White spots on screen

There’s sudden appearance of white  spots on screen

This is almost certainly an indication of failing video hardware -- either the screen or the video chip or both.

You need to connect an external monitor to the laptop.

If the visual artifacts also appear on the monitor, then it is a failing video chip and since those are soldered to the motherboard, they are not replaceable.

If the visual artifacts do NOT appear on the monitor, then it is a failing laptop screen. While those can be replaced, the cost varies enormously by individual PC model.

We are not able, or permitted, to provide any repair estimates or equipment prices.
For this information, you would need to contact an HP Repair or Service Center.

Since you live outside the U.S., here is a link to HP Service Centers, by Country/Region: https://support.hp.com/in-en/service-center

Good Luck

thank you so much for the response 

But if it’s an hardware issue then it’s covered under warranty,right?

We're not allowed to commit to warranty coverage.  I provided you info on HP centers.  You would have to contact the nearest one and see if they will support the work and repair under the warranty.  We have no say in that.
