So today I got my Led Zep Premium...my first NIB game and my first Stern.

Like the rest of my games, it's plugged into a wall outlet that is attached to a wall switch. So when I'm done with the gameroom for the night, I just hit the wall switch and leave.

Tonight, as I did that, I looked back and saw that somehow my LZ stayed on.
Okay, so I guess modern Stern games have some sort of a battery back-up? If that's the case, is there any reason why I should be concerned about leaving the pinball on and allowing it to sit there running off the battery backup until it depletes?

For memory. Not to remain on.

Your wall switch isn't turning that outlet off.

Obviously it feels you weren't done playing it!

I think iirc they take a bit to boot and they must use big or super caps to help, but they stay on a few seconds after the power is cut.

How long did the game stay on?

Also most outlets that are switched. Usually only one plug of the two are actually switched. Have you verified that is the case?

If you only have 1 pinball plugged into each switched outlet you are probably be ok but it wouldn’t hurt to check to make sure the switch isn’t connected via the spring loaded push clamp connector thingy. Can you tell I don’t know the technical name? Rather it’s better to use the screw mounts on the switch. Not sure your age of house tho either. (This isn’t addressing your issue brought up but if you have several games on one switch it’s best not to use those spring connectors)

Yeah if you turned off your switch for just a second you may still have some residual power for maybe 3 seconds. If your switch is off for more than 5 or 6 and the game is on…you got the wrong outlet.

Switching power supplies, such as in Stern games, take a big current surge at turn-on, because there is a large filter capacitor directly at mains input (behind a rectifier of course). This surge can cause wall switch contacts to weld together and stay closed.

Most often this occurs with remote controlled sockets, but I would not be surprised if it happens with a wall switch also.
