# Laptop Screen Black but Power On

## Quick Answer

If the laptop has power indicators on but the screen is black, the issue could be display-related, a graphics driver crash, or a sleep mode problem.

Please note:  This guide is provided for informational purposes only. Any steps you choose to follow are at your own discretion and risk. If you're unsure, we recommend booking a professional diagnosis.

## Quick Checks

Try these fast checks first — they solve most cases.

1.  Press a key or move the mouse
    
    The laptop may be in sleep mode.
    
2.  Increase brightness
    
    The brightness may have been turned down to minimum.
    
3.  Connect an external monitor
    
    This determines if the issue is the screen or the graphics.
    
4.  Force restart
    
    Hold the power button for 10 seconds and restart.
    
5.  Check for keyboard shortcuts
    
    Some laptops have a display toggle key (e.g., Fn + F7).
    

## Guided Troubleshooting

Answer these questions to narrow down the issue.

Does an external monitor show output?

YesNo

Can you hear the laptop running (fans, hard drive)?

YesNo

## Possible Causes

Sleep mode or hibernation

Very Common 

The laptop is in sleep mode and not waking properly.

Brightness at minimum

Common 

Brightness accidentally set to zero.

Graphics driver crash

Common 

The GPU driver has crashed.

Display cable loose

Moderate 

The cable connecting the screen may be loose.

Backlight failure

Moderate 

The screen backlight has failed.

If the cause requires professional attention, see [Get Laptop cracked screen fixed](/repair/laptop/cracked-screen).

## Self-Fix Instructions

Safe steps you can try at home.

1.  ### Display troubleshooting
    
    1\. Press keys and move the mouse to wake from sleep. 2. Press brightness up key multiple times. 3. Try the display toggle shortcut (Fn + F-key). 4. Force restart. 5. If still black, connect an external monitor to diagnose.
    

## Safety Warnings

-   If you can faintly see content under bright light, the backlight has failed and needs professional repair. 

## When troubleshooting isn't enough

If these steps didn't resolve the issue, a professional diagnosis can identify the root cause.
