The other day, I was sitting with a friend who had her laptop on. I noticed that the fan was going non-stop and it was making quite a bit of noise.
Knowing that desktops and laptops both suck up dust and dirt, I knew that that was most likely causing the problem, making it to run loud and hot. I also knew that if it continued that way, it was only a matter of time before the machine would start overheating and locking up.
Fortunately, this is very easy to fix. What is needed is a small screwdriver and a can of compressed air, which you can pick up at Radio Shack or electronics store.
What I did was to turn off the laptop, unplug the power cord, turn it over, and remove the battery. On some laptops, there may be an access panel on the bottom close to an air vent on the side or back of the laptop. Unscrew the panel and remove it. You should see the fan right underneath.
Now it’s time to blow out the dust. Hit the fan in short bursts from lots of different angles, making sure to blow most frequently in the direction of the air vent. If there isn’t a panel, spray through the air vents.
After blowing a fairly substantial amount of dust out of the laptop, I replaced the panel and battery and powered up the system. If your laptop is more than a year or two old, it’s probably overdue for a similar cleaning.
