Alright, heres the deal. The fan on my laptop hates me. I.E. today when I logged on, I was checking my e-mail like normal when I got this nifty little pop up that said "Windows has detected a cooling problem on your computer. Please shut down and return for service." Or something along those lines. Except I know that it had to do with my fan because my fan hadnt started at all.
Now my fan has issues anyways. So I finally got it to start by just. . . blowing into the passage a bit to get it started again, which it worked.
I guess what I need to know is if I just need to replace the fan (if I even can on laptops).
So, any help would be much appreciated.

Getting inside a laptop is a difficult job unless you know what you are doing!!!!

IF YOU DO NOT KNOW WHAT YOU'RE DOING, DON'T DO IT! Sorry to be a little extreme, but the computer (especially laptops) are very sensitive, and one little static shock, and you're computer is completely ruined.

I didnt mean myself lol, I just meant if I needed to take it in someplace to get it replaced =p

Oh, well I would look on your computer manufacturors website for compatible components (or you could call them as well, but I tend to think it's not worth it). Your tech should know (I hope).

EDIT:
If it is not one of your fans failing, there are also products on the market that sit under a laptop and cool it as well.

Is it an old laptop? It might just be full of dust. Maybe a can of compressed air could help.
