MBP 2012 13 - Won't turn on

[iTouchTheSky]

I just tried to replace my SuperDrive DVD with another HDD, but now my Mac Won't power up ... I tried putting back my SuperDrive back but no luck there... The powercord doesnt light up neither the battery status led...

Help me please

Just out of curiosity, did you reconnect the battery? Normally when I remove my optical drive or ram I disconnect the battery and forget to put the connector back. If not then you may have damaged the logic board (but this is rare).

Did you try resetting the SMC first?
Disconnect all power and press Power button for 5 seconds, then reconnect all power. If that doesn't work, connect magsafe and battery and press left Shift+Ctrl+Option+Power button at the same time.

The top method isn't how you reset the SMC on a computer with a non user serviceable battery.
