True. I installed it without disconnecting the battery. Triggered the computer to wake up a few times during the install by opening the doors on accident and what not. As far as the AC, it seemed like the functions of the AC were acting weird. If i turned the fan on by pressing the up arrow multiple times it wouldnt turn on. The only way the fans would turn on is if i clicked the MAX AC button where it would turn on recirculation as well and the fans to the max, but still would not blow cold air. All was normal when i got rid of the jb4
