When I first got this Powerbook (G4 15" 1.6Ghz DLSD "Hi res") the first thing I noticed when it was charging the battery was the "feel" of the case. While resting my palms on the two spots either side of the track pad for instance, I can feel the case is electrified, it's only a tiny background charge but it's definitely there, most likely a charge. When the adapter was plugged in if I ran my hand over any bare metal part it feels "alive" (only way I describe it).
It's at its worse when the lid is shut and the computer is either in sleep mode or turned off. If I run my fingers over the lid my fingers literally feel like they're buzzing. If I happen to be using the laptop with bare skin touching the edges (like my stomach, since admittedly I tend to use the thing a lot in bed) I often get sharp stabbing pains, like someone is sticking me with a needle in the area where my skin is touching the case, though this only seems to happen intermittently and only on areas of my body with very sensitive skin, like my forearms on my stomach.
Thinking it could be a fault with the adapter I eventually got a new one (not because of this issue but because the original one got broken). And it does the same thing. It didn't do this at all however when the power adapter wasn't plugged in and it was only running off the battery.
This can't be right... I will mention that I've had two batteries for this laptop the time I've owned it and neither of them lasted much more than a year before they packed up. The first one started to discharge randomly after only a few months of use and got worse and worse until I eventually got round to replacing it a few years back with another original Apple battery shortly before they stopped making them. But the second one only worked for a year before it stopped charging completely.
Maybe it's related to the batteries. Maybe not. Either way, it just doesn't feel right...
