    Hi There,

    Here is a challenge for you. I just bought an ASUS z71V, with one of the main reasons for the purchase being to run Pro Tools LE. I've installed it successfully, only to find that as soon as Pro Tools loads up the CPU usage jumps to 100%, creating constant fan noise and, obivously, a lot of heat. I finally stumbled on the Digidesign user forum and it turns out that I'm not alone. Apparently Pro Tools uses the cpu clock to keep everything in time, and Speedstep (or similar technologies) mess with this. So they make all us PC laptop users run at 100%!!

    Here is a suggestion on a possible fix for this problem:

    << While we wait for the real solution, why not tell us what registry key(s) we have to change, to fake your PTLE installation program into thinking, that we all have a normal Pentium4 processor - allowing our mobile CPU's to take a break from this ridiculous situation. >>

    The idea is that we can then turn off power saving in windows and the problem will go away. Any one out there with a clue on this one? You will surely gain fame and fortune over at the digidesign forum.

    Cheers

    If your notebook is plugged in, then go into the Control Panel, and set the power settings to "Portable/Laptop". That makes the processor run at it's maximum core frequency all the time (except when on battery, then it's impossible to override).

    I'm not in front of my notebook now to try that out, but my understanding is that Pro Tools somehow checks for the processor type. Turning off speedstep doesn't seem to have helped any of the other poor souls with this problem....

    Nope, that didn't help either. Anyone else with any thoughts or ideas on where else I could get an answer?

    Try CentrinoHardwareControl - CHC - I believe in there you can set the laptop's processor speed up to whatever you want. CHC also allows you to tweak a bunch of other settings. Pretty good program! ;)

    Thanks chazman.

    I've installed CHC and can throttle my speed back to 800 Mhz. Pro Tools now recogises this as the maximum speed. While it still thinks the CPU is running at 100%, it is actually running at 800MHz and not 1.86 Ghz, which means it generates less heat. Should tide me over until digidesign sort out this stupid situation
