Re. Interfering mice
Or my favourite, a system that one day just stopped working.
Found evidence of mouse infestation, including possible urine traces on MB and cables after we went "Full CSI" on the machine. Got replaced and mice dealt with sternly.
Ended up using hacked traps with a hair trigger, that would set them off if we used an air duster on them from 5 feet away.
Guess what, leaving laptop in bag outside, in the rain on a motorbike = bad keyboard in short order.
You can guesstimate the amount of pollution in atmosphere by timing how long a new keyboard lasts before bad keys show up, in some areas this is a six month MTBF.
