fujitsu notebooks
Why Fujitsu Notebook computer has leakage AC~17Volts through the exposed metal part when connected to wall AC?
Whenever I used my subject notebook computer, I can feel the biting sensation whenever my skin touches the exposed part where current is leaking from such as metal nuts, casing edges etc. Thus, I measured those little parts with my multimeter which showed ~17V AC live on those points. It is quite painful if exposed to the skin.
That is NOT a good sign! You have a Grounding issue some were, you need to take the laptop in & have a service tech look at it before it shorts out completely! This can & will lead to a MAJOR failure!
