I recently purchased an IBM ThinkPad R50e (1842-SUU) and can't figure out how to eject the DVD drive. On previous ThinkPads (a ThinkPad R40 - 2681-CU1) I could eject it by pulling a lever, of sorts, which would subsequently make another lever pop out. After pulling this lever, the drive would pop out. For the ThinkPad R50e, the initial lever is there, but nothing happens after pulling on it - no second lever pops out and neither does the drive.
Any ideas?
I ask because I have a lithium ion battery with the same from factor as the dvd drives that I'd like to be able to use in place of the drive from time to time. Unfortunately, I can't, as yet, really do this.
