  Duane ReedAug 18, 2025
  If your Lenovo Desktop computer system doesn't start normally, ensure the power cord is securely plugged into the back of the computer and a functioning power socket. Also, make sure any new or modified hardware is correctly connected. If you've changed hardware, you might see a configuration error message; press F1 to enter the BIOS, save the settings, and exit. Finally, ensure the computer is within its operating temperature range and has been at a normal temperature for at least 2 hours if it was moved from a significantly different outdoor environment.

  If your Lenovo Desktop mouse isn't working, plug the mouse cable into the correct mouse connector at the back of the computer after turning it off.

Ensure the desktop and mouse pad are flat and clean.

  If you experience discontinuous audio or video when playing a VCD/CD on your Lenovo Desktop, the CD may be of poor quality, making it difficult for the computer to read. Try replacing the CD.
