Black screen, but the keybord, powerbutton and facial recognition LED's are turned on...

[tsthijs]

When I try to switch my laptop on it shows a black screen, the powerbutton-LED is turned on. After a couple seconds the keyboard LED turn on too (Because I have that thingy turned on). And after a few more seconds the "Facial recognition LED's (those two red ones and the white for the camera) turn on like normally. If I put my face in front of it, they turn off again... So based on the LED's everythings seems to function normally... but, the screen is still black...

I tried putting my TV as an external divice by using an HDMI cable, but it doesn't give out a signal. (I even tried the windows shortcuts Windows+P, but it didn't work.)

I also tried turning it off completely and start the laptop while I press:

Windows + B

Windows + V

But also those two didn't help turning my screen on...

I run (one of) the latest version of Windows 10.

Yes my device was fully charged

I don't know if it is 32bit or 64bit, but I think 32bit.

Does anyone els have this problem too? and does anyone els have a solution?

@tsthijs Welcome to HP Community!

Here's what you need to do, to identify the issue and resolve it accordingly:

• If not done already, check if it works fine on the BIOS screen to identify if it's either a hardware or a software issue:
  • If it works fine on the BIOS (Accessed while tapping F10 during a restart) it's a software issue & I suggest creating a new user account to check if that works better, for starters)
  • However, if it doesn't work within the BIOS either, I'm afraid it's a hardware malfunction.

While you respond to that, I have a few more steps that should help: 

Perform a power reset (no data loss) using these steps: Click here, proceed to next step if this works

Attempt to run a test from the HP hardware diagnostic tool, using this link: Click here for details.

If the issue appears on the diagnostics, it could again, determine a hardware failure,

If they don't appear on bios & the hardware tests passed: please update the BIOS & Chip-set drivers from the HP website using this link: Click here

if the issue persists, reinstall windows using the recovery partition or the recovery media to fix the issue,
use this link for details on performing the recovery: Click here

Let me know how that pans out,
