When I got my laptop earlier this year, I wasn't aware that using it on a pillow was a bad thing. Many months later, I've realized my mistake. However, even placed on a flat surface, my laptop is running hotter than it should. How do I properly dust the fan of a XPS 15 L502x laptop WITHOUT opening it up and voiding my warranty? I'm using Windows 7.

How do you know it is running hotter than usual?

I guess I really don't. Where can I find out what normal temperatures for my laptop are?

The typical laptop should run approximately 35-50C at the extreme high end. There are free utilities that you can download to read temps, but they can be off by several degrees. You can get a CPU temp reading from your BIOS, but by the time you reboot and enter the BIOS the CPU could have cooled by several degrees. I have always built my own desktop computers and use a direct sensor readout to an LED for my temps so I never use the software variety. Maybe others can suggest dependable utilities.

You can use HWMonitor to check the temperatures.

Yikes! Then according to HWMonitor, I'm definitely having some overheating issues. We're talking over 50°C and into the 60's or higher.

Your CPU has a maximum temperature of 100C. The temps your reporting isn't to bad but i suppose it could be better.

Would clearing any dust from my fan help? The only problem is actually seeing the fans through the grates on the back of my laptop. I don't want to blindly shove a toothpick in without knowing for sure.

Never do that. Those grates Plastic cover a metal heatsink.

First step try this HP laptop cleaning method and see if it helps. It really applies to all laptops. It has steps using a can of air. Do it with the laptop off.

It isn't dust on the fan, it is dust that block the airflow through the heatsink. There are pictures in the HP article showing what a clogged heat sink looks like.

Do not try and open the laptop.

Good Luck
Roger

You are going to have to try Rotor's suggestion as taking a laptop apart can be complex at times.

When cleaning a laptop, should the battery be low on power or does that make any difference?

Here it is

Don't Forget shutdown while cleaning it.

Good suggestions above. The battery level makes no difference in cleaning the dust out. Just FYI...accessing the hard drive and memory modules is simple, just a removal cover on the back of the lap. See your manual that came with the computer. It might provide more access to inserting a straw from an air can to blow out the dust. Also... make sure the cooling fan is actually spinning, if you hear it spin up on boot that should let you know. Short of dis-assembling the lap, blasting a short burst of air from a can is all you can do to blow out dust from the CPU heatsink on a laptop. Desktops are a lot easier to work on, but that is another subject.

Do I have to worry about damaging my fan engine by blowing air into the vent?
