Steps
Plug the laptop into its charger and leave it for at least 30 minutes. A completely drained battery can look like a dead screen even when the power light blinks.
Hold the power button down for 20 seconds, release it, then press it once to start again. This clears a stuck sleep or hibernate state.
Shine a torch at an angle onto the screen while the laptop is on. If you can faintly see the desktop, the backlight has failed rather than the whole display.
Press the brightness up key a few times. On most Lenovo laptops that is F12 or Fn plus F12, and a screen dimmed to zero looks black.
Connect an external monitor with an HDMI cable and press the display switch key, usually F7 or Fn plus F7. A picture on the monitor means the laptop is running and the built-in panel or cable is the problem.
Power off, unplug the charger, and remove the battery if your model has a removable one. Then hold the power button for 30 seconds to drain leftover charge.
If you are comfortable opening the case, unplug the power first and touch a bare metal surface to discharge static. Reseat the RAM stick and check the display cable is firmly connected.
Start the laptop and tap F1 or F2 repeatedly to open the BIOS. If the BIOS appears, the hardware works and the fault is in Windows or the graphics driver.
Boot into Safe Mode from the Windows recovery menu, then update or roll back the graphics driver in Device Manager under Display adapters.
If the screen stays black in BIOS and with an external monitor, stop troubleshooting and contact Lenovo support or a repair shop. The panel or motherboard may need replacing.
Tips and common mistakes
Do not open the case on a laptop still under warranty, as it can void the coverage.
A faint image under a torch almost always means the backlight or its fuse, not the whole screen.
Test with the charger connected before anything else, since many black screens are just a drained battery.
Write down what you tried and when, so a technician can rule out simple causes quickly.
Questions
Why is my Lenovo screen black but the power light on?
The laptop is getting power but not sending a picture. Common causes are a stuck sleep state, a failed backlight, loose RAM, or a crashed graphics driver. Work through the power drain and external monitor tests to narrow it down.
What is the Novo button on a Lenovo laptop?
It is a tiny pinhole button, usually next to the power port or on the side, that opens a recovery menu. Press it with a paperclip while the laptop is off to reach BIOS setup, boot options or system recovery.
Will I lose my files fixing a black screen?
No, these steps do not touch your storage. Only a factory reset or reinstall erases data, so avoid those options until you have backed up the drive from another computer.
