You will have no problems.

The adapters for that model are SMART adapters.

The center pin is used to help regulate the Voltage and Amps.

Perharps I should have been more precise. I have a HP 609940-001 adapter and I do not know if it is smart.

I also have a HP 519330-001 adapter powering my HP 8460p. Is it smart as well?
