Dell 5480 - touchpad not smooth move on battery


Recommended Posts

Hello again.


Until now, I have been working on a laptop connected to the charger non-stop. And everythinks work well. But now when i unplug power adapter from laptop i notice that my touchpad didn't work smooth. The cursor jumps differently on the screen, you cannot operate the touchpad smoothly. When i connect adapter to laptop cursor move smoothly.


On external mouse everythink works well.


Does anyone know what the problem could be?


I attach debug files. All kext are updated.


Best regards.
