MacBook won't charge after speaker replacement

Hi I used your guide to replace the speaker but now it won't turn on

The first run after reconnecting everything the speakers worked perfectly I had to reset date and time but it didn't recognize the battery it appeared with an x on the display

So I reopened I it to check if every thing was plugged in correctly

It was but when I connected the charger the light(green or orange) on the charger wouldn't lit and now I can't get the computer to start ,to turn on

Any advice????
