He will not fix it so that you get a "particular" lab, he will fix it so that you get into a section that does not conflict with the rest of your courses. It may or may not be at a time that is convenient for you, but nobody really cares whether or not you WANT to wake up at 8:30 on Monday, or stay until 5:00 on Friday. However, in many cases you have the option of switching the lab OR the thing it conflicts with, and he may ask you to try that first.
Usually there are a decent number of people doing this, so if the sections that work with your schedule legitimately are all full, he'll then look at switching the sections of the people with conflicts (ie, take one person out of one full section, thus creating a spot for you, and then putting that person in another section that works for them).
