MacBookPro does not power up on AC power or battery
MacBookPro does not power up on AC power or battery after it has been on before. I have to unplug the battery and the power adapter and then wait a couple mins, then plug in AC adapter and unit power ups and loads OS with out issues. I then can plug in (new one just bought) battery and it sees, charges, and runs off battery. Once the unit is powered off, it will not respond with the battery plugged in and or AC adapter left plugged in. The green light on the charger remains on when powered off and I've tried 3 known good adapters.
