I bought a new laptop HP pavillion x360 14m-dw0023dx after three months of use the laptop didn't power up, I tried every manual possible solution, know that when i contact the power cable the led indicator indicates that the laptop is charging, and after so many attempts my lap top power up but a dim screen almost black screen which i noticed it by luck appears and i so hp logo and windows 10 start normally but without any control of mouse and keyboard i pressed the caps lock  button to see the led indicator but nothing happened and the backlit also wasn't working and after 15 min the screen appears clearly and i had a full control over my laptop, but when my laptop sleeps or shut down the laptop dies and i have to try to open it over hundred times

From your description, it certainly sounds like a hardware issue.

Software failures will generate on-screen messages, usually about not finding an Operating System or not being able to boot. When the screen is blank, the PC is experiencing a major hardware failure.
--------------------
To determine the cause with hardware failures, you have to be able run diagnostics. We have no way of accessing your PC from here, so we can not do that for you. You have to do it yourself.

You do this by pressing the Esc key repeatedly when rebooting and then, when the HP Startup Menu appears, selecting Diagnostics (usually F2) and letting it run.

If it is NOT possible to run diagnostics, or if that does not work, then there is NOTHING more you can do by yourself -- and there is NOTHING we can do because we have no way of accessing your PC from here to run diagnostics or repair hardware.

You will need to have the PC physically examined in a service facility by folks that can run their own diagnostics to determine what is wrong with it.


Since your PC is no longer under warranty, then it will cost you up front to have HP examine your PC. If you want to do that, you will have to contact an HP Repair or Service Center to see if they can examine the PC to determine the cause(s) of the problems, if it can be repaired, and an estimate of the repair costs.

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

If you don't get useful results using the Service Center link, here is the main HP link:

If you can't get assistance from HP, then you will have to seek out a local laptop service facility to have them examine it for you.

Good Luck
