My macbook pro charger stopped working sometime ago. In the meanwhile I have been using friend's charger without any problem.
Today I bought a second hand charger and when I tried to connect it with my Macbook, the charging light on charger blinked for few seconds and then stopped working. The Macbook Pro also stopped working and it doesn't turn ON, no matter how long I press the restart button.
The Macbook was 60% charged before I connected this new charger. So I am assuming the reason it stopped working is because I connected this new charger.
Any ideas, what could be happening?
