My wife dropped her Karma today and is on the verge of tears. I haven't looked at it yet so I really can't give details, but she says it simply isn't coming up. It's about 5 days out of warranty (just my luck), but she doesn't know where the receipt is anyway. Is there something I can do to get this fixed? She wants me to open it up and take a look, but is there any real point? Is there anything potentially wrong that I could fix myself?

Any help would be greatly appreciated. She is totally hooked on this now and the thought of living without it is already unbearable.
