Touchpad not detected

[Ansh Shrivastava]

The touchpad of my Lenovo laptop stopped working suddenly possibly after an update. Apparently it seems that the touchpad isn't even recognised by the operating system yet external mouse works perfectly fine. I tried updating the kernel but it didn't fix the problem.
