touchpad stopped working completely and does not show up in devices

[Paul Bloom]

At first the touchpad was working. But, it recently stopped working entirely on this laptop. When I ran cat /proc/bus/input/devices I did not see any touchpad devices.

Status changed to 'Confirmed' because the bug affects multiple users.

Touchpad was working fine, until it just decided today morning to stop working. Upon checking the devices, it doesn't show up in the list of devices detected.

My laptop woke up from suspended mode, and I tried restarting the machine to check if it solves the issue, but no luck.

Touchpad was working all fine until recently, it stopped working altogether. And now /proc/bus/input/devices does not show touchpad. It just shows 2 input devices as Finger and Pen which could be of a fingerprint and touchpen as my laptop is touchscreen.

Attaching the devices list. Don't know what to do. This is a dual boot laptop and it also has started happening in my Windows OS as well.
