Logitech X-240 off button?

[protokiller]

I bought these things today for $40 and for the most part am happy with them but I can't find an off button...

I'm one of those people who likes to save energy for my family every way I can but I don't want to have to unplug them every night.

Does anybody know of a secret way to turn it off and also whats your opinions on this speaker system?

The button that lights up is the on/off switch

It was driving me nuts! I was about to take it apart, had started to look around for where the fuse was when I found your comment, ibebofa! I thought a power spike had knocked them out. Thank you.
