    Faulty Processor in X61?

    My X61:
    T7300
    Vista Business
    512mb stock + 2 GB (added) OCZ ram
    100gb 7200rpm HD
    Run without battery in the computer plugged in

    My dad's T60p
    T7400
    XP Pro
    2x1GB stock RAM
    100gb 7200 rpm HD
    Run with both battery and plugged in

    When I ran WEI, my X61 gave me:
    Processor 4.4
    Memory 4.6
    Graphics 3.4
    Gaming Graphics 3.4
    HD 5.0

    I got suspicious and ran SuperPi and I consistently get 1:30 to 1:40 for 2 million digits. My dad's computer with XP yielded the normal 1 min superPi.
    This is with all the default Lenovo processes running idling at 773mb memory used.

    I thought it might be the RAM so I tried every RAM combination but no luck.

    Any suggestions? Is it my CPU, maybe mobo?

    The processor is probably not running at its full frequency. Download a program called CPU-Z, and run SuperPi again. Whiles its runing the test, check the processor frequency, as it should be the full 2.0 GHz. If not, then you may need to change some setting under "Power Schemes". A setting of "Always On" should be present, and setting this as defualt, should mean the processor should be running at full tilt under heavy applications.

    A faulty processor will simply not boot up.

    So in your case, you can immediately throw that out as the cause. Like Zero said, make sure it's running at full speed and not throttled back.

    The SuperPi result suggests that the CPU is running at 1200MHz. The balanced power profile should allow the CPU to accelerate according to the load.

    However, what happens when you put your battery in? I'm sure I read of a computer with a similar problem - locked into battery saver mode when the battery is absent.

    This has been discussed several times. There are many Thinkpads that do not run at full potential unless they have the battery installed and plugged in. With te battery removed you will not have full performance.

    I have linked this to a difference between the 90W AC adapter and the 65W or 70W (I forget what the smaller one is). It seems that this is not an issue if you have a 90W adapter. If you have the smaller one you must have the battery installed to get full performance.

    I think those that have nVidia graphics got the 90W adapter and those with integrated got the smaller AC adapter. I suppose plugging in the larger adapter would cure the problem but I have no proof of that. I don't know if anyone has tried it.

    you could also try NHC alternatively im sure you can tweak the setting in there to maximum performance and then check super pi results
    processors usually downgrade their speed to save battery or power usually during battery power yet it is also present while on AC too
    all the best none the less
    yes i echo the statement above saying that a fault processor wont get past the boot check
