No, there is no way to tell as far as I know. I believe the choice of
power source is done by circuitry, not logic.
I do believe that the external power supply is used in preference to the
batteries, but this might not really be the case - you might still drain
the batteries somewhat even if you have if you have an external power
supply. At least, I left my RCX plugged in with batteries, and I believe
my batteries eventually needed replacing, even though I almost exclusively
used the external power supply.

| I think the RCX will use which ever supply voltage is greater. I havn't tested this, but I'll bet that when you plug the AC adapter into the RCX when the AC adapter is not even plugged into the wall the RCX will still work. This means there isn't a (...)

| Hi, How does the RCX handle things when there are batteries installed and it is also plugged in via the power jack? Does it use the external power first? I was curious if it would be possible to make a solar panel to power the RCX when there is (...) (26 years ago, 9-Nov-98, to lugnet.robotics)
