Over time I noticed that the 2 most common part numbers that I do come across with these specific laptops were 239704-001 and 239427-001 which is a "HP Compaq AC adapter (65 watt) - 110-240VAC input voltage, 50-60Hz, 2.4A - 18.5VDC output voltage, 65-watt - Requires a separate 3-wire AC power cord with C5 connector".

Also Compatible with: HP Compaq Business Notebook PC nx7000, HP Compaq Business Notebook nx7010, HP Pavilion zt3280US notebook PC (US).

WOW, what a long and confusing list that was to organize even for myself but now it should be self explanatory to anyone reading this. If you need help with anything, I am only a e-mail away and really enjoy the feeling helping others out with any computer problems that may arise. Until next tomorrow, goodnight.

IMPORTANT INFORMATION FOR THIS HP LAPTOP POWER SUPPLY: HP has done it again; new updated replacement part numbers for the new years ac adapter laptop lineup. If your having trouble finding 239704-001... that is because the new 2011 part number is 613149-001 which specs are 100% identical besides the difference in PN's.
