I dont think you can get somebody to touch that one for $100. Who did you buy it from? Do you have an option to return it as defective?
The locking up is a serious issue. I have two XE7s and I pray they never do that because I will have to junk them. Too expensive to repair and a bitch to repair to begin with, from what I am told.
I would try my damnedest to get that refunded. You might also contact Jon Goodman who may be able to help you out, maybe not. I think Craig Held might have some insight or ability also.
Here is Craig's profile for contact info:

Good luck.
