Purchased a new Dell Inspiron 6000 (9 cell) battery

The input jack that is soldered to the motherboard (where the AC jack plugs in) probably has a cold solder joint. Thus the laptop switches from battery to AC power. You can try to have the solder joints
re-soldered.

Since you have already replaced the battery and the laptop works with the AC charger, then probably the charge circuit in the system board (mother board) is bad. I have rarely seen an AC charger that will power the laptop but not charge the battery. 99% of the time, if it is not the battery, it is the system board.

Yep, Id get another battery if I was you. I bet it runs down pretty fast too. sounds like one of the cells in the battery is dying.
Now if this is a new generic battery off ebay or an Amazon type store then those typically dont last very long so it could still be a dead cell. To get a good as OEM battery you usually either need to spend the bucks or rebuild it yourself. I dont suggest trying to do that unless you are really into electronics and soldering etc.

I would say that the power management portion of the system board is probably faulty if it behaves the same with both the factory battery and the aftermarket.

Many systems have the charge controller and battery interface on a separate board but unfortunately on the Inspiron 6000 it's integrated.

FYI, Here's a copy of the service manual for that system: http://support.dell.com/support/edocs/systems/ins6000/en/sm/index.htm

suspected faulty battery. replace the battery.

Try taking out battery and plug in power. If it works, battery is faulty. If not,
Try taking out your hard disk plug in power, if it works, hard disk is faulty. If not,
Try taking out memory card, if there's a sound, memory card faulty. If no sound, it's your motherboard that is causing the error.

Note: If machine is under warranty no need to pay for the repairs.

Depends on your use. The 9 cell will hold a charge for about 2 hours, depending on your configuration and the 12 I believe is 3-4.

Try removing the battery and see if the laptop powers on. If it still doesn’t power on then either the motherboard is defective or the AC adaptor may have a broken wire in the cable.

Hi
Update laptop bios go dell.com check for update of your laptop model....
Thanks

You can also pick up the batteries less expensive than most computer places at batteries plus. And yes it sounds as though it is the batteries charge is getting low, especially if it runs fine when the battery is out and you have it plugged in.
