    XPS 1730 cpu throttling back

    My xps m1730 has seemed a little sluggish since i originally recieved it back in july. Its a 2.4 with 4 gigs of ram, and the 8700 gt (non-sli).
    I have and still continue to have problems with the power adapter being recognized even after flashing the newer a9 bios.
    As I said I suspected something was not right, and after doing some examining with tools i have discovered some things.
    Running cpu-z to monitor the processor..

    When i place it in high performance mode and unplug the power adapter, the multiplier is at 8x for 1.6 and 1.038v, occasionaly "bounching" to 2.4 but never staying. the cpu will not chage to full performance even when doing intensive web sessions and video.

    Next, re-connecting the power adapter the multi immediately drops to 6 for 1.2ghz, and voltage bounces between 1.038 and 1.338v. Again occasionally the multi will bounce to 8 (1.6) and rarely (2.4) but never stays..even with video or intense web browsing sessions.

    I know this is not normal, and the only thing i can guess to is something to do with the motherboard not receiving proper voltage by being damaged or psu damaged.

    Any ideas or help would be appreciated.

    i wouldnt say anything is wrong yet,
    did you check the windows power options.. there is an option called processor power managment, where you can select the minimum and maximum processor speeds when plugged in/on battery depending on your power plan..
    this is in vista only (i think) where to save power on battery it selects a few power saving options to get a little extra battery life, those options could be changed to your preference

    Just found and checked these settings, Min was set at 5% (just bumped to 100%), for battery and 100% for all the other 3, min plugged in, max plugged in, max battery.

    No change.

    Have you put a call into Dell ?, I would do that first.

    As your having issues with the power supply being recognised, its sounds like a Mobo issue to me. I've owned my 1730 since Dec '07, and never had any issues with the power adaptor, infact once plugged in its very secure indeed.

    yah! i guess you can call DELL first. there's definitely a problem with your laptop.

    try running some benchmarks also to compare performance with other references.

    there might be a problem with your mobo alright.
