So at some point this summer I lost the charger cord for my '06 macbook and have only just recently bought a new one for it. Needless to say my mac has just been sitting around the house turned off waiting to get a charge back in it. When I plugged the new power cord back into the computer and it started up (for the first time in weeks) there was a black "X" inside the battery icon in the upper right corner of the screen. Sure enough as soon as I unplugged the power cord from the computer it went dead. I immediately consulted Apple's support website and tried every solution that they suggested to fix the battery (Update the OS, update the battery itself, resetting the PMU, etc...) with still no results. This forum is my last alternative before having to call up AppleCare. Has anyone else had this problem and more importantly, does anyone know how to fix it?
