IBM T20 screen flicker

Discussion in 'IBM Thinkpad' started by Mitchell Regenbogen, Jan 10, 2005.

  1. I have a T20 with upgraded 40GB drive, 512MB memory, etc. Works
    fine. However, the screen flickers intermittently but only when
    connected to A/C power. I know it's not a Windows XP issue because
    the flicker will also occur in the BIOS setup screens. Knocking the
    screen down in brightness a notch will usually stop the flicker for a
    while. It never flickers when on battery power, even at the
    brightest screen level. Can anyone tell me if this is an LCD issue,
    battery problem, or A/C adapter problem or something else? Thanks.

    This is probably a problem with either the backlight or the inverter
    that drives it.
