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

[nmparmar]

I bought a Lenovo G50-80 (intel(R) Core i3-5005U, 2GHz) a few months ago. A week after buying, I noticed touchpad not working properly while charger plugged in, also it was not working while my printer’s USB cable connected. Touchpad button and finger tap working fine but, cursor hanging or moves very slow. When I unplugged the charger and printer cable touchpad working fine. But, it was not working anymore (it is also not working properly when the charger and printer’s USB cable unplugged). Usb mouse working perfect.
My Laptop have installed windows 7 64bit operating system. I tried to reinstall windows 7 64bit ultimate and professional os (Not other like windows 8 or 10), I updated a latest bios and touchpad driver from Lenovo and synaptics website, But I am getting same problem.

Hi there, Nmparmar          -

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

Can you try to:

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 (preferrably 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      

Update us how it goes.

There are no nearby lenovo service centre.

Hi,

Go to Device Manager, expand the Human Interface Devices, right click HID compliant wireless radio control and disable it, I have already disabled it hence it's showing enable in my snip. Let us know if it helps.
