Hi Paul,

     There is a yellow (Device Manager) for "Other devices", "Video
Controller".  The "Device Status": "The drivers for this device are not
installed (Code 28).   This T23 laptop was given to me years ago.  I will see
if I have the driver for this and give that a try.

    I will let you (et al)  know the results after (if) I find the video
driver.

      Thank You again,  John
