Researched same problem for HP dv9543/9500 9000 series;

Had similarly hoped it was the power jack feet with broken solder...unfortunately not. On dis-assembly I found that the socket is designed to preclude this by having its own mini-board and then a cable goes from there to the motherboard.

It appears to be likely a charging chip or similar.

You likely can run the laptop by charging the battery, which tells you that the laptop is otherwise functioning normally.

As a stop-gap solution you can get an external battery charger that will connect to the battery directly (EBay); two batteries and you can alternate.

And/or the HP-Dock which will power the laptop via the cardbus slot with a cable connecting them.

Also saw on ebay a vendor that would fix the charging circuit section (or other issues) for $75 I believe.

Unfortunately, my laptop was with the offspring overseas in the jungle, and had to send another motherboard to him via a friend.

Further unfortunately, the replacement motherboard had the graphics chip heat problem alluded to by the first answer person; and the graphics chip had to be used from the original motherboard.

The laptop failed within warranty but was of course not here nor was I told of the problem until after expiration; have 3 of the same model laptop--flagships of the time with two hard drives.

another ebay outfit will reinstall the NVidia GSM-8000 or something graphics "board"/chip with a copper pad or something to solve the heat dissipation problem.

(now it is back nearly a year later with the video off, so assume the chip overheating problem--had it working for awhile--now off)

hope the info may help
