SZ75 palmrest electric shock - i thought they had fixed this by now?!

I had a SZ23 that gave me a wild electric shock. I know that this was a standing issue with older SZs that was fixable with a 3 pronged power plug.

Recently i got a SZ75. Not only does it have a crappy LCD (worse bleeding and veiwing angles than my first SZ), but like the SZ23, it gives me a electric shock through the palmrest. When i put the back of my hands on the palmrest whilst on AC power, i feel tingly + my fingers twitch a bit. I also hear slight sparking sounds (like ZAP ZAP ZAP ZAP ZAP repeatedly). It doesn't hurt, but its very uncomfortable and disconcerting.

Now, my adapters has the 3 pronged australian plug; what is happening and how do i fix this?

 

plug your metal sided toaster into the same plug...see if you can feel the same effects...seriously....could be the recepticle is wired incorrectly....what mains voltage do you guys have down there?

 

i've tried different plugs :s




at any rate....why would i feel shock through my palmrest anyway? is it somehwo connected to the laptop's powerplay?


THe voltage in australia is 240V i think

 

Did your try different plugs in a different building?

It's possible the laptop may not be grounded properly (The 3rd prong being the ground wire). This could indicate some sort of wiring problem with the ground wire either within the building, the plugs or somewhere else (speculation: the power brick).

^regarding voltage. This doesn't make a difference since laptop power supplies can handle any input voltage around the world. You just need the correct prongs.

So if you plug your laptop into another power outlet in another building and you still feel the same electric shock then the problem is probably your power brick. If not then it could be the wiring in the current plugs you're using.

Or maybe you have an electric personality?

 

is your palmrest made of aluminium (or some other alloy)? i've experienced this with other electrical objects which have proper metal cases. In particular I get a slight tingle when i touch the surface of my technics hi-fi...i have noticed it seems to happen on high-end goods, my friends Teac system has the same tingly feeling to the touch!!

if yours is really so uncomfortable though then perhaps it is more of a power issue. Have you tried brushing your finger over the rest in complete darkness? Any sparks?
