    My BIOS has no provision for changing clock speeds. Does anyone know of any utility that can manage under clocking?

    Which operating system?
    Some very basic memory and processor underclocking may be done from within the operating system's advanced settings
    if the right hardware is present.

    Peter,

    Most laptops do this via the Power Management setting.

    Hi,
    Thanks for both your responses. The pc is an Acer five year old Aspire 5000 laptop running XP Pro SP3. There is nothing relevant under Power Management. Clint - where did you mean by the OS's "Advanced settings" please? I have had a good look round most places without finding anything.

    msconfig; Number of processors, Maximum memory. Not a true underclock in the conventional sense.
    Why would you want to underclock? Are you experiencing heating issues?

    OK - yes I found the equivalent under XP's msconfig thanks. However there is only one processor and limited memory to start with so this did not take me very far. Re, "why" - short version is "yes, heating". The fan died and replacing it cost more that it was worth. I have fitted an external fan which generally works pretty well, and the laptop is now relegated to backup management only. Some large scale dumps take the processor into the 70 odd deg C range. There is no timing issues associated with it's work, and since it switches back and forth between 800 Meg and 1.6 GHz I know it can work at both rates.I would be quite happy if it sat at 800 MHz permanently.

    If your not willing to spend the money on a replacement fan you will be forced to deal with the temperatures.
    I would not rely on this machine for backup, or anything else for that matter.
    For all intent and purpose it is broken.
    The only true clock adjustment settings are in the BIOS, but most laptops don't allow for voltage changes.

    OK, thanks for trying. Fan replacement $150 - new Netbook $220! So now I travel with the netbook.
