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.

The motherboard will have been damaged by reversed polarity. New motherboard required.

Thanks for your reply.

I guess I was lucky, I tried the laptop the next day and it worked just fine.
Still done not know why it would not boot before.

I'm suprised how many people, when scrounging around for an adapter/charger, will use anything as long as the plug fits the jack. The label on most chargers gives the polarity, voltage and maximum amperge.

Some universal chargers have a removable tip that allows you to change polarity.

Those are the things a person should check before using them on any device.

Don't forget to preorder your Hatch green chili for this fall. Many vendors ship world-wide.
