“Cheap” really doesn’t describe how far I’ll stoop to avoid shelling out money. So when my laptop fan started sounding like a small Allison aircraft engine about a year back, I was not spending the $110 to get a new fan assembly — even the $25 for a new fan wasn’t happening. Instead I decided to treat it like any other machine in the shop: When it squeaks, I start with giving it some oil.
I wouldn’t try this on a computer with anything close to a warranty left on it — however, my trusty old plug of a laptop has no such high-dollar roadblock. So two times a year I pull the fan assembly out and very carefully work a little 3-in-1 oil into the bearing and put it back in the computer.
The good news: It takes care of the squeaking. The bad news: Whatever room it’s in stinks like 3-in-1 for about a day. All things considered, I’ll go with the smell for a day rather than the squeak for months, but attempt at your own risk.
