I am using dell inspiron 15R 5537. I am having problems with my dell touchpad. I am using wireless mouse for a long time and just few days ago my touchpad stopped working. I downloaded the latest driver from dell website the touchpad started working back again. But again next day it just disappeared. And now its not even showing in device manager. I have tried everything to get my touchpad back. I have done diagnost to check the hardware problem but touchpad passed the test. If someone has any solution kindly posy it here.
