OK, I see: the charge isn't being drained, it's being equalized. If this is the case and is what avoids a damaging discharge, then I guess the computer wouldn't need to be plugged-in. Well...that's why I said "Could be." :=) If so, then perhaps it wouldn't be affective to use any other method (like plumbing) for grounding except contacting the computer metal itself because the charge wouldn't be equalized.
