No, you can only do that (change drive letter) from inside the program, or Windows.
Curious: beside the comic relief, when you reinstalled the battery but did not plug in the power supply you said the laptop would not power on at all. Do you think that battery is dead (not charging)?
Try removing the battery and just using the power supply. Although I can't think of why that would change anything, I've been surprised before!
