X200 won't boot, won't power up correctly, screen blank, speakers click repeatedly
My X200 never successfully turns on.
When I press the power button, within about 3 seconds, the speakers (under the palm rest) start clicking. It's very regular: click (wait about 1/5 second) click (wait about 4/5 second) then the pattern repeats, continuously.
Meanwhile, the screen remains dark and blank. No sign of the backlight at all. And even if I shine a bright light on the screen, I can't see any sign of text, graphics, or anything else... the LCD is completely blank.
At first I had thought the clicking was the HD, so I even removed that. Then when I heard the clicking again, I realized it was the speakers. So I discovered that removing the HD does not affect the problem.
I swapped out the RAM from a known good machine... no change.
And there are no beeps... I don't think POST is running at all.
Has anyone else had this same set of symptoms?
Thanks in advance!
