    The problem is the subject. Lenovo G50-30 has a damaged matrix, that's why it was connected to the external monitor via D-SUB. After making and saving changes to the BIOS, it stopped displaying the image on the monitor. F10 without results.
    Please provide a hint on how you can restore the factory BIOS settings without access to the interface. Maybe there is a jumper or battery on the motherboard?

    I located the battery. Unfortunately, it is soldered permanently. Anyone know a way to reset the BIOS other than by removing the battery?

    Approx. When connected via HDMI, I could get an image on an external monitor, so I could enter the BIOS and reset the settings. Subject to close, thank you.
