My Aluminium chassi is electrified!
When I have my Macbook Pro connected to the charger, the chassi become electrified. I do not know how many volts och amperes there is, probably not many. But when you drag the fingers over the computer, you get a humming feeling in your fingers. When standing on a chair, the humming becomes less. If standing bare foot on the floor you feel it very clearly, and if you holding something that is earthed at the same time as you touch the computer, it will hum so much in the fingers, that it hurts.
How can I fix or repair this problem?

This is a known issue
use the grounded AC extension cord not the two prong "short" AC adaptor.

Well, it looks like you might have a problem with your charger then, because normally it will only put out something like 25V, and 2A. That shouldn't be powerful enough to give you a tingleing feeling in your fingers. You might want to make sure that the DC-in board is properlly grounded, and is not shorting out anywhere in the case.
Note: since I'm not completelly sure what model MBP you have i linked you to the part/guide of a 15" A1226. If you tell me the model number of the computer, i can find the right guide.
MacBook Pro 15" (Model A1226) Left I/O Board

It turns on and runs?
