Thank you for joining in @NagaNatarajan, 

I understand that you are having an issue with the keyboard and touchpad on your HP Notebook 15-ac027tx. I wanted to lend you a helping hand. 

Have you tried to use an external Keyboard and mouse at all?

Have you tried going into Safe Mode to see if the problems persist in there?

Have you tried Performing a Hard Reset or Forced Reset?

Have you done a hardware test?

Have you updated all of your drivers? 

Please try the follow troubleshooting steps for both the keyboard and touchpad:  

• Start
• Search for Device Manager
• Open Device Manager from the Search results.
• Click View
• Show Hidden Devices.
• Click the arrow next to Keyboards.
• Right-click the keyboard device name.
• Select Uninstall.
• Continue removing device names in the Keyboards category until all device names have been uninstalled.
• Restart the notebook twice. 

Touchpad:  

• Type in Search, "Device Manager", 
• Click On Device Manager,
• Expand Mice and other pointing devices,  
• Right Click on the TouchPad, 
• Click on Uninstall,
• Restart the Notebook twice, 
• Reinstall the TouchPad Adapter.

I found a troubleshooting document for you to try also called Notebook Keyboard Troubleshooting. Please make sure to follow the steps in this document. 

The best document I have for TouchPad issues is the Using and Troubleshooting the TouchPad or ClickPad document. 

Here is a link to the HP Support Assistant if you need it. Just download and run the application and it will help with the software and drivers that need updating.
