DC Power jack heats up to very hot to touch on HP NX9010 laptop.
The
DC jack, where you plug the power adapter cable, might be loose or
defective, & needs to be either re-soldered or replaced.
In order to do this, the laptop needs to be disassembled
& the motherboard taken out. Also, the motherboard needs to be checked for defective/burned out components in the
area near the DC jack. Any defective/burned out components found should
be replaced, or you might need to replace the laptop's motherboard
altogether.
