    I think it's a more generalized hardware fingerprint based on the CPU gpu and mobo

    So since we had an accell display port hub laying around we wanted to see what happened if we used one on the first DP. On the dock. Turns out that disabled the second DP on the dock. It doesn't make sense but just an fyi MST Hubs disable the second DP on a dell dock.

    Is there any way to overclock the Nvidia K2100M beyond +135MHz?

    You will need to flash the VBIOS with a clock unlocked variant to overclock the K2100M more than 135 MHz. You can take a look at this forum, if there is no unlocked version available already, someone can mod it for you if you dump your current VBIOS and upload it there.

    (I'm running K5000M overclocked using a VBIOS that I got from there.)

    If you replace a "regular" palm rest with the fingerprint reader palm rest, the fingerprint reader will work.
    The fingerprint reader is attached to the motherboard with a separate ribbon cable but all motherboards should have the receptacle for it. It looks just like one of the other ribbon cables (touchpad or keyboard, can't remember which).

    I'd say no... Under general use, faster memory won't make a perceptible difference.

    Thank you.
    On desktop PC I was able to OC ddr3 from stock 1860 up to 2000.
    Throughput went from ~18 to ~30 point, acording to AIDA64 memory read bench.
    Can I repeat same trick with m4800?
    I do not have laptop in my posession yet so I cant see the BIOS settings yet.
