Macbook Won T Turn On Battery Is Not Charging Macbook Pro 13 Unibody Early 2011

Chosen Solution

My battery is not charging. I have tried unplug the battery connector and tried to boot using magsafe power but it wont turn on. The power indicator is lighten and then blinking 3 times, so do the fan, it spinning and off continously.

What does the battery indicator LED’s telling you? On the front side you’ll find the battery checker press the button

Does the LED’s light up? Do all of them or only a few? Do they stay on or do they blink?
