Anyone? Please.

What were you doing when it stopped working?

Were there any updates done at the time or before it quit working?

I was watching NBA. As I am from Europe, time difference is huge so I fell asleep during a game. When I woke up laptop was in rest mode. Then I shut down the laptop, after few hours I turned it on, and touchpad wasn't working. Nothing changed since then. If i remember correctly, there was update before it quit working.

My touchpad came defective from the manufacturer. It will be replaced and if that doesn't work, I'll need to replace the notebook.  Things I tried and didn't work for me, but may work for you:

-Update the driver

- Update Windows  10 and all HP pending updates

- Update BIOS

- change sensitivity of touchpad

Good luck

Will try it. Thanks.

After I updated BIOS, touchpad started working again. I hope it'll stay like that. Thank you for help. Cheers!
