Hello KeyaRob,
Welcome to the HP Forums! I hope you enjoy your experience!
I understand the computer's touchpad is not working, and will not turn on. I will do what I can to assist you! To troubleshoot the issue, please try the steps in this HP document: Using and Troubleshooting the TouchPad or ClickPad (Windows 8)
This document will show you how to turn on and use the touchpad. I believe it will help you out. Either way, please provide the results.
Thanks for choosing the HP Forums. Have a great day!
Mario
