I purchased a broken MacBook (Santa Rosa) from Ebay several month ago. I use it as a media center connected to my home theater. The MacBook was dropped and had a broken screen and a beat up case. It was always the eye sore of my entertainment center. I recently decided to put it in a custom tiny enclosure witch is nothing more than an attractive external hard drive case. I got it all together and everything is running great...except one tiny detail. The MacBook underclocks itself to 1200 MHz when the battery is not connected. After much research I discovered this was intentional by Apple and all advice given to me was just put the battery back. I don't have room to put the battery back I just have it laying next to the computer causing the same eye sore I had before. There has to be a way to "trick" the computer in thinking the battery is connected. I wouldn't mind it if 1200 MHz was enough raw power to decode HD h.264 but its not. Does anyone know a way to either directly attach the mag safe adapter directly to the battery terminals or somehow short the pins to simulate a connected battery? Or better yet a software solution?
