The dust bunnies help trap the heat....scooshing is a nice way to help your PC.... At least that is what they told us in Scooshing school ! DD
I opened up my computer and while I was scooshing I noticed there was a little flat battery next to the motherboard. Whats it for?
I'm in the IT department for the company I work for. We get in user's laptops daily and "scooshing" is a very effective method to use. It makes a significant difference.
