    This strange thing as its a laptop with barely no adjustable option for cpu (actually none) but sometimes its 800mhz and sometimes it 1200 (which it should be).

    There is nothing in BIOS to alter this or redetect ,just changes when it wants basically.

    Anyoe seen this before i have on AMDs but that was with Desktops and usually easy to fix but this is strange.

    Would this be a Centrino lappy?
    Does it show 800 when running off battery, 1200 running off adapter?

    Isnt that just the speedstep (AMD/Intel have diff names for it) technology kicking in and out to save battery life???

    LOL indeed it does but i always use power and sometimes shows as 797 iwht power plugged in.

    I dont have everything Dell installed only Graphics,modem drivers but Bios shows both speeds when power is in.


    I have latest BIOS version also, maybe just dodgy laptop has had a e few issues since i got it.

    afaik isnt the speedstep techology based on system load so it could power down of its own accord whether its on mains or not? Plus isnt it enabled at the cpu/mb level so you dont necessarily need any software to control it? (and may not be able to even control it depending on your mb/cpu?)

    You should check in the bios if "smart speedstep" or "dynamic cpu speed changing" is enabled. This does indeed slow the cpu down when idle. The best thing to do is disable it, and configure your power management to set the cpu speed high on ac, low on battery. I've found that the dynamic speed changing can cause a bit of lag, and make the machine seem a bit slower.
