We are using many L440 in our office.I face same problems with most of them.Touchpad floats on screen.It moves on it own.I am not able to find permanent solution for this.
In some i had replaced touchpad by claiming warranty..It works sometimes and sometimes not.I have updated bios, drivers but no luck
I followed guides which had same issues...Uninstallaing power managment driver than reboot and than reinstall..
i tried replacing charger but still
Please suggest me fix for them.
