I got a MPB mid 2009, and i went to clean it out and disconnected the battery(everything was fine before). But when i went to go turn it on, it wont. It shows a big x over the battery sign. What should i do? Ive tried resetting the SCM. But heres whats funny, when i went to go turn it on right as it showed the boot screen i disconnected the charger and its working but it still shows an X over the battery. Yes i'ved used the search button.
