I was going to mail my 2 board to him to do just that! Both worked but would not save time. One had save ghosted and one did not. Both had slightly leaking batts but nothing that you would think would cause damage: But they did do damage to the RTC area.
So you asked him to fix that and he didn't? On my 2 4000s with this problem, I ended up fixing one of them on my own with the tutorial that was posted by the previous poster. The 2nd one I have not had time to try to fix, but am hopeful I will be able to.
