Mouse turns off randomly

i have a microsoft usb intellimouse and it just randomly turns off, when it turns off the only way to get it back on is to restart my computer. dont say anything about ps/2 ports cause im on a laptop that only has usb's. and i went into my device manager and turned "turn this usb off to save power" off. i need help fast, i can barley use a mouse pad

^ +1. I would also borrow/try another mouse & see if the same problem occurs. If it does, try deleting & then reinstalling the USB drivers, and also download & install the Intellimouse app off MS's support site.

Odd, I was just having the exact same problems with the same mouse on my laptop starting a few days ago...I don't think mine is as bad as yours is but the symptoms are the same, I'll try some things and if I figure it out I'll let ya know...honestly though I just figured the mouse was dying and I wasn't too upset about it seeing as it has been under heavy use for nearly 8 years. So not sure but if I were to guess anything I'd just say get a new mouse, I probably will get the exact same one I have now due to reliability.

frey, its not my mouse, its my usb ports, like i said on my post, ive tried 3 different mouse

what kind of computer... what OS do you have more than one mouse.. a built in trackpad or something? what models were the mice you tried it with.. what brand.. do you have the mouse software installed? Is it wireless or corded

I worked on a laptop where the trackpad wouldn't respond, when connected to power.
As soon as you unplugged the adapter it would work.

Have you tried using a PS/2 mouse?

Strange, I've got a logitech Mx518 USB mouse under windows Vista 64-bit that has begun behaving similarly over the last few days. Now that I think about it, there was a windows update that automatically installed only a day or two before I noticed this behavior... wonder what that update was...

Anyway, when it turns off I just unplug it from the usb port, wait for the computer to see the device gone and then plug it back in to get going again... at least until the next time it stops!

I too just thought my mouse was dying until I came across this thread...

I have the same problem with a newly installed WinXP and a Trackball in an industrial Sigle Board Computer...!, first I've disabled the option in the Device manager-> Root USB...>Energy Management..> the situation happens less often but it happens... and I can't find any solution for this.

I have this situation in 4 computers, they 4 have the same configuration in WinXP and in the BIOS.

No idea what is happening

Intellipoint mouses are notorious for developing shorts in the wire. The damage is done during the manufacturing process, when the top half of the mouse is pressed together with the bottom the wire is pinched. In time, it will short out.

Buy a new mouse.
