Hi@Peter_WJ,

Welcome to the HP Support Community!

In the meantime, let's start off by performing a Hard reset on the Notebook:

Step 1: Performing a hard reset

Resetting the computer can resolve many issues that cause a blank screen. Use the steps in Performin...

Step 2: Connecting an external monitor to test the display

The notebook screen display might remain black when there is a corrupted graphics driver or a problem with the LCD display backlight. To test the display, attach an external monitor and restart the computer. Testing with an external display is helpful if the notebook display is black but you can hear sounds; such as fans, spinning drives, or beep tones that indicate the computer is operating.

Next thing, I would suggest here is to Run a System diagnostics test as well as an extensive test on the Hard drive and Memory from F2 (Please capture the failure ID for further assistance).

If all test pass turns off the computer.

As you turn it back on tap the F10 key. This will load the BIOS setup utility.
Press F9 to load defaults.
Press F10 to save and exit.
