Re: Dell C400 Laptop Battery not charging
Go into the battery properties and check if the battery is charging. If it says it is, then test it, use the battery to see if it really is charging, they will sometimes give a false reading. If it's not charging, then check the power supply with an ohm meter for the proper output. If this all checks good, but the battery isn't charging, then I'm afraid you have a failed power management system on the motherboard. The power management system controls the charging along with other power related aspects of the machine. If the power management system has failed, then unfortunately, you will have to replace the motherboard in order to fix it.

So put the old power cord back on since you say it charged the battery normally. Why did you change it if it was charging the battery? It's quite possible that the new power cord is faulty. Just because it is new does not mean it works.
Remove the battery and plug the new power cord in. Does it boot the laptop up? Are you able to function with the new power cord plugged in. If so, then your battery is more than likely dead and needs to be replaced. The battery only has a useful life and once it is completely bad it will not charge.
I know this sounds simple but have you checked the power connections at the brick (middle of the power cord) often this comes loose and is not noticed until battery is dead. The leds staying dim is what made me think of this. They will go out when on battery only especially if power cord is not producing any power. When you plug in the laptop do you see a little battery charging light come on?
Try removing your battery pack. Then connect the power adaptor (even without the battery) and connect is directly to the power outlet. If it powers up, then the battery pack might be defective or totally drained.
If the battery is just totally drained, simply place the battery to the laptop. Do not turn the laptop on. Plug the power adaptor to the laptop and plug it to the power source. If you see that the charging LED is blinking in your laptop, then just leave it charging up to 5 to 8 hours.
Never use a laptop on battery mode while it is plugged in to a power source. This is the number 1 reason why laptop batteries don't last longer.
