A customer of mine gave me this board in hopes of finding out if a previous shop really needed to replace her MB. I have found some posts on the web stating similar problems with this brand. The problem is the Keyboard. The Keyboard lights do not flash at boot up. There is no sign of the keyboard during POST. The board does not identify the missing keyboard when the keyboard is unplugged. Now.. the strange thing is that the Keyboard controller passes the POST test. It seems to me, the only thing left is that there is no communication or voltage going to and from the keyboard socket to the keyboard controller. Has anyone ever contacted Biostar about this issue? Have they given an explanation? The Keylock has been checked along with almost ALL other possibilities.
