    @tanzmeister - BIOS and EC are both 1.05.05. AFAIK there is no earlier release of the BIOS that was made public, though there is a 1.05.04 EC - don't have access to the changelog from here though unfortunately, I can investigate at work tomorrow if you're not running 1.05.05.

    Do you have the MEI driver installed?

    Also, might sound silly but do you have an external display plugged in?

    The panel won't make a difference, for anyone who is interested here's why in a little more detail:

    The power consumption of each panel, according to the manufacturer is:

    LG: 4.6W (typical)
    AUO 5.4W (max)

    Idle minimum power consumption of the P407 is 10W (this is what it's pulling from the wall through the PSU, not what it is pulling from the battery on battery "mode"). If the system uses 10W with 4.6W from the LG, the AUO could increases the system idle power consumption by 8% - the moment you start drawing more than 10W then the difference that the panel makes to the battery life drcreases rapidly.

    I think I found the problem for battery draining!

    I was using an old Delta charger from gt70, now switched to the original one and got about 40 minutes of Wi-Fi work up!

    still CPU does not throttle down lower than 1.26 on all cores, one of the cores can reach 1ghz though.

    no, no external display.

    It might be worth a reflash of the BIOS/EC.

    does not help, thanks.

    the silliest thing is that when I take ssd Windows out and put it inside p671hs-g - same thing starts to happen, CPU gets stuck at 1.2-1.3ghz. but otherwise p671hs-g throttles to 0.8ghz

    same with OS taken from p671hs-g and installed to p640hk1 - no throttling down to the bottom.

    @XMG perhaps you can test one of your units for me? will it throttle to 0.8 at idle at your side?

    I have asked our testing team to have a look into this, not 100% sure when they'll be able to get back to me as there's a bit of a rush on at the moment before the Easter holiday period. I'll update on this thread when I hear back from them ;-)

    @tanzmeister try using Throttlestop and activate the SpeedShift feature and tell me if your CPU then goes down to 0.8-0.9Ghz :)

    Also activate the "power saving" feature as well.

    isn't that obsolete with SpeedShift, cause EPP is used in that case?

    I'm not sure but it can't hurt, right? It should at least be worth looking into.

    it does not unfortunately.

    funny thing is that when I force 0.8ghz through max speedshift - throttlestop shows more Watt consumption of the package,
