since 2 days my laptop (type 4240-CTO) don't show anything when booting. The keyboard also doesn't respond and speakers are nonfuntional.
But if i plug in an external monitor, an usb-keyboard and headphone everything works as expected.
I recognize an short flickering on the lcd display shortly after booting, but then its dead. With the external monitor the boot-process is fully visible.
Has anyone some hints for me what to do?

I looked a bit around within the forum and found this thread: https://forums.lenovo.com/t5/ThinkPad-T400-T500-and-newer-T/T520-Keyboard-and-Display-failure/m-p/20...
I guess it describes the same problem i have.
