Hi DinaAllison1,
Thank you for reaching out Microsoft Community. We apologize for the inconvenience this may have caused you.
Just want to clarify, are you referring to a Bluetooth or wired mouse connected to your Surface device or you're referring the trackpad or the touchpad on the keyboard?
Once the mouse is acting erratically, possible reason could be due to the mouse is not clean, the optical portion of the mouse is blocked, it's being placed on a bad surface, bad wireless connection or it has a failing batteries and there's a moisture or
a liquid substance on finger while using the touchpad.
Whatever mouse you are using, you can follow the steps below to fix erratic mouse issue,
Clean Boot to fix erratic mouse issue :
I actually read an online article about it and figured out that performing a clean boot for your computer reduces conflicts related to software that can bring up the root causes of the erratic mouse issue. These conflicts can
be caused by applications and services that start up and run in the background whenever you start Windows normally. In order to successfully perform a clean boot on Windows 10, you have to be logged on as the administrator, then follow these steps:
Solution 1 :
- Go to the search box
- Type msconfig
- Select System Configuration
- Find Services tab
- Select Hide all Microsoft services box
- Click Disable all
- Go to Startup tab
- Open Task Manager
- Close Task Manager then click Ok
- Reboot your device.
Solution 2: Use System settings to turn Mouse Acceleration on and off
Follow these steps to fix the erratic mouse issue using Mouse Acceleration:
- Right click Start
- Select Control Panel
- Go to Hardware and Sound
- Select Mouse
- Choose Pointer Options tab
- Uncheck Enhance pointer precision box to turn off Mouse Acceleration
- Click Apply then click Ok
- Check if the mouse works properly now
If not, proceed with Solution 3:
- Right click Start
- Select Control Panel
- Go to Hardware and Sound
- Select Mouse
- Select Click to change Touchpad settings
- Click Sensitivity
- Check the Turn On box next to Touch Guard
- Move the white circle under Touch Guard to your extreme right (towards the + sign)
- Click Save and close touchpad utility
- Click Ok
If in case it is still moving erratically, you can uninstall/reinstall the driver of the mouse.
- Open Device Manager
- Expand Mouse and Other Pointing Device
- Right-click on the available mouse drivers and select "uninstall device" and uninstall it successfully. Then,
restart your Surface to reinstall the drivers.
