Word of caution, and I may be a little paranoid here, but make sure the polarity of the substitute power supply matches that of the missing classmate supply. Off the top of my head I don't recall what the classmates is, but you should be able to see on the casing of the IBM what it is, or worst case take a DMM to it and check.

Just the other day I forgot to check this and put reverse power in to my USB/Serial Port hub and blew the power regulator in to two pieces. Oops. (This is why I own a soldering iron though...)
