I've noticed that lately my power adaptor's powering indicator doesn't light up. I thought maybe my adaptor was going bad or the laptop was needing repair or something. Then today, I noticed the settings reading the following: So, the light was not lit up, the power source was the wall charger and the battery was not charging. My question is this; when did this start happening? I've had this MBP for a year now and never noticed this. Was this a software update? I've always wanted my battery to not charge when plugged in if it was already at 100%. Note: I'm running 10.6.7 Build 10J869, 2.26 GHz Intel Core 2 Duo, 4 GB 1067 MHz DDR3.
