Thanks Dwayne,

I use a very old USB powered intellimouse, it's a 5 button gaming mouse=20
(manufactured in 1998), and based on the battery life in the laptop=20
computer, my guess is that it pulls a hefty current. It does have 2=20
leds, one to power the scanning and another that is just a pilot lamp.=20
Led technology wasn't good in those days, so it's likely the reason for=20
the power sucking LED's.

 From your description of the shaking you have to do to wake up both=20
your units, it sounds like both of your mice have vibration sensors=20
built into them already. I suppose I could get used to shaking the mouse=20
to start it up, but a nice sensitive vibration sensor is what I'd prefer=20
to have.

I have been looking at very cheap low end units, maybe that's why I=20
found they had power switches in them!

Thanks so much for the info.

ur mice already have vibration sensors to
