Mouse will wander across the screen on my laptop regardless if wireless mouse is on or off.

"or with touch pad"!!!

This suggests to me that you are using a Mouse.....with the Touch-pad still 'activated' when you're using the Mouse. On a lap-top/note-book.

Don't. This is what is causing the mouse's errattic behaviour.

Disable the "Touch-pad", via the Device Manager......whenever you're using the Mouse, and this erratic behavour should stop.

Enable it, again.................for those times when you use the lap-top/note-book in a 'mobile sitiuation'.

Hi jeff,

You might check to see if an updated BIOS firmware and chipset drivers are available from the laptop manufacturer.

You can also perform a clean boot to see if a startup program is causing a conflict:

Hi, Jeff, the only other suggestion I can offer, is,....................that in you REMOVING the TOUCH-PAD, from the Device Manager program, the MOMENT you turned OFF your computer (ala lap-top!)........the OS (operating system) REINSTALLED the Touch-pad (w/driver) back into the Device Manager program.

It will, therefore, continue to create HAVOC.....with the EXTERNAL Mouse that you (and, others) will try to keep on using. As it (the OS) will always REINSTALL what has been REMOVED if it (whatever the part is) has never been removed altogether from any computer.

You HAVE to.........DISABLE the Touch-Pad, within the Device Manager program. (Do not try uninstalling it! as it will jsut keep interfering with the EXTERNAL Mouse.)

Then, use the Device Manager program......................to SET either one up, for use, according to the SITUATION you are in.

The 'Touch-pad'....for whenever you are mobile, moving around!

The Mouse.............when you're at house or somewhere you will be for quite some time!

You either ENABLE, or DISABLE, according to the given situation!

Hey, as long as I have into computers, laptops/notebooks are not my 'thing', okay.

But, I do know that SOME mouse (external ones) do work OK with laptops WHILE others do! I can't tell you off-hand which one do or don't....thats up to you to find out. If you go for a 'cheapie'!, yes, you are asking for trouble.....they work all right for a desk-top computer but not so for any laptop.

Basic controls/basic actions, get it.

Touch-pads are more complicated, so, the external mouse HAS to be, also.

Common-sense, the understanding of my last line..........you should be able to fix your laptop's mouse problem in no time flat.
