i shut down my MacBook mid 2009, next time I went to use it nothing, totally dead, thought it might be a flat battery, connected the charger, the light glowed dimly green, but nothing like normal, left it for a few hours, still nothing, tried disconnecting the battery even with that disconnected could only get the dim light still dead, did get it booted once but even with the charger disconnected, it said no battery present. Charger is fine as have connected it to another MacBook. Any ideas, as I'm stumped, surely if it's a battery problem it should boot from charger with battery disconnected.
