    I've got a Presario R3240US Notebook. With the computer proped up at a 10 degree angle on a non-pourous surface, Everest monitered my CPU running at 42 degrees C (108F), with 0% CPU utilization (Everest and startup programs only). I ran diagnostics because, when running the computer with higher CPU loads, it often shuts down without warning - I assumed it was a result of overheating. My warranty with Compaq has expired, but I still have 2 years left through Circuit City. Unfortunately, that would require me sending in my computer for 3-4 weeks. Any suggestions on resolving this problem without resorting to Circuit City?

    I know nothing about working on a notebook, I can only say what I would do with a PC, With a hot CPU, the problem is either bad air circulation or poor contact between the CPU and heatsink...assuming that there is such a thing on a notebook. The first thing to do is to check the cooling, which means seeing that all of the fans run properly and cleaning any dirt from the fans, heatsink and case. If this doesn't help, then reseating the CPU might, but then most people would leave this sort of thing to a professional, because notebooks and PCs are very different critters.

    42C is not a dangerous temperature.

    No it isn't. But it may be getting alot hotter under load.

    I started the new thread to better answer common questions - just should have edited the original post, I guess. Anyway, my logic is that if my CPU is running at 42C idling with the fan working properly, then when under full load it must be getting MUCH hotter in order to cause a system shutdown. I'm guessing, with full load, the CPU is getting around 40-50 percent hotter than its idle temperature. The fan ports are all free of dust, as well, and I have tested using a household fan to circulate the air around the output and input ports as well.

    So what kind of temperatures are you seeing under load or when the system restarts?

    Thats not necessarily a correct assumption. Many laptops have temperature controlled fans, as the temp goes up the fans speed up to cool down the system.

    You might also think about investing in a laptop cooler to sit under the laptop. Mine shuts down every now and then if I'm watching a DVD, and have things running in the background.

    And just for clarification, I've seen studies that fans don't really make much difference--as long as you have the laptop up on something so air can flow all around it, it will be cooler. Not that there is anything wrong with the fans on laptop coolers--it certainly can't hurt. Just make sure if it has fans that it has a USB pass through because otherwise, you lose a port to plug in the laptop fans.
