Did you have an update to the system and did it say it had to update the firmware or something like that? If so, I would allow it to finish the booting up, until its completed the firmware update, any interruption to the firmware update might lead the laptop to be bricked
I had a similar thing. Kind of worrying when you see that, considering I've been with one manufacturer for the best part of 20 years and that's not happened once with them
