Just When You Had It Figured Out: Common Computer Maintenance Misconceptions Part 3

Don't stick your vacuum right inside your computer
Make sure you don't use your outside vacuum to clean the inside of your computer!

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!

Just When You Had It Figured Out: Common Computer Maintenance Misconceptions Part 2

There are many kinds of canned air, make sure you get the right kind
This is NOT for cleaning your computer. Remember: Oxygen + Spark + Dusty Air = Inferno Tornado!

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! ⌂

How To Replace a Keyboard Key On Your Own

Sometimes keys fall off of keyboards due to age or excessive wear.  If one or more keys fall or break off of your keyboard, we have keyboard repair tips for you!  You can most likely fix your keyboard on your own without having to buy a new one.  There are no universal guidelines since all keyboards are different but here is a general step-by-step guide on how to put back a missing key back onto the keyboard.

Replace a Keyboard Key On Your Own

Step 1:

Remove the work key Form Key so that only the cover comes off, leaving the inside intact. This will help you to know exactly how the broken key should be put back.

Step 2:

Identify the Key Retainers (small plastic parts) that hold the rubber gasket in place.  Most likely there will be two pieces that interlock together and snap in place at four different points. Use tweezers to gently lift the retainers up and make sure you take into account how they link and where they snap together.

Step 3:

Similarly, use tweezers to unsnap the retainers you need to replace the rubber gasket underneath. Start by separating the outer retainer from inner retainer, one side at a time. Finish removing the final gasket by softly pulling it out with your fingers.

Step 4:

Assemble the plastic key retainers to reassemble the working key if the retainers are being replaced. If the rubber gasket needs replacing, remove the worn piece and replace it with a new one.

You can buy individual keys or rubber gaskets on eBay or Amazon.

Step 5:

Push the key retainers gently over the rubber gasket until it snaps into proper place on the keyboard. Follow the reverse procedure starting with the retainers, link them together, snapping one end in at a time, sliding the retainers over the gasket and then snapping the other end onto the keyboard base.

Step 6:

Snap the key cover back on. Gently push until you feel the key cover snap into place.

Computer Cleaning Tips

Computer Cleaning Tips

Dusty laptops/computers tend to overheat and as a result they may restart automatically or not function properly.   When a lot of dust and dirt builds up inside the computer, the computer will stop functioning properly and may need to be taken in for a ‘repair’ job where technicians must take the computer apart and perform a deep clean to get the computer to run properly again.  As preventive maintenance, here are some tips on how to clean your computer, keep it functioning and running safely, and avoid taking it in to the repair shop.

Computer Cleaning MaterialsCan of Compresses air, cotton buds, cloth

  • 1 Can of Compressed Air
  • A Few Cotton Balls
  • 1 Soft Cloth
  • Cleaning Fluid

Before Cleaning

Make sure your computer is turned off and unplugged before you start cleaning your computer.  This ensures that no part of the computer is harmed as you clean it.

Steps to Clean Individual Components

  1. Blow away the excess surface dust with a can of compressed air.
  2. To clean the keyboard, use cotton balls to remove large particles of dust between the keys, then blow away smaller dust particles with the can of compressed air.
  3. Wipe the surface of the keys with a damp cloth but ensure that the cloth is not excessively damp as fluid can damage the computer’s keyboard.
  4. Put a small amount of cleaning fluid on cloth and gently clean the screen.  Make sure you don’t apply pressure while cleaning the computer screen.
  5. To clean the ports on your computer, carefully wipe the inside of each port with cotton balls and then spray each of them with compressed air.
  6. To clean the computer’s fan, hold it and spray it with compressed air.  If you don’t hold it, the air will cause it to spin and could break it by making it spin faster.
  7. To clean the DVD or CD Drive on your computer, open it and spray the compressed air inside.

Speeding Up Your Slow Computer

What makes your computer slow ?

Often times you might ask yourself why your computer is running slow.  When people bring in their computers and laptops for repair this is one of our most often asked questions.  Read below for common problems that will cause your computer to run slow and easy solutions to speed your computer up.

What makes your PC run slow?

  • Constantly working with a lot of files (moving, copying, deleting) will slow down your computer and use computer processes that are reserved for other functions.
  • Similarly, keeping several computer programs open at once can bog down system resources.  This is true, especially for certain programs that perform higher end functions, such as image manipulation programs – like Adobe Photoshop, movie editing programs, and design programs.  Video game programs can also slow down your computer system.
  • The computer’s processor speed is a factor in many cases.  Each computer is limited by its hardware (the processor) to the number of simultaneous functions it can perform.  If you are running or editing multiple programs or files, as described above, your processor will get bogged down and not be able to perform the needed tasks.  Your computer may simply have an outdated processor or the tasks you need to perform may outpace the ability of your computer’s processor.  The computer engineers at LaptopMD can look at your computer and, based on your needs, we can recommend a new computer processor which will help you perform at the most efficient level.
  • Related to processor speed and multiple computer processes, your computer speed can be affected by the computer’s RAM or the amount of available memory available to your computer.  All programs and tasks take a certain amount of memory while in use.  The amount of RAM can be increased in most computer models to allow for more user activity on the computer.
  • Windows, program, and other computer animations can also slow down your computer.  Playing video games, watching videos online and running programs with intense animation may take a lot of processing speed and use large amounts of RAM.  Animation is a common problem that can significantly slow your PC down.
  • Cookies, registry processes, and an internet browser’s cache are information files stored by programs to remember internet preferences, program settings, and other temporary files.  Over a period of time, these can accumulate and slow your computer down.  To prevent the cache, cookies, and registry processes from slowing down your computer see our solutions section, after the jump (click the ‘Read the rest of this entry’ link below).

All of these problems can be remedied either by modifying your computer’s hardware, talking with a computer expert (at LaptopMD), or by reviewing our easy solutions section after the jump (click the ‘Read the rest of this entry’ link below).  Reply in the comments with any questions you might have and we’ll help you out!
