One possibility is that the plugs where the battery is attached are scr...d up. Try to check them and see if there is any obvious problem... If not, there might be a short-circuit somewhere near the battery (in the laptop, not in the battery..)

if u know repairing laptop ,u just open the back case of that and remove full outlet & see where the screen display chip is attached to the motherboard,if u see that u just remove the screws and clean it, afterwords add some heat sink compound to that and attach with screws,this is the best best solution & do it carefully

I had the EXACT same issue on my HP Pavilion DV8000. After reading this thread I started disecting the machine, sure the issue was a faulty internal power plug/cable. It is TRULY a big job, but very doable without special tools. You pretty much have to take every single screw out of the thing to get to that stupid cable.
Here are a few things to know:
1) there are a lot of screws - mainly long black (L 12) and short silver (L 5x2.5). Keep track of all of them in order so you don't end up like me - with 3 leftovers. Lol. There is ONE long black screw that is a little shorted than the others (L 10). This is one I had left over. There are two VERY tiny black ones. I also have one of those left over. There is also a few smaller black ones, too. Just keep them all noted as you remove them and remember where these odd ones go!
2) There are some very flat band cables that plug in to tiny plgs. However thereis no plug on the cable. The flat end just shuves into the plugs. These are very delicate. be gentle with them.
3) When you finally get the housing for the fan loose you can now get to the entire power supply cable. Here is a note: I FIXED my problem by unplugging this cable and plugging it back in. The cable runs under the fan housing, and it seems like you have to remove that housing to get to the cable, but actually it comes out again right next to the processor and heat sink. There is a thin sheet of black sticky insulator tape over the processor and the cable at that point. You'll have to gently remove it. There is not much room there, but you CAN unplug the cable without removing the entire fan housing.
Here is what I did to test this plug and cable. After unplugging it, I shoved a tiny straightened staple (the female plug is very tiny) into the female receptacles for the prongs on the motherboard (red and black only). Then I plugged the power supply in to the power jack. With a DC meter I verified that the female end of the power cable inside the machine was getting juice, and it was.
With nothing left to test, I put it all back together (save three screws) and it is now charging the battery and running from the ad power plug. Whatever I did fixed it!
One last note: There are 4 sequenced screws that hold the heat sink tight. These are under a bit of pressure so the sink is tight. DO NOT remove these as the sink has a heat conducting "goo" that helps it disperse the processor heat. As old as these machines are now, you don't really want to disrupt that "goo" and risk the processor over heating.
I hope all of this typing helps someone.

Hello. There is a hardware failure with the laptop not the AC charger. AC chargers have some range of protections of their own. If the power requirements of the laptop are bigger then what the charger can handle, the charger will turn off. Also other parameters can bring the charger offline. In your case, you have a problem with a small chip, the battery charge controller unit, witch regulates the amount of current required to propperly charge the battery. When this thing fails, the charging requirements for the battery are reported rong and the AC charger is forced to give more power then necesary. This results in disconnection of the AC charger ( an internal fail safe of the AC charger) and the laptop to swich back to battery power. When the laptop is turned off, it can charge the battery because the power requirements are low, having all processor, main board, hard disk etc turned off. Therefore the AC charger can handle the load. However you will need to have it checked by a service center as it is a hardware fault. Both AC charger and laptop needs that check. The charge controll circuit needs to be replaced probably. It will be a somewhat expensive repair. Don't buy any other battery untill you have the laptop checked. For more aditional info please post back. PS. Sorry for my bad english, I am from Romania, it is pretty hard for me to explain tehnical stuff in english.
One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect your hard drive
Test all leads that attach to your hard drive including electrical extensions,IDE,SATA
the leads from your ((motherboard to your hard drive)) make sure they have a secure connection and are not faulty or just replace them there probably old and faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electic extensions or just replace them they are probably old and faulty a computer needs its connections to have an end so any faulty leads will end up with a computer error
hope this helps
