    Looking at my WEI (I know it's not a great benchmarking tool, but it's there and everyone understands it) and trying to increase some of the scores, I decided to increase my RAM voltage from 1.5 to 1.7 in the BIOS.

    Ran the test and the score rose from 7.3 to 7.5 which was good.

    However, all afternoon, either when I leave the laptop alone, or I put it to sleep by pressing the power button, when I turn it back on again I just get the lights and fan. I have to power drain to get it back up and running again.

    I've switched the setting back to 1.5 for now - not really fussed.

    But why does this happen and does anyone else experience the same thing or know how to overcome it?

    Cheers

    Hmm, at least you got it working.

    When I set the RAM to 1.6 and saved the BIOS configuration I got in an infinite boot-loop. I had to remove the CMOS and reset the BIOS to get it working again.
    What RAM do you use? Stock?

    About WEI... that the RAM went up from 7.3 to 7.5 is not necesarrily because of th increased voltage... if you run it again you might end up at 7.4 or something similar, that's WEI, at least how I experienced it.

    yup you have to reset the bios like svl said. the M15x doesn't like any kind of voltages changes to the ram.

    Stock RAM yes.

    If it doesn't like the increase, why do Dell put it in the BIOS? Weird!

    Anyway, at least I had was able to recover from it without too much of a headache.

    Cheers guys.

    WEI is terrible for gauging performance.
