While those diagnostics may well demostrate that a problem exists, the lack of a problme is not demonstrated by a machine passing all diagnostics. In particular, on a previous Dell i5000e laptop, it was not until 8 days before the warranty expired that I discovered conclusive evidence that the (DB-9M) serial port did not work at all. This, despite passing Dell's diagnostics with flying colors. And this was because the diagnostics -- from what I can guess -- did not attempt to actually transmit or receive data via the serial port. So: by all means, use the diagnostics, but use a suitably-sized "grain of salt" in evaluating the results. Peace, david -- David H.
