I have a problem, the laptop only works with an external monitor.
The display does not work, the touchscreen works.
I tried rebooting the laptop, disconnecting the battery, updating the BIOS.

Earlier there was such a problem and it decided that the laptop was discharged and then turned on correctly. Now it does not help.

    With a cold boot and the monitor NOT plugged in, do you get an ACER logo screen on its LCD? Jack E/NJ

    Try to press the Fn key and tap the E key, this would switches the display output between the display screen, external monitor (if connected) or both.
    The Fn + R key would turn the Turns off the LCD back light. 
    Check if the brightness of the screen is down to 0

    You may also connect the external monitor, then reinstall the display adapter driver.
    If still no display on internal screen, it could be an internal cable connectivity issue or the screen.

    If the issue persists, you may contact Acer support in your region and send in the device for warranty service.

    If I turn on the laptop without a LCD, then NOTHING will turn on.
    If I turn on the laptop with a LCD, then the monitor lights up the Acer logo and i can enter the BIOS.

    Does your keyboard look like the image below. If it does, try pressing the FN+E keys to turn the LCD screen on. If not, please post and image of your keyboard and try pressing the FN+F5 keys to turn the LCD screen on. Jack E/NJ

    It is also possible that the screen is switched only to the external monitor! Press the windows + p keys and select "computer screen only"!

    If this does not work, there may be a problem with the ribbon cable or the monitor itself! When you put a flashlight next to the monitor, can you see the windows desktop?

    There is no a Windows problem. The Windows didnt know about "second" LCD.
    Possible ribbon cable :(

    Probably if the LCD is not detected. Part # 50.L7FN1.010 . Or google "sw5-271" "video cable" with the quotes. Not expensive but accessing it will likely be a challenge. Jack E/NJ
