Hi @harsha8398,

Welcome to the HP Forums!

Thank you for posting your query in this forum, it's a great place to find answers.

I reviewed your post and I understand that the display goes off when you swipe two fingers on the touchpad.

Don’t worry, I assure you I will try my best to get this sorted.

In order that I may provide you with an accurate solution, I will need a few more details.

• When was the last time the computer was working fine?
• Have you made any software or hardware changes on the computer?
• Have you performed any troubleshooting steps before posting?

Meanwhile, I recommend you update the bios, chipset driver and graphics driver from the below link and test.
