Okay, maybe Bill Gates since I have a PC.
But today I heard a rattling sound in my laptop's fan and then all of a sudden my fan stopped working. Not good when you have a laptop.
When I was in university, I had to get my laptop's fan replaced after 4 years and it cost about $150. So I was not looking forward to paying that again after only having this laptop for a year and a half.
Instead I decided to take out my toolkit I got for Christmas while in university (you would be surprised how many times I've used that thing!). I took out the battery and unscrewed some pieces in the back. Nope can't get to the fan that way. So I pulled off the keyboard and was able to get to the fan. Then I saw it....a screw was jamming the fan from moving. I wiggled it around and eventually tipped my computer upside down and it with the screwdriver was able to wedge it loose. It came out and I put everything back together and it works like a charm again.
Well not exactly perfect....this is Windows Vista we are talking about ;)
