I have a Toshiba Tecra M2 laptop and an erratic mouse. I have the same problem with both a wireless mouse and a usb corded mouse. They work fine but after about 30 minutes the mouse becomes unresponsive and/or erratic.

Any thoughts?

Thanks much,

John

Get a Thinkpad with ultranav and you don't need a mouse anymore. <g>
Once you've used the trackpoint you'll never go back!

You didn't say, but I assume they are USB. Does the problem occur if you connect them via a different port?

It is doubtful that both mice have failed in the same way, but if you have another corded one, give it a try as well.

I suspect interference or problems with the built-in touchpad. If so, there might be a driver problem, or the touchpad might be defective or need to be reconnected internally (I've seen internal connections come loose). As a test, try disabling the touchpad, first in Windows, then in the BIOS Setup (or equivelant). You might also be able to disable it via some sort of Toshiba utility or control, if one is provided. If disabling the touchpad causes the problem to go away, then try re-enabling it and updating the driver. If that doesn't help, then since I always suspect problems with malware or a corrupted Windows load, I'd install a spare HDD with a clean install of Windows and see if the problem still occurred.

If it happens even on a clean install, but only when the touchpad is enabled, even with the proper drivers installed, then it would seem to be a touchpad hardware problem. In that case you could either run it with the touchpad disabled all the time, try re-connecting it internally, or try replacing it. Let me know what you find, Scott.

Here is how the erratic mouse problem was fixed.

1. It is a Toshiba M5
2. Tried different mice at different USB ports - did not fix the problem.
3. Disabled the touch pad - did not fix the problem
4. Removed all mouse programs and registry entries per Microsoft KB 322756 - -did not fix the problem.
5. Installed another HDD with a known clean load - did not fix the problem.
6. Replaced keyboard and touchpad - did not fix the problem.
7. Replaced mobo - fixed problem!

Effectively, I burned down the barn to kill the mouse!

Thanks for your support and add this to your KB.

You did a great job troubleshooting that one, going through potential causes in a proper order (from most likely/least expensive to least likely/most expensive). Too bad it had to be the worst case situation (motherboard). Thanks for letting me know the outcome! Scott.
