    A thin pink line started appearing on my screen

    I've got a T400 (like my signature says) and last night I saw a 1 pixel wide, pink vertical line on my screen. It went away & came back and is currently gone; I don't believe there is any action that can reproduce it.

    So - anyone had this before? (will search site right after this) Is my monitor dying? Worse - could my laptop be showing signs of death? My smallest hope is that it has something to do with going in & out of Sleep mode rather than totally powering up & down, but I'm not holding my breath.

    Are you using a docking station? How is the monitor connected?

    It's the screen on my T400 - not an external monitor. I do not use a docking station. My guessing process:

    1) something weird with Sleep mode messing with the display drivers (my hope)
    2) something with the display drivers
    3) something with the display hardware
    -- I have the switchable graphics, onboard & ATI (using onboard atm - just switched in BIOS *and* turned off ATI in BIOS last week)
    4) something wrong with the motherboard affecting the built-in display hardware
    5) something up with the screen itself and/or its connections (not likely, I'm guessing - I'm not rough with it)

    That's what I was going to ask: "Is the machine in warranty?".
