No backlight on a Dell Latitude D520

    I work in the IT department of a school. And we recently bought some
    Dell Latitude D520 laptops for some of the teachers. Most of them work
    exactly as expected and we're amazed with the battery lifetime, 6

    Sadly, like we've experienced before, a few Dell laptops get faults.
    But thanks to Dell's great support, we get the problems fixed pretty

    This laptop I'm having trouble with is completely new. But when I
    turned it on, the backlight didn't work. While hoping to fix the
    problem afterwards, I managed to go through the setup wizard correctly
    and log in to Windows XP. I tried adjusting the screen brightness but
    it didn't work.

    Since we're still setting up Laptops for the teachers here, we plan on
    getting that finished before we call support. But until then, any
    solutions to the problem are welcome.

  2. Hardware problem, fixed under warranty. You could try bouncing the
    switch at the base of the lid that knows when the cover is closed, but
    it's really not _your_ problem, it's Dell's problem. If you are still
    within the 21(?) day purchase period, tell them you want to send it
    back and get a brand new one in it's place.

  3. Call support. The backlight inverter has probably failed. It's also
    possible that the backlight lamp has failed or broken (and yes, you can
    break the lamp without necessarily breaking the screen). This could
    become a huge expense (Dell won't replace a bad backlight, they will
    replace the entire LCD screen), it's a brand new unit, don't mess with
    it, it's not your problem it's Dell's.
