    HP Pavilion dv8 Heat Issues

    Computer Specs:
    - HP Pavilion dv8
    - Windows 7 Professional 64 Bit
    - Intel Core i7 Q 820 @ 1.73 GHz (8 CPUs)
    - 8 GBs of DDR3 Ram
    - DirectX 11
    - 1GB Nvidia Geforce GT 230M

    Okay, there's my laptop above. Lately the laptop has started to heat a lot quicker than usual and a lot easier than usual. Basic browsing of the internet causes the computer to heat up. Right now with only my browser open, the computer is running at around 90-95C. FireFox and Windows Explorer are my must taxing processes right now. However, my CPU says that it's load is around 50%.

    The fan is on but it doesn't seem to be going very fast as it isn't very loud. I have cleaned the fan and updated the BIOS and all drivers under Device Manager. I also cleaned out my hard drive and scanned the computer using Malwarebytes, CCleaner, and Norton.

    Does anyone have any idea why the computer could be running so hot when it is basically idle? Also the heat stays around the same temperature when I do eventually run a game, even though that is more taxing than this.

    - Windows 7 Home Premium 64-bit
    - Intel i3 350M
    - Chipset HM55
    - Bios version F.0F

    The fan on my machine behaves the same as yours except that at idle, my machine eventually overheats, locks up and shuts down. The fan speed does not change. It appears that HP, a co-developer of the ACPI specification, intentionally created faulty DSDT tables for fan control in their laptop Bioses. Guess why? To quote the ACPI spec 4.0a document, page 417 section 11.3 Fan Device:
    "The absence of any of these objects (fan specific objects) causes OSPM (operating system power management) to perform ACPI 1.0 style simple fan control." " ACPI 1.0 defined a simple fan device that is assumed to be in operation when it is in the D0 state." I have decompiled the DSDT table for this machine and found no reference to any of the required "fan specific objects". It appears HP intentionally created faulty DSDT tables for fan control in their laptop Bioses. By the way, NONE of the recommended fan control programs have been able to control the fan in this machine.

    Drop coolsense into coolest and put it on a cooling pad. If you want, take it apart and clean out the cooling assembly. I am not sure how much this will help you though. Might be time to send it in for repairs .
