Why do those spray cans of air that clean out your computer keyboard get so cold?

law of conservation of energy\nany gas that is compressed will 'lose' its heat energy to the ambient temperature in the process (ie a refrigerator). in the specific example the gas (1 cm3 at 70F )is at room temperature until its expanded to lets say 1000 cm3, now 70F is spread out 1000x the area,(as is the gas in the can) the more the 70F is expanded the 'colder' it gets (much like the universe or a car tire, but its all relative)

You might be able to save it. Don't turn it on while it is wet. Take out the battery and all removable drives. I have always used Isopropyl alcohol on wet electronics to try and expunge the moisture. It really works very well. This will also get rid of the stickiness on the keyboard. Let it dry completely after using the alcohol.

I am weird, I clean my keyboard and mouse with rubbing alcohol pads and my desk with Lysol wipes. That was before I found about that story about the bathroom. Dirty computer equipment has always bothered me. I have scrubbed old beige monitors with Comet cleaner..works real good!

It may be from dust build up.  A lot of cheap laptops have internal setups that hold a lot of dust in. You may want to try and buy one of those compressed air cans and spray thru the vents in your laptop every once in a while.

Well I always grab my q-tips and a bottle of rubbing alcohol or some mild cleaner and yes I do every key individually. If I have a lot of dust and such between the keys I vacuum the keyboard. Some people I know use the air in a can method, or they just flip the keyboard over and whack it a couple times.

Get a new keyboard.  Not that dear & not covered in kitty poo / sick.  I can't imagine how you'd clean that.\nJust realised you meant water.  Leave it to dry somewhere warm, but no direct heat.  Leave it for a couple of days perhaps.  As long as it's just water & not waste should be ok.

A computer can also "freeze" when it overheats.\n\nIf you are comfortable working with computers, UNPLUG yours, open the case, and use canned compressed air to blow the dust out of the case.\n\nYour memory may have errors, causing lockups. Not having ENOUGH memory can result in slow loading programs, as can a slow, fragmented hard drive.

Well, it's time to clean it. Go to the store- any store that has techie stuff - and get some canned air. Bring it back. Turn the thing upside down and tap it on the table. Damn! Look at all those crumbs, chocalate crumbs, jelly and assorted coffee blots! No wonder your keyboard sticks. Blat the living crap out of the keys, inside every crevice you can. \n Don't take the advice of those who will inevitably say you can hose it down or put it in the dishwasher. I am a fan of hosing all kinds of electronics, fans, etc., down. But not keyboards. They don't like water. Stick to the canned air.

Because all cold air is created in the freezer. The fridge gets cold by leeching off the freezer.  There is only one compressor. Cold air sinks, so it falls into the fridge.\n\nUnits like side by side and bottom freezers need a fan to get the cold to the fridge. A top freezer doesn't.

Actually they no longer give off the "bad" CFC found as in the past!  One can of the keyboard cleaner that you buy at Walmart actually has around 2 times the new Freon (R134) in it that the new refrigerators  have in them!  AND YOU SHOOT IT INTO THE AIR! HOW ABOUT THAT!\n\nSo I guess that old refrigerators are a small problem and refrigeration in general in third world countries,  where they do not have to follow the conventions!  \n\nIn modern refrigerators there are few disadvantages!  Compaired to cooling your whole home or a huge office building!  Thats where you run into the enviornmental potential!  Not the little refrigerator, no matter how many!\n\nOne office building can easily have over 3000 pounds of refrigerant (R22) involved this if it escapes can cause harm. If the office catches fire, then all sorts of poisons are released into the air!\n\nThink of how many cans of keyboard cleaner you have used!\n(Freon is why the can gets so COLD!)  Each individual can would fill 2 refrigerators! \n\nKinda puts it into perspective!\n\n\nHave a good day!\n\n\nAPS

I can only think of 2 things that may be wrong, \n\n1) The laptop could be overheating, this can be caused by working on a soft / padded surface such as a cushion, carpet. what happens is that the padding conforms to the shape of the laptop and presses against it, blocking the vents that the laptop fans need to cool it efficiently. try propping it up by using something under the 2 back corners like a small eraser or something that will lift it up from the table/surface. Also try and blow your fans out maybe theyre dusty- use the spray air cans.\n\n2) Check your power management settings, Go to Control panel, power options and see if there is anything there that will help you, the options are pretty straight forward.

No.\nThe computer works better when it is warm.\nIt's a hardware thing.

OOPS! Your keyboard inards are made of mylar (plastic film). If the pop has gotten into the film layers it needs to be disassembled. The mylar layers can be cleaned with a very mild soapy water. I wouldnt use alcohol as it may remove the circuit trace. Laptops are a PAIN to disassemble. Find someone who knows how to do this.

They pump the cold air out leaving only the warm air.

you will get more dust if the case is open.\n\ninside the case you will see a series of circuit boards with exposed silverish pieces all over them.  These pieces are taking on an electrical current, and thus have a magnetic charge.  Its this magnetic charge that will attract dust into the computer.  Opening the case will turn your computer into the equivalent of one of those "ionic air purifiers"... except it wont be any good at it.
