However, would it really help? I imagine most interviewers would just say, no, put your computer away and grab this marker.
It's ultimately the interviewer's choice how to run the interview. We can try to nudge it and we can walk away, but it's ultimately up to them.
But if you didn't even try to solve the problem, don't come whining to me (on the internet).
That said, I would also recommend just dodging all these other technical problems. Maybe spend 30 seconds trying to get the projector going, but if it goes beyond that, just say "Let's just look at the screen here on my laptop". Unless you've being interviewed by more than 3 people, it can be managed. Come equipped with a full battery. Etc. But this is all manageable stuff... I manage to get this right for trips to the airport, surely one can manage for a job interview.
