@Kirubeldan, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
I understand your HP laptop won’t turn on and a BIOS reset hasn’t helped. Let’s walk through a few steps to try and get your system back up and running.

Perform a Hard Reset

This helps drain residual electrical charge that might be preventing startup.

For laptops with a removable battery:

1. Turn off the laptop and disconnect all external devices.
2. Remove the battery and unplug the power adapter.
3. Press and hold the Power button for 15 seconds.
4. Reinsert the battery, plug in the adapter, and try turning it on.

For laptops with a non-removable battery:

1. Turn off the laptop and disconnect all peripherals.
2. Press and hold the Power button for 15 seconds.
3. Reconnect the power adapter and try powering it on.

Try a BIOS Recovery

If the screen remains black, try recovering the BIOS using a key combination:

1. Turn off the laptop.
2. Press and hold Windows + B (or Windows + V on some models), then press and hold the Power button for 2–3 seconds.
3. Release the Power button but continue holding Windows + B/V for another 10 seconds.
4. If successful, you should see the BIOS recovery screen.

Check External Display Behavior

Since you mentioned connecting to a monitor:

• Disconnect the external monitor.
• Try powering on the laptop standalone.
• If it turns on, the issue may be with display settings or the external monitor itself.

Test with Minimal Configuration

• Remove all USB devices, SD cards, and external drives.
• Try booting with just the power adapter connected.

If none of the above steps work, the issue could be hardware-related (e.g., motherboard, power circuit, or display). In that case, please visit the nearest HP authorized service center, the service team will check and assist you.

Take care and have a good day.
