So, I have this Macbook 2008. The charger and battery are from 2006. I have noticed that when I put the machine to sleep, unplug the power cord for long enough time for the battery to get drained some and then plug the charger back it very often does not start to charge even though it should. After plugging the charger on and off it might suddenly start charging but very often not. The charging led is often totally off even though the charger is supplying power and sometimes, like at this moment for example, it is green even though the computer says battery is being charged. To get this original 60W charger to charge, I have now noticed that if I first plug chinese 85W charger it starts to charge right away and led works ok, after unplugging it and trying with the original charger it also starts to charge and led will lit altough not work correctly always. Is the original charger not being able to provide enough power or what?
