Re: Lenovo G50-80 toucpad not working properly when the charger or Printer’s USB cable connected

My feeling is that the power supply is causing electrical interference. The touchpad is likely connected internally via USB, which CAN (won't always of course) be susceptible to interference

 

I can confirm that some issue disappears when they do the following: - unplug the power supply from the laptop. - Touch a metallic part of the laptop (i.e. USB port) - place the laptop on my lap (probably earthing it as above). - touch the power supply with the hand.

 

Update us how it goes.
