    I think my laptop is overheating

    I have an amd mobile cpu, a duron 1.0 and a duron 1.1. Both cpus are exhibiting the same behavior. The heatsink gets so hot it burns me to touch it, and then after about 30 or so minutes of running it turns itself off. It will not turn back on until I either swap the cpu or let it sit for a while. The fan cuts in and out, so I'm guessing the motherboard doesn't think that the cpu is overheating and thereby not cutting the fan on enough. Since it's a laptop, how can I get extra cooling to the cpu?

    UPDATE: So far, the thing is working well inside. I don't understand it. The only difference b/w the house and car is that the car uses an lcd monitor. (I had the touchscreen disconnected when I tested it)

    The same thing happened with me and my Toshiba A75....The problem was that the heatsink and fan was extremely clogged with dust...I took apart the laptop and cleaned it all out and everything was good as new!

    Air is your friend. Where is the laptop? I mean, where exactly.

    yeah, clean it out and it should work well,

    if you are too scared to open the entire thing up just blow compressed air through the vents, not too much though... the fans will break..

    your best bet is to take it apart and clean it though

    I cleaned the heatsink out about a week ago, but thanks for the insight.

    The laptop is sitting in the extreme right hand side of the trunk. It sits where the cd changer once was. It is getting good air b/c there is nothing below the fan and it should be getting more air here than it does in the house. Its not covered at all. I even took the keyboard off to try and discipate some heat that way (that's how I know the heatsink gets pretty hot, both in the house and outside in the car). Its not hot outside, its about 50 degrees so it shouldn't have any problems in that regard. Any other thoughts? I'm starting to think its not that its overheating. It may be something electrical either with the PSU (carnetix p1900), with the touchscreen monitor, or the usb soundblaster. I don't know if these can make it turn off, though other than the power supply which doesn't give any fault codes or the monitor which i extended its length with a cd changer cable (the factory one in the car). Maybe it has something to do with it. I wish there were a way to check the heat of the cpu to log it to see if its overheating. I'll run it without the monitor and sound card when I get home to see what happens.

    I've actually had the laptop open several times. I've even replaced the cpu in it (the reason I have 2 cpus is that the original motherboard got fried by a faulty power supply).

    if you can leave the cpu+heatsink exposed, put a low profile fan on the heat sink may be from another laptop. the fan can be powered off from usb port with a resistor to convert from 5v to 3v.
