  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.
