I bought a MacBook Pro mid-2012 non-retina from the previous owner.
Some parts of my MacBook like the top-left most area of the touch pad will get me electric shocks when I touch it.
At my living room downstairs, it kind of makes we want to drop my macbook. If feels like someone flicks my finger.
At my room upstairs, it feels like being bitten by an ant or something small with sharp appendages.
What do you guys do to prevent this?
A friend suggests buying original power adapter but I'm unsure how to verify if my current adapter is original.
