It turned out that the power cable going from the power supply to the UL had
an intermittent open somewhere. I replaced the cable with half of a
Macintosh printer cable. The connector seems to match the UL "DC IN" port.
There is a pin where the original UL connector has a plastic plug, but this
doesn't seem to matter. I may use the other half of the Mac cable for an
external battery pack. Thanks to all who suggested that the cable could be
the problem. (1 message quoted below.) I find it interesting that others
have had the same problem. I wouldn't have suspected it, since it showed no
external signs of damage.
