Display is not getting ON

Hi @Arunkumarn,

Welcome to the HP Support Community. 

I'd be glad to help you! 

• Do you see any backlight on the screen, or is it completely black when you turn on the laptop?
• Have you tried connecting your laptop to an external monitor to check if the issue is with the laptop display or the system itself?
• Did you notice any unusual behavior or error messages before the screen stopped working, such as a system crash or update issue?

CAUTION : If your computer does not turn on, wait at least 5 minutes before troubleshooting the computer. Your computer might be installing an update for Windows or the BIOS or detecting new hardware. During this update process, you can expect the screen to be blank for several minutes. It might damage the computer if this process is interrupted. Do not turn off or unplug the computer during the update process.

Perform a hard reset

If your computer suddenly fails to boot properly, perform a hard reset (power reset).

For detailed instructions on resetting your computer, see HP PCs - How to power reset your computer.

•  
• Turn off the computer.
• Disconnect the AC adapter.
• Remove any discs from the disc drive.
• Remove memory cards from the card reader slot.
• Disconnect all nonessential peripheral devices, such as printers, scanners, external hard drives, and USB flash drives.
• With the AC adapter unplugged, press and hold the power button for approximately 15 seconds.
• Reconnect the AC adapter, and then turn on the computer.

Note:

If an error message is displayed, see HP PCs - Resolving diagnostic errors that are displayed during startup.

Otherwise, continue with the troubleshooting procedures in this document.
