Hi
@Khaleesi3 , the seats in the lecture hall do not all have outlets for every seat. There are seats on the side that do have some available. If you end up being a lecture goer the most lectures we have ever had in a row is around four hours but more typical is 3. I have not heard from any of my classmates that battery life has ever been an issue. I have to imagine the students that have a computer that would potentially putter out sit on the edge but more likely they have it charged and ready to go for the lectures. Also, of the 170 students maybe only 20-30 go on a regular basis so there is no competition for the plugs.
Michigan has no laptop requirements in terms of type. There are some general specifications that they ask you to have so you can do histology, watch videos, etc. Nothing onerous. People use regular PCs, MACs, ipads, and Microsoft Surfaces for their note taking. A few students print out the coursepack as well. During Launch (orientation) there will definitely be a session dedicated to technology to get you all squared away before classes start.
Hope that answered your questions. If you have any more please feel free to reach out at anytime.
