This 65 W AC adapter supplies 18.5 V at 3.5 A for HP Dv5135nr, Dv5136eu and Dv5137ea laptops. It accepts 100‑240 V input at 50‑60 Hz and includes the AC power cord.

Questions about this item

How do I install the AC adapter, and what connector detail do people often get wrong?

Plug the DC connector into the laptop power port; the inner diameter is 1.7 mm and the outer diameter is 4.8 mm, so verify both dimensions match before forcing the plug.

What maintenance or replacement will this adapter need over time?

The included AC power cord and the adapter unit itself may require replacement if the cable frays, the brick overheats, or the output drifts from 18.5 V at 3.5 A.
