Summary
This article guides you through troubleshooting a laptop that refuses to power on, wake up from sleep, or show anything on the screen.
Symptoms
- Pressing the power button does nothing.
- The screen remains black, but the keyboard or power lights turn on.
- The laptop beeps or the fans spin, but the screen stays blank.
Before You Start
- Access to the laptop's original power adapter.
Instructions
Stop here if a drink was spilled on it. A hard reset is the wrong first move after a spill — powering the board on while it is still damp is what causes the permanent damage. Follow What to Do If You Spill Liquid on Your Laptop instead, then come back to this guide once the laptop has dried for 24 to 48 hours.
1. Perform a hard reset
- Disconnect all external devices, including monitors, mice, keyboards, and USB hubs.
- Press and hold the power button for 30 seconds to drain residual power from the motherboard.
- Release the button, wait 5 seconds, and press it once to turn the laptop back on.
If no light comes on and the fans stay silent when you press the power button, the laptop is not drawing power, and where that power comes from is the next thing to check. Continue to Step 2.
2. Verify the power source
- Plug the laptop directly into a wall outlet, bypassing any power strips or docking stations.
- Check if the laptop's charging indicator light turns on.
- Wait 15 minutes to let a completely dead battery charge before attempting to turn the laptop on again.
If lights or fan noise return but the screen stays black, the laptop is powering on and the display is the problem. Continue to Step 3. If the charging light stays off after 15 minutes on a wall outlet you know works, the adapter or the charging port has failed. Raise a ticket giving the laptop's model number from the label underneath it, the fact that no charging light appears on a known-good outlet, and what the laptop does when you press the power button.
3. Check for external monitor issues (Windows only)
- Check if the keyboard lights up or you hear fans spinning.
- Press the Windows key + Ctrl + Shift + B. This restarts the graphics driver and can fix a black screen.
If the keyboard is lit and the fans are running but the screen stays black after that shortcut, the display or the graphics hardware needs a physical repair. Raise a ticket saying the laptop powers on with lights and fan noise, the screen stays black through both a hard reset and a graphics-driver restart, and whether the manufacturer's logo ever appears at power-on.
Troubleshooting
WARNING
If your laptop has a swollen battery (the bottom looks bulging, the laptop wobbles on a flat surface, or the trackpad is popping out), stop using it immediately and unplug it. This is a fire hazard.
| Symptom / Error | Potential Cause | Solution |
|---|---|---|
| Black screen with loud beeping noises | Hardware failure (RAM or Motherboard) | This requires a physical repair. Submit an IT support ticket. |
| Laptop turns on but immediately shuts off | Overheating or completely dead battery | Ensure the vents are clear and it is plugged in directly to the wall outlet. |
