MacBook Does Not Turn On.

I recently got a new mac book air 2015 and it originally did not power on, not only did it not power on but it also showed no lights when plugged in.

I opened but the back of it and unplugged the battery from the logic board. The only thing this did was made the light on the charger turn back on.

I then reset the SMC and PRAM and plugged the battery back in

When I reset the SMC the charging light cycled from orange to green like it typically would

After doing all of these the device still doesn’t turn on.

However when I press the power button the fan begins to spin and I can feel the heat pipe getting warmer but, the charging light doesn’t cycle and there is no chime.

I feel like there is a post code issue that is occurring but I don’t know what it would be

Any help would be appreciated.
