HP's Smart adapter option kits include a legacy dongle so that they are backwards compatible with older HP notebooks, providing an unprecedented level of commonality. Customers wanting one common AC adapter for all their HP Business Notebooks and docking stations can use the new HP 65W Smart AC adapter. The HP 65 Watts AC Auto Air Combo Smart Adapter allows you to power and charge your notebook while in the office, at home, or in the car, and offers you the additional capability of powering your notebook on any airplane. The convenient charging switch allows you to toggle between charging and power only voltage levels so you can charge your battery while in the office or in the car, and power while on an aircraft.
I bought this adapter directly from HP 2 months ago. It has been finicky for the last month, but now has completely quit working. I called HP to have it replaced, but was informed that because it was out of the 21 day warranty that I was out of luck, but they would be happy to sell me another one for $70.If you choose this adapter all I can say is good luck. HP's customer service was completely worthless.
I should have listened to the other reviews of this product.....I thought I was purchasing "original" equipment (I don't think HP makes the original power cord to my HP Compaq nc6120 at least I haven't found it). This power cord comes in 3 pieces. You have an apdapter plug that actually fits on the end of the power cord and that part goes into you "line in" port. ***It NEVER makes a good connection....let me re-phrase that to "it did at first" but now (4 weeks later) when I plug in the power cord it NEVE..
