How to prevent laptop overheating and death without spending ANY money!
I'd shown my friend a no-cost method to clean it a couple or three years ago, but she must have stopped doing it as it just died again and so I'm re-repairing it. I was emailing her these instructions to print out and keep with her laptops to help keep them alive. It then dawned on me to post it here to help others to keep their laptops alive as well. Enjoy!

The dust gets sucked inside the laptop when it is turned on and it must be cleaned regularly to prevent unwanted downtime and repairs.  The following is a procedure anyone can perform without tools:

  1. Every 3-4 months, shut down, close and unplug all cables from your laptop.

  2. Pick it up so that the bottom of the laptop faces away from you.

  3. Identify the opening on the side or rear; Wherever the hot air normally comes out.

  4. Place your open mouth against that hot air port, sealing your lips against the plastic.

  5. Forcibly blow air into the laptop as though you are performing that lung capacity test at the doctor's.

  6. Notice the plume of dust which is emitted from the bottom of the laptop as a vortex.

  7. Repeat step five, repeatedly, until no more dust is emitted.

The longer you wait between performing this cleaning, the thicker the plume will be, but the less complete the cleaning will be as accumulated dust can become impacted and unwilling to move. Permitting enough dust to accumulate will increase the chances you laptop may need an expensive repair or even replacement. Canned air does NOT do a better job than my method. Please do this outside if you live with anyone who has allergies, as this dust is really vile.

I have been asked if the moisture in your breath is a problem, such as in cold weather when condensation might form inside the laptop.  Condensation only occurs when the laptop is cold, so only perform this on a laptop which is at room temperature.  As for doing it in the winter, it is SAFER to use your breath to clean a laptop, than it is to use dry air.  Anyone who has ever gotten a static electric shock in winter knows that dry air permits static charges to form, which moist air, such as what you exhale, will prevent. What you may not realize is that dry air can also generate static charges rather like rubbing a balloon on your hair.  Moist air will not do that, or at least it will tend to bleed off the charge before it can accumulate.  So you see, my method is not only cost effective, it is also better.

In case anyone is wondering, yes I actually do use compressed air in winter to clean larger desktop computers where my breath is inadequate.  I mitigate the risks by using a pressure regulator and use lower pressures than I would in summer when the risks are lower.

Typo:
"dry air permits static charges to form, which moist air, such as what you exhale, will permit."

That should say "which moist air...will prevent."

Yes, tamar_lindsay, you may. Or you may post them the link to the public version on G+ which also probably needs correction. Good thing I didn't post it to Facebook as it does not permit me to edit things.
