Laptop Battery

I’ve been running my HP Pavilion zd8000 exclusively off the laptop AC adapter for about 1.5 years now and just the other day the laptop no longer runs off the adapter.What happens is that it will charge the battery if the laptop is off, but as soon as I turn on the laptop the adapter shuts off (light goes out) and the laptops begins running off the battery. To get it to charge the battery I have to unplug the AC adapter, shut down the laptop, then plug the adapter back into the socket and the laptop.Did I simply kill the AC adapter after 18 months of intense 3D gaming?

 I may as well just remove the battery and run it off the AC adapter. I never bothered to try that, but then I really don’t care about the battery other than as a backup if the power goes out (which is meaningless since in that case the router and the cable modem go down since they aren’t on a UPS battery backup, hehe).I have yet to contact HP support, but sweet jebuz, I hope there isn’t anything wrong with the socket on the laptop.I had another laptop AC adapter handy but it was a 1.5amp and the “broken” one is 2.2amp so not compatable.

 If the AC adapter will charge the battery at all, I say it’s at least not dead. Maybe not acting right, but not dead.On the other hand, if the AC adapter turns off when you turn the lappy on and try to run it off AC power, it would seem that perhaps you have a partial malfunction at the actual plug receptacle on the laptop. Combine that with the possible partial malfunction on the AC adapter, and you have a very frustrating situation.

A couple questions: Have you tried calling/emailing HP tech support about this issue? Have you looked around online for the specs on yours and other models of HP laptops, cross-reference with any friends who might have a compatible AC adapter that you/they know is good? I would say that if the borrowed AC adapter works normally (charges / runs the laptop), it would indicate a problem with yours. If it acts the same, I say the power plug receptacle.
