Hi CarlosPassos,
I understand your Touchpad is not working on your Envy M6 K015dx computer. Here is a fix that has worked well for other customers.
Touch Pad
running windows 8..on home screen type "DEVICE MANAGER"
then select device manager..select Touchpad's driver from the list.
Right click on Touchpad's driver
select update driver
select 1st option, download it from internet
select it from list of installed drivers
manually search for drivers(second option)
from the list of drivers installed for Touchpad select the latest one
install it and restart your system.
Here is a link to the drivers for the Touchpad.

Please let me know how this goes.
Thanks
