touch pad lagging Lenovo Z50-70

[hamidmughal8323]

It's been few days that Whenever I use my Lenovo Z50-70 while plugged in charging my touchpad starts lagging and causes delays to my work...?
kindly suggest if I should check for any hardware issue or internal settings.

recently I did a new windows 10 to it and couldn't find the right drivers for touchpad so it was idle for about a month(was using external mouse) now my brother had run a driver pack in it and the issue was resolved...

Driver pack? Did that driver pack come from Lenovo or a third party app? Also make sure you're on the latest BIOS update of your laptop. All necessary drivers can be found here.

Did you recreate the installer for Windows 10 using Windows Media Creation Tools?
