No green power light means the board is fried, or the USB port is disabled.  USB ports will shut down if overloaded, but generally reset like a fuse if you power cycle the computer.

What happens if you try a power adapter or a battery?  Center of the jack is positive.

Servos draw quite a lot of current, so that may have damaged something, either in the USB port or the Arduino.  Can you use the same USB port to power other USB devices?

It doesn't sound like anything was damaged. Try powering the servo from an external power supply. Don't forget to connect the Power supply ground to the Arduino Gnd.
