Yes, I replaced the batteries on both towers. The fact that both towers are
trashed with similar failure modes (although one now doesn't receive at all) and
stopped working at approximately the same time suggests an external agent
causing the failure. The only change in the use environment that I can ID is
the computer - I upgraded to the Win2k box. The sequence of failure is even
more suspicious; my at-home Mindstorm system failed, so I borrow the tower from
the system we're using at work for robotic research and verified that it was my
tower that was bad, and now the work system's tower is failing. My suspicion is
that, by unplugging the tower, you saved the tower from permanent damage.

| Greg, of course you tried putting in new batteries first, right? Most of the tower problems can be resolved by putting in a new battery. The green LED will still light up even if the battery is too weak to allow proper communications with the brick. (...) (23 years ago, 4-May-01, to lugnet.robotics)
