Wednesday Search Challenge (Feb 2, 2011): How do I replace the little blue light on my ThinkPad?

Here's a real problem that happened just last week... 

A Thinkpad T400 developed a problem with the little blue light that comes on when you hit FN+home.  (That keyboard shortcut turns on a light to illuminate your keyboard.)

Obviously, I don't want to have you actually tell me how to replace the light, but if you can find the web document that tells me how to replace it, that would be perfect. 


Search on!
