The computer powers on and I can hear the (very loud) chime when Windows is done loading but there’s no video on the built in display even after replacing the LCD assembly (it appeared to include the backlight board with the panel). It is usually used with an external monitor as the previous panel wasn’t working either. PC laptops are a little outside my knowledge, but I am very well-versed in Apple repairs. In Apple terms I want to reset the SMC (system management controller) but I don’t know how to do that on a Thinkpad. Does anyone know or have additional ideas? (I have tried the Microsoft troubleshooting steps for no video and they did not resolve the issue.)
Thanks!
