    The cooling system is adequate but if you put the notebook on a laptop cooler that improves the airflow to the intake on the bottom then I would expect the temperatures to be kept a little lower.

    Some people have reported coil whine problems and had Dell replace boards. If mine suffers from it them my hearing is worse than I thought (ie I can't hear any whine). Perhaps it is a lotter or perhaps it is something fixed on newer boards.

    Did anyone manage to jump through the right hoops to be able to adjust the keyboard backlight timeout?

    A post earlier in this thread refers to some advice from 2009 which somewhat pre-dates the E7440. Discussion here refers to the feature Enhancement Pack. Did anyone try it?

    I tried installing the Feature Enhancement Pack - APP_WIN_R312092 and it failed under Windows 8.1. It asked for .NET 4.0 which is already installed.

    It seems as if Dell have made a backwards step with not allowing the timeout setting to be changed. I’m going to test it over the next few nights to see if I want to keep it.

    I managed to get FEP version 2.2.0 to install and then updated it with 2.2.1.

    However, it doesn't install any controls for keyboard settings. I'd like a 30s backlight timeout - the default setting is too short and the keyboard goes dark whenever i stop to think.

    I found the keyboard backlight timeout controls by installing "Dell System and Devices Manager". I don't recall exactly where I found the download, but it gives me the option to have 30 second timeout.

    I agree with some of the earlier posters that the touchpad leaves a lot to be desired. It will skip across the screen occasionally and the two-finger scrolling is really bad.

    The only other issue I've had is that occasionally if I'm streaming Pandora in a browser and go through a few cycles of pausing and playing, eventually the audio will stop playing through the headphone jack. It plays through the built-in speakers just fine, and windows recognizes that audio is playing, but it won't come over the headphones until I do a restart. Anybody else experienced this issue?

    Thanks, are you using Windows 7 or 8.x?
    If you still have the download please share the name as it might help find it.

    Thank you so much and working fine with me on an E7440 under Win8.1.
    Spoke to Dell tech support this morning and they were clutching at straws so I'll tell them the solution tomorrow. :)

    Ok, so the throttling seems to happen when either the GPU hits 60c, PCH hits 75c, or auxiliary hits 46c, going off HWinfo.. does anyone else hit these temperatures?

    And working OK for me (E7440, Win 7 64-bit) adequately after a reboot provided I just set the time I want on the pull-down list and don't touch the Turn On button.

    Thank you for pointing to the right software.
