I was excited to get this macbook. its in perfect condition. The day I got it, I charged it up and everything was going great. Then, the charger quit working. To the sellers credit, they sent me a new one. This was awesome, but then the computer was also overheating. I charged the computer to full and timed how long it would take the battery to go to 0. it took less than 4 hours. I notified the seller who used the excuse that the low battery life is due to it being a refurbished model. This was a very poor excuse and a lie. No where in the description does it say that the battery life would be less because its a refurb. On the contrary, its says the battery life should be an average of 10 hours and says nothing else. Refurb means that it should be like new with the possible exception of cosmetic. So what the seller is saying is a lie.
