“The computer is turning on but the monitor isn’t. When I press the small button in the back it says input signal is not detected. Does anyone know a fix??”

• The button in back of the Lenovo IdeaCentre A540 27 All-In-One System, model number F0EK007HUS, activates the HDMI-In port for connecting an external video source to your computer, using the IdeaCentre A540 27 AIO screen for external video input from a video source, like a game console. It sounds like your computer is looking for the new video signal, but there is none. Try pushing the button one more time. Then restart your computer. Your computer should now boot normally, displaying the Windows Login Screen. If the issue continues, we recommend you contact Lenovo Tech Support for additional help at: 877-453-6686.
