Hi @Victus23,

Welcome to the HP Support Community. 

I'd be happy to help you! 

Was the laptop charged when this happened?

Meanwhile, try the following:

POWER DRAIN:

Please disconnect all the devices and cables connected to your computer including the power cable and then press and hold the power button for about 20 seconds and connect the power cable back again and try to power on the computer.

CBR:

Press windows key and then follow by the key "B" this time and then the power button for around 3-4 seconds, then release the power button and continue to hold windows+B for 3-4 seconds more.

BIOS default:(do not skip any troubleshooting steps even if you feel steps are repeating)

1. Turn off the computer and wait five seconds.
2. Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu.
3. On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
4. Press F10 to Save and    Exit.
5. Use the arrow keys to select Yes, then press Enter when asked to Exit Saving Changes.
6. Follow the prompts to restart your computer.

If this does not work, then the unit might need service.

Hope this helps! Keep me posted for further assistance.
