Hi, Sounds like when you are typing your hand is hitting your touchpad.
My lenovo is a ideapad Y510 and I can go to start and type in mouse, open it from there then pick
Device Settings, from there you can disable synaptics touchpad, that should stop your pointer
from moving why your typing.
Make sure you have a usb mouse also so you can turn it back on when you are done.
