Re: My laptop battery won't charge
Possible when the old AC adapter blew it took part of the power management circuit with it, This is the circuit that detects and charges the battery,
I'm not sure whether this a seperate replaceable daughter card or whether it is part of the main motherboard.

Laptop batteries power a laptop when it is not connected to an electrical outlet. If the laptop battery fails to charge when the laptop is plugged into an electrical outlet, the battery is likely dead and needs to be replaced. Unfortunately there is no way to fix a dead battery. However, while a dead battery is the likely cause, it is not the only cause. The AC adapter may be broken, in which case the battery won't charge, or the battery contacts may be dirty and need cleaning. Prior to replacing the battery, perform simple tasks to ensure a dead battery is the cause of the problems.
1.Power down the laptop. Gently pull the AC adapter from the side of the laptop for removal.
2.Place the laptop in front of you, bottom side up. Locate the battery release mechanism. This can be a button that slides or needs to be pushed to unlock or release the laptop battery from the housing unit. Press or slide the mechanism. Slide or lift the battery from the battery bay for removal.
3.Insert the AC adapter into the side of the laptop. Power on the laptop. If the laptop does not power on, ensure the AC adapter is securely plugged into a working electrical outlet. If the electrical outlet is working and the laptop won't power on, the AC adapter is not properly working and needs to be replaced. Remove the AC adapter.
4.Dip a cotton swab in a small amount of rubbing alcohol. The cotton swab should be damp, not dripping wet. Lightly rub the dampened cotton swab onto the battery contacts and battery bay contacts to remove dust, buildup and grime. Allow the contacts to air dry.
5.Align the battery over the battery bay. Either press or slide into place. A clicking or snapping noise produced from the locking mechanism will confirm the laptop battery is securely locked into place.
6.Install the AC adapter. Allow the AC adapter to fully charge the battery for 8 hours.
7.Remove the AC adapter. Power on the laptop. If the laptop does not power on, the battery needs to be replaced.
You either have a faulty ac adapter; a bad power supply in your laptop; a bad battery; or a blown LED indicator light.
1. If the connection is not loose when you plug in your ac adapter try letting the laptop charge for a while. (If you are using the correct ac adapter)
2. Try removing your battery and using the ac adapter. If this works the battery is bad.
3. Try a new ac adapter.
4. Power supply is bad
just had the same problem- the socket where you plug in the adapter had shorted out-needed to be resodered-no big~100$ BUT my ac adapter was bad as well- may have caused the short (they are cheap on ebay)
the motherboard on your laptop is shorted to the ground. It happens when you unplug the ac adapter cord from the back of the computer a lot. Call Dell's reknowned tech support and ask for the motherboard to be replaced.
