Question

My laptop a HP

Answer 1

Try cleaning it out, especially the vents where air comes in. There should be atleast an intake and exhaust vent. Also make sure your power supply fan is still working.

Answer 2

Depends on what make and model you have.

Some laptops are "desktop replacements", so called because they have a CPU normally used in desktop computers, which produces a lot more heat and eats more power than a "mobile" CPU. If yours is one of these this might explain it.

Some heat is normal, but if it's hot to the touch, you may want to power off the laptop and take a can of compressed air and use it to blow any dust out that might be retaining heat inside the casing. Blow carefully around the vents especially where the hot air is vented out.

What makes a computer’s case get hot, how to prevent it, how to alleviate it.

Does your computer act strangely after it's been on for a few hours? Does it lock up unpredictably, or seem to get "slow" - and are the problems worse in the afternoon (or the summer)? Does giving your computer a "rest" improve the situation - for a while, anyway, until the problems surface again?
The simple fact is that more computers suffer heat-related problems than most users recognize. Your computer's stability and speed can both be affected when heat builds up inside its case, causing crashes in odd circumstances and hampering performance. Even if your computer seems to be running fine, it will probably fail prematurely if it's running hot. Antec's editors have come up with a list of things you can do to help your computer beat the heat.

Mine used to do the same thing. You get a canned air duster (can be found at any computer place or department) and spray it in the back by the fan. It's all clogged up with dust. Good luck! I used to have to use a cooling pad and everything, and it even heated the cooling pad, but now it's great I just felt the bottom of it and it's barely even warm.

Answer 6

It is working. All those little electrons running around in there starting and stopping and making decisions create friction. Air has to go through there and take the heat away or it builds up. Make sure the fans are working and not clogged up.

Answer 7

When you say so hot, what kind of temperatures are we talking about? If it's just warm to the touch it is ok, as any electronic device will get warm when used. If it is causing burns than there is a problem and you should post more information so I can help you fix it.

is this a laptop? is it sitting in your lap? you should not do that unless it is sitting on a hard surface like a piece of plexiglass, plywood etc. to induce airflow around the bottom of the computer.
