Re: G50-80 - Laptop touchpad doesn't work properly while charging ?

Hi there, Nmparamar –


Thank you for writing in to the Lenovo Forum - happy to have you here today.


Make sure you use the original 65W 20V/3.25A or 90W 20V4.5A AC adapter that came with the unit.


Plug the AC adapter in another wall outlet in your house (preferably another side of the house) - if this works, the original wall outlet that you used before when you got the issue may not be properly grounded.


Perform a power drain by: a turning the PC OFF. Remove the battery & AC adapter then hold the power button for 30secs. When done, reinsert the AC adapter and battery then boot into the BIOS by pressing F2. When inside the BIOS, press F9 to reset default settings and press F10 to save and exit.


Update the Touchpad Driver below:

Synaptics Touchpad Driver       Synaptics Touchpad Driver

Windows 10 32bit / 64bit            Windows 8 32bit / 64bit


Update us how it goes.
