    Undervolting doesn't get rid of Power Limit Throttling, IMHO.

    It improves maximum sustainable speeds during extended stress periods, even if the CPU overheats.

    PL throttle can be solved with lowering temps, since silicon likes low temp and is more power efficient that way. Though the effects on laptops that can only drop a few degrees after repaste is questionable.

    I have already repasted and have seen a significant drop in temperatures; also got rid of thermal throttling.
    But now this PL throttling has come up which wasn't there before.

    You were likely thermal throttling before and now you are running into power limitations. It's common, at least you're getting more speed out of it. An undervolted CPU uses less power and will run faster before it PL throttles. You may be able to change your power limits with Throttle Stop but you'll likely hit the thermal barrier again.

    You can use throttlestop to set TDP UP (level 1), try it out.

    Couldn't get you brother....Can't I use XTU for adjusting TDP?

    So now that this one's been out on the market a while, how is the display? Are the dimness complaints mostly exaggerations? And did Lenovo ever fix their touchpad firmware so it turns off when a mouse is plugged in? Coming from a T450s, the latter issue really bugged for a while.

    You can use throttlestop to change the TDP level to 2 (44w). Not adjusting manually, it's a setting preconfigured for the CPU.


    You have a touchpad setting that can do that IIRC.

    If you want a decent display, get the WQHD one.

    I have a WQHD panel and it is very good. Matte, accurate color and very very comfortable to work with for extended periods. Stay away from the FHD panel....I have seen it and its absolute trash

    Alert!
    There is a new Bios update 1.30
    It solves much of the throttling and heating issues!
