Sometimes electrical components needs to have all power sources removed and reintroduced to work properly. Try performing a hard reset first, if it doesn't work then we'll move to the next step.
To Perform A Hard Reset
- Shut down the computer by going to the Start menu and selecting shut down. (If you have no display, hold the power button down for 5 seconds); (if the computer doesn't power on, move to the next step)
- Disconnect the AC Adapter from the notebook.
- Remove the battery from the bottom of the notebook. There will be a switch/button to eject the battery.
- Wait at least 1 minute with all power sources disconnected.
- Re-insert the battery and reconnect the AC Adapter and then attempt to power on the notebook.

I tried this and it didn't work.. many times. Is there another solution please?
I would recommend updating your HP System BIOS to the latest version.
You can check the current version by opening the System Information utility via the Start Menu --> under System Summary check the BIOS Version/Date then see if there's a newer version available on the HP Software & Drivers page for your notebook.

Uninstall and reinstall battery drivers
1. Press Windows key + X and click on Device Manager.
2. Expand Batteries and right click on Batteries ACPI and click on uninstall.
3. Restart your laptop and see if the issue persists.
This is the last software troubleshooting step we can try. After this, you would need to try a new battery and/or power adapter to see if one of those parts are the problem. Most likely, it's the battery.
