What do you instinctively?

Situation: Projector does not like input from a Mac. 80 people coming in about 5 minutes and then it has to Work!. Called technician (coming in only 45 seconds!) begins to fumble around on the Mac and mumbles "well I'm not a Mac user really ...". By the wall is a PC - without power cord.

Question: Which of these do you choose:
1. Hope the best you've learned in 4 minutes then playing the victim-role?
2. Beg the technician temporarily stop fumbling and instead just put power to the PC which presumably are more likely to work with the Projector but in any case doubles the chance of getting the problem resolved?

If you instinctively choose 2) you have the right helicopter pilot genes.

2) is obviously the most difficult to implement, because the technician will feel:

a) it is a waste of time because the problem will been solved in about 2 minutes (or maybe 3 ...)
b) you interfering in something you have no sense of
c) you do not show respect for the technician's professionalism

You can either ignore  this and insist or if there is time ask if it is ultimately safer when 80 people are now dependent on a solution right now?

This little situation you can transfer again and again at the specialists you are surrounded by.
