I turned on mouse settings in BIOS from basic to advanced and when I turned my laptop back on, the mouse settings were set to default (pointer speed 6 and mouse acceleration on). I went to the control panel mouse see what happened but it was still set to my settings. I changed it and saved it but nothing happened. So far this is what I've done to try to fix it:
Turn the mouse settings back to basic from advanced
Rollback the mouse driver
Uninstall the mouse driver
But it still isn't fixed.
