Use the drivers from the HP 250 G4.

HP 250 G4 Notebook PC Software and Driver Downloads | HP® Support

Do not install the latest BIOS on the support page as that is only for the 250 G4.

If there is a reason you want or need to update the BIOS, use F.29:

I need recovery bios for 15 notebook ac-650-tu.

Bios recovery driver.

Using the F.29 BIOS file link I posted, you make a BIOS recovery drive.

Watch these videos for how to create and use a BIOS recovery flash drive with the above exe file using another Windows PC:

I did the same. It reinstalled /updated bios.

Process took around 15-20 min. 

After that it restart laptop and again nothing appears on screen and  earlier caps blink 2 times. Now no caps blink.

What to do?

There's nothing you can do.

If that process didn't work it's time for a new notebook.
