A laptop that powers on but shows only a black screen is alarming, but most causes are fixable at home. First work out which kind of black screen you have.
In this article
First: what exactly happens?
- No lights, no fan, nothing: a power problem. Start with “No power at all” below.
- Lights and fans come on, but the screen stays black: a display, memory or firmware problem. Start with the hard reset.
- The Windows logo appears, then it goes black (maybe with a mouse cursor): a Windows or graphics driver problem. Jump to “Black screen after the Windows logo”.
No power at all
- Try a different outlet, and check the charger’s light if it has one.
- Try another compatible charger. For USB-C laptops, try a different USB-C port.
- Leave it charging for 30 minutes. A fully drained battery may need time before the laptop will start.
- Do the hard reset below.
Step 1: Hard reset (fixes a surprising number of cases)
- Unplug the charger and all USB devices, docks and SD cards.
- Hold the power button for 30–60 seconds. This drains residual power and resets the hardware.
- Plug the charger back in (nothing else) and turn it on.
Some laptops have a pinhole battery reset button on the bottom (common on Lenovo, Acer and some Dell models). Press it with a paperclip for about 10 seconds, then try again.
Step 2: Check whether it’s just the screen
- Shine a flashlight at the screen at an angle. If you can faintly see an image, the backlight has failed (a hardware repair).
- Press the brightness-up key a few times. Brightness may simply be at zero.
- Connect an external monitor or TV via HDMI and press Win + P, then choose Duplicate. If you see an image there, the problem is the laptop’s screen or its cable.
- Listen for the Windows startup sound or caps lock key response. If the laptop responds, it’s booting and only the display is the problem.
Step 3: Reset the graphics driver
Press Win + Ctrl + Shift + B. You’ll hear a beep and the screen will flash as Windows restarts the graphics driver. This often fixes a black screen after waking from sleep.
Black screen after the Windows logo
- Press Ctrl + Alt + Del. If a menu appears, open Task Manager → Run new task, type
explorer.exeand press Enter. - Boot into Safe Mode: force the laptop off three times during the Windows logo to reach the recovery screen, then choose Troubleshoot → Advanced options → Startup Settings → Restart → 4 (Safe Mode).
- In Safe Mode, open Device Manager → Display adapters, and uninstall the graphics driver (or roll back a recent update in Settings → Windows Update → Update history → Uninstall updates). Restart.
- From the recovery screen you can also try Startup Repair or System Restore.
- As a last resort, reset Windows from the recovery screen.
Black screen with a cursor (after signing in)
If you can see and move the mouse pointer but nothing else appears, Windows is running but the desktop (Explorer) didn’t load.
- Press Ctrl + Shift + Esc to open Task Manager.
- Click Run new task, type
explorer.exe, and press Enter. The desktop should appear. - If it keeps happening, restart, then uninstall any recently installed app or update, and run
sfc /scannowin an admin Terminal. - Still happening? Boot into Safe Mode (force off three times during startup → Troubleshoot → Advanced options → Startup Settings → 4) and remove the culprit.
Laptop screen black but the external monitor works
- Press Win + P and choose Duplicate or Extend. The laptop may be set to “Second screen only”.
- Disconnect the external monitor and restart. The laptop screen should come back.
- If the laptop screen stays black but external monitors always work, it’s likely the laptop’s display panel or its cable. See our screen flickering guide for hardware signs.

Signs it’s a hardware problem
- Beeps or flashing lights in a pattern at startup are diagnostic codes. Search your model plus “beep codes” or “LED codes”. They often indicate a memory problem.
- Built-in diagnostics: Dell hold Fn while powering on (or F12 → Diagnostics); HP Esc → F2; Lenovo F10 or Lenovo Diagnostics.
- If the laptop recently had a spill or a drop, take it to a repair shop.
Prevent it next time
Keep Windows, graphics drivers and BIOS updated, avoid force-shutting down during updates, and keep a bootable Windows USB around for emergencies. Back up regularly so a hardware failure never costs you your files.
