Download the instructions from www.USCIS.gov. Page 8 states that only the "following categories" are NOT required to pay the fee when renewing the EAD: (a)(8), (a)(10), (c)(1), (c)(4), (c)(7), (c)(0) or (c)(16) (applied after 7/30/07).

You should retain an attorney to review all the facts specific to your case in order to receive advise specific to your case. The statement above does not create an attorney/client relationship. Answers on Avvo can only be general ones, as specific answers would require knowledge of all the facts. As such, they may or may not apply to the question.
Most likely you will have to retake the biometrics again (fingerprints) hence the $80 fee in addition to the EAD renewal fees. As the other colleagues pointed out go to www.uscis.gov, click on forms on the top, then scroll down to I-765 and there you can check the fees and also the instructions. By the way administratively closed is nice BUT it means the government did you a favor and temporarily backed of, they administratively closed the case without prejudice but in the future they can re-start the process if they so choose, i.e. the Court retains jurisdiction on your case not USCIS. Good luck.
