I have a new MBP early 2011 model. I get no more than 2 hours of battery life no matter what I do. The MBP has two upgrades: 1. HDD replace with an Hitachi TravelStar 5K750 2. RAM upgraded to 8GB with 1067 DDR3 I've turned off blue tooth, unloaded unnecessary services, tried it with and without WiFi on. Nothing is working. I've charged the battery fully, then drained it completely, then recharged. Still nothing. I get just 2 hours. The HDD replacement uses LESS wattage then the drive that was in there. I'm just not sure about the extra memory. This is driving me nuts. I travel a lot and spend 4+ hours in a plane most of the time, so good battery life is a must for me. At least with my older MBP I had spare batteries and I could change them out during the flight. I bought this new MBP to eliminate the need to carry those extra batteries. Has anyone seen this before? Or, have a solution?
