I've called Apple and they couldn't find a solution for me.

It took about 15 minutes just for that person to start dealing with me because they need to check if I'm still on AppleCare and it took the person 15 minutes to do so. Not bad enuff, the person speaking to me on the phone actually made me gone through again, all the steps I've already done (I've made a search online in the Apple Support website ealier before calling and done all the steps mentioned there) earlier on. The person put me on hold almost about 6-8 times and I had to wait for him to go and find information and run me down the steps which I already knew! I got so frustrated up to a point where I said, hey I've been through all you've said, is there A SOLUTION for this on call or should I just bring it to the STORE and he put me on hold, well again and finally came up with this Reset Power Management which I had already done earlier on as well. I told him that and he said that he'll have to speak to the iBook specialist whatsoever and at that point, I got extremely frustrated and I decided to just hung up the damn phone!
P/S: Anyone know what i need to bring if I'm going to bring in my iBook to the store? I don't think I still have the box of the AppleCare but I do have my iBook Enrollment Number with the CD and UserGuide. What do I need to bring along to prove that I have AppleCare and any recomendations on what to bring? I had registered AppleCare obviously since the person can detect that I'm on protection. Thanks in advance.
