Hi - Hoping someone can help me with this. I am trying to test out an old late-2006 MBP. It's the 15" and so uses the 85w power supply. Unfortunately, I don't have one available. I don't want to buy one if the machine is no good. I DO have access to a 60w magsafe power supply, though. Here's what I know: 1) The unit will power on fine with the 60w PSU 2) The battery shows up in the system profiler. It's completely discharged, has only 83 cycles, and gives a condition of "Check Battery" 3) The unit will NOT charge the battery wether it's powered up or shut down. The magsafe connector stays green, and the charge indicator in OSX indicates "Not Charging" What I need to know: 1) Should a 60w power supply charge the battery, albeit slowler than the 85w, at least when the computer is powered down? 2) If it should, but it's not, and computer powers on, does that indicate bad battery or a bad charger board (the PSU is known good)? 3) Would a completely discharged battery trigger the "Check Battery" status in System Profiler? Any other input on this? Thanks!
