How to fix the mouse drifting on Windows 10 on a Toshiba Portege Z30-A

I have been struggling with this problem on and off for years (3 years of ownership) and have fixed this in the past by updating drivers, changing ports, etc. It seems that the problem is fixed and then someday, the same thing happens all over again!

In summary, it seems that the problem is related to the accupoint device (that blue dot in the middle of the keyboard). The way the problem seems to be fixed now is by disabling it all together. How? Follow the instructions below:



How?
Double click the touchpad icon on your system tray. (the one with the red cross)

Then, unmark the Use AccuPoint. Please note that if you tap the left top corner of your touch pad you can turn the Touch Pad on and off. and when you turn it on after unmarking the Use Accupoint, it can also turn the AccuPoint back on! So, go ahead, and see the Use Accupoint turn on and then select it off again. After that turning the touchpad on and off will not affect the AccuPoint. (or at least until it happens again and they you will need to repeat this procedure. Good Luck!
