Stationery & Office Supplies > Office Supplies > Office Equipment Cleaners > Electronics Compressed Air DustersWritten I think it is smart and essential to be able to either take your own laptop apart and put it back together, or agree that you should pay someone else to take it apart, maintain it, and put it back together.dvd/cd laser lens cleanerEither way, the laptop needs to be cleaned out every once in a blue moon.window air conditioner coil cleaningIf you were using compressed air properly, you would have used it every 3 months or so to dislodge whatever dust you could, to prevent it from accumulating over time.  alive air purifier for sale in canada

Otherwise, the layer of dust and debris can get so thick, it needs to be PEELED off the heat sink after you've taken the laptop apart... since by that point compressed air won't break it up... it will just push it away and into the fan... and turning on the laptop will just push it back against the heat sink.You should go to Youtube, and search for videos about your specific model of laptop, and watch a few that cover disassembly.  If this is a Dell or HP, you might even be able to find a Service Manual online at their respective support sites.  Do your research first.Keep all the screws on the magnet if they are not in their respective holes.If necessary, document where each screw came from... since some manufacturers like to use different size screws for different positions.  If this is a Toshiba however, there should be a letter/number designation next to the hole telling you which screw goes there.  Dell will write screw sizes next to the holes that use small screws, leaving you to  use the longest screws in the unmarked holes.

Pay attention to Keyboard Removal.  Either there will be a plastic bevel or plate at the top of the keyboard that needs to be removed to reveal the screws at the top of the keyboard holding it in, or there are screws on the bottom of the laptop holding the keyboard in... or there are little tabs at the very top of the keyboard just under the lip of the edge of the laptop that needs to be pushed in while the keyboard is simultaneously pried out a little.  You'd move to the next tab while holding the keyboard from dropping back into the hole.  You "flip" the keyboard toward the touchpad, so you can disengage the keyboard cable.  By "flip" I mean tilt it towards you, away from the screen.Prying apart the two halves of the laptop can be tricky... I use my folding knife as a wedge with a twisting motion, to lift one half out and away from the inner half, where the tabs are.  There are usually 4 to 6 tabs inside each edge, so when I'm on a roll, I'd flick twist my wrist 4-6 times with my knife in the front edge of the laptop, round the corner of the laptop, and pry gently the section where the optical drive is, and by that point enough of the laptop is apart to pull gently with hands to get the rest. 

Always pull carefully, looking toward the center of the laptop.  If you feel resistance, you might have forgotten a screw.  No harm in that.  I've been taking apart laptops for more than a decade now, and I still always check for screws I might have missed.But seriously.... watch a few videos first.  Get an idea of what to expect.Written For certain values of "safe" - if you're careless or doing it wrong, you can still cause damage to your laptop.Find the maintenance and service guide for your laptop model on HP's site first.From my experience the two Compaq laptops I had (NC 4200 and NW 9440) required a fair bit of disassembly to access the radiators and cooling fans. You'll probably want to reapply the thermal paste on your CPU and GPU in addition to cleaning the fans (remember to clean the old paste with isopropyl alcohol first)Written Thanks for A2A.Do a search "HP Model Service Manual PDF", and download the manual. This will tell you the easiest way to remove the relevant sections and cooler so that they can be cleaned properly with compressed air.

This is one area that is designed to be relatively simple. You will not usually have to remove anything attached by thermal grease, only mechanical components.Your machine will last much longer and perform much better if it is not overheating.You may not find your particular model on Youtube, but there are plenty of videos that will give you basic idea of what you'll need to do.Be especially aware of dust that hides in places not visible from the outside. You may want to use a vacuum to remove thick build up before you attack the system with compressed air.Written Yes, it is safe. You should disconnect the fan or hold it in place. But what you also need to do is put new compound between the heat think and the processor.You can even try to use compressed air without opening the portable. Use a clip to hold the fan in place take out the covers for the hard drive, ram, etc and just send air through the side vents and bottom ones. If the machine is not too old (in need of compound too) and if it is not a machine that has been used in a very dusty environment, that should work fine too.
