    its more when you turn off powerplay (thats ridiculous) and set energy management to minimum... i got about 5 hours then. but you cant work with that performance. excepted with office. but i didnt buy a precision for office applications ;)

    so i really hope dell is updating the drivers soon.

    Hi all,
    This is caused by the timeout of the panel(MC6JN A00).
    You can ask for a replacement of a new panel(MC6JN A01 or other panel).
    The issue will be solved then.

    Did your notebook have this issue?
    You can get the Panel Revision from the back of the panel.

    Yes.

    I just did a bunch of tests.

    All tests were done with active power plan: power saver.

    Enable Power Play: Yes
    Monitor Hz = 60
    GPU core = 250 mhz, min 100 mhz, max 400 mhz

    Enable Power Play: no
    Monitor Hz = 60
    GPU core = 100 mhz, min 100 mhz, max 400 mhz

    Enable Power Play: yes
    Monitor Hz = 40
    GPU core = 100 mhz, min 100 mhz, max 400 mhz

    Enable Power Play: no
    Monitor Hz = 40
    GPU core = 100 mhz, min 100 mhz, max 400 mhz


    So when I use power saver plan, only when my LCD screen is at 60 hz refresh, enable power play that the bug exist, all 3 other possibility will downclock the GPU to 100 Mhz.

    With the LCD panels, does a change from 60hz to 40hz even make a change that is noticable to our eyes? When I decrease mine to 40hz I think that I might be able to see a difference but I think it's just my mind telling me that i should be able to see something different.. technically though is there a difference that we should be able to pickup?
