A solution to the computer not passing the Post screen is to disconnect the pc from the electric power and to remove the battery for a few seconds. After reinserting the power and/or the battery my acer 5930G passes the post screen and boots.
I do not remember if this has already been written in one of the posts above and, if not, where I learned that.
