Power Supply

Ensure your Lenovo PC is properly connected to a power source. Check the power cable and adapter for any damage. If possible, try using a different power outlet.

External Devices

Disconnect all external devices such as USB drives, external hard drives, printers, and other peripherals. Sometimes, these devices can cause conflicts leading to a black screen.

Monitor Connection

  2. Turn it back on and immediately start pressing the F8 key repeatedly.
  3. Select Safe Mode from the Advanced Boot Options menu using the arrow keys and press Enter.

What to Do in Safe Mode
  • Update Display Drivers: Go to Device Manager, find your display adapter, right-click, and select Update Driver.
  • Uninstall Problematic Software: If the black screen appeared after installing new software, uninstall it in Safe Mode.
