Hello,
This is a completely hardware related issue. I have had my Compaq Presario C500 laptop for a couple of years now, and I've noticed that it's getting pretty dusty. A computer store wanted to charge me $60 for just removing dust from the laptop, so I decided to do it myself. The problem is that for some reason I just can't open the casing of my laptop. I'm pretty computer literate, but I'm a bit unfamiliar with hardware. Here is a picture of the laptop that I will try to use to describe my problem.
I unplugged the laptop and removed the battery, of course. I then removed all the srews that I could see from the back casing [which you can't see from the picture]. While I could slightly open the sides of the casing, It wouldn't come off. After searching online, I read about a different laptop that had screws underneath a panel that is just above the keyboard and is below the screen hinges on the front side of the laptop. This seemed to be the case with my laptop as well, so I took off the panel [it's where you can see the power, wifi, and sound buttons] and I removed those screws as well.
The back casing opened up a bit more, since those screws were apparently attached to the back case, but still only slightly. I can't actually get to the fan. There seems to be at least something else at the bottom of the photograph, below the touchpad, where the laptop closes, and where the speakers are that is holding the casing together.
I've managed to only scratch a couple of things and not break anything so far, because I've put this back together and tried again several times, but I think I'm really stuck this time. I don't want to break anything. lol. Please help!
Thanks a lot,
Dave
