Lenovo Y50 touch screen, ghost touches

Today my lenovo started randomly showing as if someone were tapping the bottom of my screen and pinching. It reoccurs frequently, is extremely annoying, and causes general chaos. How can i fix this? Ive tried updating display drivers and touchpad drivers. Please HELP!!!

Re: Lenovo Y50 touch screen, ghost touches

Hi Cesarr25 , 


Welcome to the Community Forums.


Would you have the machine number ? Check on the machine number from the sticker or check it from here ,just keep your serial number confidential.


Would the issue be the same even if you disable the touch screen feature?


Initially try power drain by turning off the laptop , removing the ac charger and battery (if removable) and press and hold down the power button for 12 seconds. 

Place back the battery and turn on using the Novo button to access the BIOS setup and on the exit tab , load defaults then save and exit. 


On the device manager , show all hidden device and uninstall HID-compliant touch screen and restart . Test further by turning on and use the novo button to power on the laptop. Choose system recovery and see if display show the same issue , just restart after testing.


Update us how things go.
