    Lenovo Ideapad 3 NM-C821 - no display after fall

    Hello.
    Have this Lenovo Ideapad 3 NM-C821 that suffer fall from meter flatly, and after that have no display. I cannot check another lcd because lcd is glued to back and i dont have spare lcd cable. All voltages are OK.
    No video on HDMI and no activity on USB, only voltage. What can be bad?

    i was thinking about cracked ball under RAM or CPU

    or how to check video when have no display?

                  Cracked ball under bga chip is unlikley as lenovo uses glue beneath it. Problem may be elsewhere.

                      Hi Guys,

                      CPU - i7-1165G7

                      However, if I attach an external display it works fine.

                      Observations: When I shut down the laptop from windows,
                      the fan remains spinning until I close the lid. If I leave the lid open
                      the laptop will restart on it's own although I select shut down from windows.
                      Also, when I check the voltage on the...
