If its indicator light is blinking, reboot/restart (maybe several times) till it quits blinking. Then push the regular eject button.

Or you can try shutting down the puder-- turning it off. As it goes thru shutdown, if the blinking stops before power is gone, push the button right then and it may eject. Pop in a fresh CD if you can and close it, or put in the fresh one during startup.

The question is, is it stuck mechanically... or is it not being recognized by the software properly and blinking because it thinks it's an elephant in a refrigerator?
