    Same way you get the 64 bit ones...they're all on the same forums and labelled accordingly. You should be able to find them in their official foruns...

    Thanks for the results. I've been suffering from an intermittent internet connection.

    14-15W discharge rate is fairly high but plausible if you have T series CPU. nvidia GPU and high display brightness. A spike of 29W suggests a burst of CPU activity. If those spikes are short duration then the lower power drain will be dominant and a full battery will give about 3.5 hours run time. If you are not seeing that amount of time then find a sheet of paper then, running on battery, note down the time, power drain and capacity remaining. Change in capacity should be time difference x power drain. If the numbers don't approximately add up and your battery has a sudden drop in capacity part way through the test then it is time to ask Dell for a replacement.

    I normally use a slightly customised version of one of the Dell ControlPoint power profiles which is basically performance on demand CPU speed and drops the display brightness to a couple of steps above minimum. Dell ControlPoint also has various features for extending battery life.

    The chipset has lots of USB hubs. Some of the internal components (eg webcam) use the USB interface. You are allowing the system to shut those parts down if they aren't busy.

    If you choose the right option in the BIOS then you can use the USB charging port even when running on battery. You have to select how much you will let the port drain the battery before it shuts down.

    Hello,

    Could somebody please help me with the following issues?

    - How can I turn the auto-brightness function off? It is annoying.

    - How can I turn the auto keyboard backlight function? I want to turn that on and off when I need it.

    Thanks in advance

    Auto-brightness off (= disabling the ambient light sensor): Fn + left arrow
    Auto-keyboard backlight off: Fn + right arrow

    I went ahead and ordered one. Pre-questions right now:

    Does the backlit keyboard impact battery life significantly if at all?
    How's the fingerprint reader and what is it used for on this laptop?

    There's a small impact on mattery time. You can adjust the keyboard backlight brightness using Dell ControlPoint. My setting is just below middle, which is adequate but not dazzling. The display backlight is a much bigger power drain.
    The fingerprint reader can be used as an alternative to typing in passwords.

    But only for BIOS/boot/windows passwords right? AFAIK, website passwords etc cannot be replaced by finger swipes... at least I found no way of doing it.

    Please reply quickly, I just advised an E6400 buyer to not get the fingerprint reader because of that...
