How to grease fans bearing?
I would clean my PowerBook G4 Aluminium 17'' fans cause those are really loudy, the noise sounds like something vibrating, rumbling.
So I've follow iFixit tutorial to access the fans but the top of the fan is covered by a little metal plug that avoid me to grease the axe of the fan, I don't know how to remove or open it.
Does someone have a solution to clean and grease those PowerBook fans?
Thx by advance
