Did you let the system charge the battery up? What does the onboard battery checker tell you? What is the color of the MagSafe charger LED Amber or Green? [image|2361834] Did you do anything else like take the logic board out so you could clean the dust out? Did you use a small brush to scrub things down and then use vacuum or did you use a can of can’ed air to blow the debris out? You did something else here which messed you up. The swap out of the battery shouldn’t have don’t anything.
