Windows 10: Laggy touchpad when my laptop is plugged in

When my laptop is not plugged the touchpad's completely normal but once I plug in, I feel like the touchpad gets a little bit laggy and when I ask other people if they notice it too and they all say it's the same, so I'm the only one who notices it and I assume it's because I'm constantly using it, plugged or not so I obviously feel the lag.What could be the matter?

I want to disable touchpad on Dell laptop


Hello everyone,
My laptop's touchpad works and I don't want it to, because I prefer a mouse. It's a Dell Inspiron 11 3000 series on windows 10 OS.

What I have tried that hasn't worked:

• start<settings<devices<mouse & touchpad<additional mouse options. This opens a window called Mouse Options which has 5 tabs up top, none of which involve the touchpad. The Hardware tab shows 2 devices: the mouse itself, and the USB. No touchpad there.
• windows key+x<mobility center. No touchpad to be found.
• various function keys. No options for touchpad on/off.
• device manager<mice and other pointing devices. Again, only the mouse and usb show up. It appears the touchpad is working without a driver, which is a little spooky.

Any other suggestions? I could try downloading a third party driver, but that seems like a step in the wrong direction.
Thanks

These 7 steps allowed me to disable my touchpad (Dell laptop, Windows 10):

1. Win Start button
2. Type in "device manager"
3. Select Device Manager to open it
4. Click down arrow to left of "Mice and other..." to expand
5. Right click Dell Touchpad
6. Disable device
7. Yes

 

TouchPad problem

see attached screenshot of the keys after I re ran the scan

so i assume next steps are to have that program open that you suggested whilst using the laptop and then when the touchpad gets disabled to check if the keys have changed?
