After poweron I got a black screen (led not on) but other hardware working(fan ,caps lock light, power light).

Caps lock light is static and white.

I have dual booted os, windows 10 with Ubuntu.

@Amit2468 Welcome to HP Community!

I must let you know that we don't support nor recommend dual boot, please try booting with windows OEM version and check if it works after you remove the Ubuntu from the device,

If the issue continues to occur on the factory shipped OS as well, please try the below steps:

• check if it works fine on an alternate/external monitor.
  • If it works fine on an alternate screen, please Perform a hard reset, Attempt a BIOS recovery  and then, Run the System Diagnostics tests.
