MacBook Air will not power on (Battery replaced)

Was my everyday computer. Tried to boot it up when I got to school; no power. When connected to power, no charging light. I thought this problem was the battery, so I ordered one on here and replaced it (correctly). Still no power or charge light.

I did a little experimenting, so I tried charging the computer with the battery disconnected. Powered up until the apple logo appeared, then turned off for good. Now, charge light appears amber, but computer will not power on (Battery connected). Must be logic board?

Any help is immensely appreciated.
