How long will it take for a MacBook charger to charge a lifeless MacBook pro? I have just attached it! Didn't switch on straight away! Thanks!!!
It will take a little while longer as the MacBook charger is 65 watts I think, and the Macbook Pro charger is 85 watts. Its okay to use the Macbook charger on a Macbook pro as a temporary basis, but you need to fully charge the Macbook Pros battery first (until the magsafe connector light goes from Red to Green), and then use it. If using the macbook pro with the macbook charger plugged in, you might notice the battery draining, due to the fact that the macbook pro uses more power than the regular macbook charger can provide. Hope this helps!
