I spent a while one day searching on the web for definitive documentation stating that unquestionably you run the risk of destroying your entire mainboard and/or the PS/2 if you hotplug. I couldn't find any. As far as I know the PS/2 devices are supplied power through the port, so I guess it seems logical that hotplugging could be a risk, but other than conjecture and various anecdotal evidence, I have come up blank on the risks. Can anyone on the list point me to a manufacturers site or documentation that unequivocally states in clear terms the real dangers of hotplugging a PS/2 device? Like some of the other people who have replied, in the past I have hot-plugged many a PS/2 device to no detriment. However, I now only do it if there is no other practical alternative just to be on the safe side.
