Well, it looks like we inadvertently skipped a day on Friday. The construction we’ve had going on for over a week now required us to move stuff around and the blog post became a casualty of time. But never fear, we will persevere. Stiff upper lip and carry on and all that. Today, we’re looking at the second part of the compressed air myth, and hopefully teaching you a little more science. Because, you know, Science!
And we’re back for another exciting installment of the column where we learn that things we thought we know are actually wrong. Today, we’ll tackle a…well, not so much a misconception as an incomplete thought, centering on removing the dust and gunk form inside your computer case. And I hope you’re reading this outside on your laptop in a park, because missing this gorgeous day would be a crime worse than my occasional butchering of the English language.
#2: “You should open your case up every couple of months and spray it out with canned air. You can pick the stuff up for dirt cheap at the .99c store!”
Personally, I love compressed air. I remember as a kid turning the can upside down and pushing the trigger in real slow and watching the rapidly condensing moisture fall and his as the expanding air caused a sharp and rapid drop in temperature. It’s actually another common misconception that the liquid that comes out is whatever chemicals have been stuffed into the can, but it’s actually just the microscopic water particles in the air condensing around the nozzle. The air coming out of the can expands so rapidly that (as we learned in high school chemistry) it causes the air to cool. The reason this isn’t noticeable unless you push the trigger in slowly is that with more force, the cold air moves too fast to cause a noticeable temperature drop since the cold is spread out over a larger area. The more you know! ⌂
With daylight savings time catching us by surprise, and the temperatures here in NYC hovering right around 50, it’s finally safe to say that spring has almost sprung. There go those lift-passes I hadn’t had time to use. Oh well. And with spring just about here, we will soon be inundated with the usual flood of “Spring Clean Your Computer!!” articles, in which overly-peppy reporters who can barely turn on
their Powerbooks talk to an “expert” (usually, the only BestBuy employee who couldn’t invent a plausible excuse fast enough) about things that they don’t quite understand themselves and then string the words together in a way that makes things easy to understand but is generally pretty much completely wrong. Don’t you worry, we’ll get to the spring cleaning fever ourselves, but first we thought it might be helpful if we took a minute to dust off the shelves of conventional wisdom and common knowledge, pulled out the clutter of outdated truisms and unsubstantiated rumor, and replaced them with the bright, shiny, polished trophy of truth and accurate information. So without further ado, here is a list of the top 10 computer maintenance misconceptions and downright falsehoods, presented as a daily series (that’s right, you have to wait a day between tips):
From late-night Cheeto-powered gaming to breakfast-sandwich-in-hand commuter computing, laptops attract a lot of dirt, dust, crumbs, and various other bits of their owners’ debris. Add to that the air circulation system inside your computer, usually powered by at least one fan, and it’s tendency to suck in dust faster than Hoovering the Sahara, and you have a recipe for a mess inside your laptop. Not surprisingly, computers don’t like this at all. From dust clogging the fan and causing your system to run hot (which burns out critical components VERY quickly) to sticky liquids causing shorts or acting as magnets for other dirt, a messy laptop can cause all sorts of very expensive problems. You would not believe how many customers bring us their computers only to discover that all of their problems could have been prevented with a good cleaning now and then.
Luckily for you, several of our brave computers have agreed to undergo surgery so you can see how it’s done.
