Pavilion G6 : power supply plug in with reversed polarity . I was trying to help a friend with their laptop. The power supply for it was not a HP supply but an after market supply. Tarus universal power supply.
I was moving the laptop and the plug going into adapter the laptop came out, however the plug into the adapter was 180 out of phase. In other word plus+ was minus- and minus- was plus+. Now the computer will not turn on what have I blown in the computer.
