keyboard – MacBook Pro does not start anymore, only Trackpad responds

I used my MacBook Pro (Late 2017) in the recent days, but suddenly it had an unexpected shutdown and the screen went dark. What I saw before the immediate shutdown was a notification, but I wasn’t able to read anymore since the shutdown occurred just a few milliseconds.

Well since then, I can’t start the MacBook anymore. I can press the button and I can feel, that the Trackpad is active, so it is „clickable“. But unfortunately there is no screen turning on or any component running else on the Mac.

Does anyone had something similar in the past or is there a keyboard shortcut to get to some recovery tools? I just wanted to ask before I go to a repair store since the warranty has expired.
