macbook doesnt turn on.

[geekme]

I plugged in a usb cord, my macbook pro switched off itself, it was then connected to the adapter.After that the adapter also gives dim green light( not the usual one, but dimmer).Since then macbook has not switched on.No light , no fan noise.Please help.Have tried ctrl+command+power button , but no help.
regards.

Try using a different power adapter and start up again. When you press the power button did you hear any sound or there is totally nothing not even a single word on the screen as well?

may be your power cord is not working properly, try other cords
