idea.
I keep cables and cords that I'm not using in a couple of little baskets in the computer room, and I coil them up and stuff them into toilet-paper tubes, with the ends hanging out for easy identification. Power cords on the left, ethernet and cable cords on the right. Sure enough, there was a power cable that fit her charging block. Problem solved.
She'll have to hide it from the rodents, however. I can't solve everything.
