Shawn LH; I got the exact same problem! The power jack is soldered with alot of silver I guess, cause it needed a very high temp. 450C was just enough, and the extreme small space did not help much.. I replaced the jack but the DC jack area on the motherboard had suffered alot of heat, so it did not connect anymore. Now ASUS can't support me and they refuse to send me a new motherboard.. have anyone tried bying boards on ebay?
