I have a HP DV9000 and I bought a new AC adapter because the computer fell and the tip of the power cord broke. When I first used the new adapter, it charged the computer to 100% and then it started to discharge and it won't get back up to 100%. It seems to stay around 70 and then starts to recharge again but not to 100. Do you think there is something wrong with the power cord or is it my computer. I don't think it is my battery because I replaced mine with one from a friends computer like mine and the same thing happens. I have to know soon so I can send the cord back.

Thanks for any help you can offer.

Was the new AC adapter a direct HP replacement? Was it new? – Dave M Dec 16 '12 at 19:23
is the AC adaptor voltage the precise same as the factory one? does it heat abnormally when plugged in? – Lorenzo Von Matterhorn Dec 17 '12 at 14:31
