hmm wish i saw this reply before now.. i thought it would have emailed me oops
anyways, i talked to ISTNC and they directed me to asus support...
i called them at 510-739-3777 and they told me i needed part number 13-N988AM150
they also directed me to extension x5116 to order the part. the lady at that extension verified that the part was the one i wanted and directed me to the estore

$20 shipped to me.. now just hopefully ill be able to replace it. not too bad of a price. if it doesnt work out for some reason ill look into the other free parts. thanks for the info thought!
