  I always used the earthed cable and the problem still occured. I thought I had made a comment about this in CPH to you (maybe not, maybe to someone else). I never noticed the hum, but sure noticed the friction. Plus I think i had minor shocks when I had sweaty hands and wearing my bracelet (it had a hanging part that would occasionally touch the powerbook at that spot right next to the mousepad belw the spacebar). Good to know, after two years, that it's not me ;)

    Ah right. I was sure someone had mentioned it before, and tried to find a reference to it on use.perl. I think that acme mentioned it at some point too.

  So only do not one's family jools get bathed in radio frequencies but they will get gently electrocuted, too?

    Not if they're safely at the same potential as the rest of the case, I believe. I think that the only danger is if they're one's only point of contact with someone (or something) else that is earthed:

    "Did the earth move for you?"

    "No, but you caused some interesting tingling sensations."

  This is a an annoying problem for me, since I rest my arms on the frame when typing and it then hurts my arms.
  
  I am writing this on a fully charged battery and the sensation does not occur, so I think it only seems to happen when the machine is charging.
  
  A funny thing was, when the other day I could feel the current on my girlfriends back, when she was using my TiBook.

  This live chassis issue is very common, and very old. The description of the touch sensation as like a surface roughness is dead on, too! The problem stems from the fact that the actual power supply (in the mains adapter) is completely floating with respective to the earth ground. There is a very small capacitive coupling from both sides of the supply to the chassis, essentially making a voltage divider that places the chassis at half the mains voltage above ground. In the UK, that's roughly 120 volts AC, a
