fan not working?

[kayaboy]

I have a Dell Dimension 1150 laptop, running XP Pro with a P4 processor and 512 mb RAM...just after burning a CD (data) the other day, I found that the cpu wasn't working properly--it sounded like it was running but there is nothing showing on the screen...when u hit the power button it looks/sounds as if it's turned off, but when u barely hit the power button again it turns 'on'---although it seems to be 'hibernating'--sounds like something's running, but nothing's showing... there is nothing showing on the screen, nor do the indicator lights for the wireless card blink, as they normally do when powered on/connected to network...
I've been told that it could be the fan not working anymore, although I do hear what sounds like the fan running...it has overheated/shutoff in the past when we've left it sitting on the couch, and/or on a pillow.
what could it be?? any ideas would be greatly appreciated!!!!

I would check total system cleanliness. Canned air, soft brush, etc.

The fan may be turning, but may not be functioning efficiently. A through cleaning might be first in order.

If you are not comfortable doing this, have it done.

Check the openings that you can see first to see if they are blocked or semi blocked with dust etc.

Hope that it is just this

I always recommend users do not position a laptop on soft furnishings like carpets, pillows, or even for lengthy periods on their laps! Main input for the CPU fan is invariably on the bottom of the case, so partial blocking can easily lead to overheating.

Cleaning is a good place to start as mentioned. Also, as a test, you might want to try powering on with the hard drive removed. My experience with laptop repair is one that has found that continously higher than normal heat levels reduce the life of the hard drive. This of course depends on the location of the hard drive as it varys.
