Polarity on power tips
The power tip on my netbook had become very temperamental. SO I took it apart. I did not not polarity of the tip. Is polarity standradised or does it vary from manufacturer to manufacturer?
The netbook I have is MSI U100 series. I do not want to end up with reversed polarity.

It's usually the central one, but this is not universally adopted; you need to check it.
