HDD activity led stopped working?

    I built this system a couple of weeks ago, have the MSI K8N Neo2 Platinum
    motherboard, in a Lian Li case.

    The hdd activity led was working fine, now all of a sudden it does not. It
    does come on solid, when I first reboot the system, or boot from cold, but
    then after it gets past bios and goes into Windows XP, it stops working
    completely. It was blinking any time the hdd had activity.

    I have double checked my connectors, and they are correct. I tried reversing
    the connector, and it did not work at all, even when posting.

    Any clues as to why all of a sudden it is doing this?

    I have had a couple of Lian Li cases with burnt out led's. You might
    swap the power and hd led connector to see if that's the problem.

    I'll give it a try - it must not be burnt out, as it comes on solid when
    first booting, after posting it goes out and stays out.

    Are you by chance using SATA drives? I found a problem exactly like
    yours with the VIA chipset and SATA, I'm wondering if there's a similar
    problem with the nForce chipset.

    I'm presently using IDE drives and the LED's work as expected.

    I agree on the SATA comment too. Mine only comes on when booting.

    Didn't notice in the thread but did you try clearing the cmos?

    No, I can give that a try as well, thanks.

    Since the LED lights up during the power-up stage, we know that:

    a) The LED does indeed work.
    b) The connector is plugged in correctly as to the +/- polarity of the
    c) The mobo powers the LED during power-up, so by appearance it doesn't
    seem to be a hardware problem related to your board.

    If memory serves, it takes 0.8v to visibly light an LED, reaching
    optimal brilliance at 1.35-1.4v. There's a slight difference in these
    voltages dependant on the color of the LED because different
    semiconductor materials are used.

    If you had access to a volt-meter/multi-meter, you could try doing
    something disk intensive, like defragmenting the drive, and measuring
    the voltage coming off the line powering that LED while the drives are busy.

    That may at least give you a more helpful clue as to whether there is
    a) a voltage coming from the mobo to the LED
    b) a sufficient voltage to power the LED.
