The usual routine upon getting home in the afternoon: drop off my Bag O’ Stuff in the kitchen, enter the office just long enough to start up the computer, and make wardrobe adjustments suitable to the day. By the time I get back to my desk, the Windows startup should be complete.
Except for when it isn’t. The other day, I got some insipid beepage and the threatening warning: “CPU Fan Error.” So far as I can tell, this means the UEFI (which is Urdu for “BIOS,” or something) didn’t see it spinning.
Fortunately for me, the next day brought a box from Amazon, including a hell of a lot of canned air. I must have gone through a third of a can relocating dust particles from Point A to several dozen Points B. The problem has not yet recurred.
