This text is not important but it is somewhat entertaining.
The Brazilian server Fórum PCs has an interesting article that describes an omnipresent laptop keyboard timebomb of Hewlett-Packard notebooks (English translation). The punch line of the article is a "magic URL" to a very efficient guide written by Prof. Schwinger of Harvard University that tells you what is the reason of the problem and how to fix it.
The Brazilian computer enthusiast includes two photographs in his article. Both of them are exactly identical and both of them show that Prof. Schwinger has exactly the same model of a notebook, knife, scissors, and digital camera as your humble correspondent. ;-) The Brazilian source reveals that Julian Schwinger offers a better computer support than HP itself even 12 years after his death.
