Blank Screen

• I would turn on my laptop, sign in and then be welcomed with a blank screen, what could be the problem please. This is really heartbreaking

Hi @NonyeNuella,
 
Welcome to the HP Support Community!

Thanks for reaching out!

I Understand your concern about the display issue, don’t worry let me help you with this.

To better understand the issue, could you please provide a few more details?
 

• The exact HP laptop model you’re using ?
• Whether the screen is completely black or if you can see the mouse pointer or taskbar faintly.
• If you hear any sounds (like the fan running or Windows startup  sound) after signing in.

Here are a few quick  steps you can try right away:

1. Check display brightness – Sometimes the brightness is turned all the way down. Try adjusting it using the brightness keys.
2. Restart with Safe Mode – Hold down the power button to force a shutdown, then restart and press F8 or Shift + F8 to see if you can boot into Safe Mode.
3. External monitor test – Connect your laptop to an external display (TV or monitor) to check if the issue is with the built-in screen.
4. Hard reset – Disconnect all peripherals, unplug the power adapter, and hold the power button for about 15 seconds. Then reconnect and power on.

I hope this helps.

Hello @Deep_World

Thanks for your reply 

My laptop model is HP Elite book 840 G3

I have tried all the 4 options you gave but none worked 

It still gives a black screen 

I can only see the mouse pointer and nothing else

I don't hear the fan running but sometimes, I hear the Hp start-up sound, some other time I don't
