Latitude e6420 mouse cursor jittery
I have a Dell latitude e4620. I installed a new SSD and new windows 10 pro 64bit. I have every thing installed on device manager. The touchpad is jittery and jerky and doesn't give a smooth mouse pointer performance.
I've plugged in a normal USB mouse and it works fine.
I've gone into the bios and the mouse cursor works well in there so it needs to be something with windows.
I've installed various drivers from the Dell site, 2011, 2013 and 14. For the touchpad and same thing, restarting each time I installed them.
I've tried turning off gestures (and restarting) I've tired turning off touch guard I've tried increasing and decreasing the pointer sensitivity too as well as the touch pressure. Sometimes it acts like i have 2 fingers on the touchpad and might zoom that window.
I've cleaned the touchpad with some alcohol too.
At a loss of what else I can try, ideas?

I've figured it out that it only happens when the laptop is plugged in. It's not the original charger and it is a cheap one from ebay. But this is the problem.
I've looked through the power saving settings and can't see anything that'd change the mouse.
I think I'll need to set all power saving settings to the same as "plugged in" as it is "on battery" or the best one there is but I'll have to do some testing.

Your model is not approved or supported for Windows 10 so you don't have any Dell drivers for win 10. You have to depend on Microsoft generic drivers and some features of windows 10 will not work. Try updating the video driver in Device Manager. Let Windows search for a better driver. It doesn't make sense to me but video and mouse are closely connected. https://www.dell.com/support/home/us/en/04/product-support/product/latitude-e6420/drivers
Reinstall the Dell customized touchpad driver for Windows 8 and see it that makes a difference. Do not install any other drivers since you need Dell customized drivers even it they are for a diff OS.
Another option is to go back to your previous OS or buy a new laptop-- my preference. :Wink:
