Battery not charging.

So I gather the laptop does not run when the battery is in and the AC adapter is not connected? Laptop batteries tend to ware down over time and will need to be replaced as they end up not being able to hold any charge. Look online for a new replacement of the battery under the model number of your laptop

Firstly, try the following steps to check the problem:

Turn off laptop.

Unplug AC power adapter.

Remove battery.

Replace AC power adapter.

Turn on laptop, allow OS to boot.

Once logged in to the machine, perform a normal shut down.

Unplug AC power adapter.

Replace battery.

Replace AC power adapter.

Turn on laptop, allow OS to boot. The battery should once again be charging as normal.

Try to change the cmos battery?

You either have one of the following:
1. Bad Battery
2. Wrong adapter - yours no comprende w/ unit.
3. Cracked Jack - means you've got to get a tech to take the unit apart and replace it. $150-200
4. Goto your device manager, double click bat., then right mouse click on acpi driver and update it. Hopefully that works.
or
5. Dell needs to shoot out a bios flash fix.

A) The Battery is old, and beyond charging

B) The AC adapter (Charger) may be bad, and/or one of it's cables may be bad. If there is no one to test it with a multimeter, take it to a computer repair shop, and have it tested.

If bad suggest you look around at prices on the internet, before buying one from the repair shop. (If offered)

C) The port on the laptop, that the AC adapter (Charger) plugs into, is the DC Power Jack. (May be labeled as DC IN )

This jack may be soldered directly to the motherboard, in the laptop, or is attached to a cable which plugs into the motherboard.

For the style that is soldered directly to the motherboard, it's solder connections may have received damage.
Normal plugging in, and unplugging, may have cracked it's solder joints.

Bad connection caused by cracked solder joints, could = no power to battery. (Even though the laptop May be receiving power)

If laptop operates fine on the AC adapter, but the Battery will not charge, the problem may be a power sensor chipset, on the motherboard. May require replacement of the motherboard.

{ This chipset senses;
A) When the battery needs a Full charge, or just a trickle charge.
B) When the battery needs No charge, and power just goes to the laptop.
C) When the Battery needs a trickle charge, or full charge, and the laptop also needs power }

Problem description:The battery charges only when the laptop turned off. The battery charge LED lights up as normal and the battery gets charged to 100% while the laptop is off.
When the laptop is turned on, the battery charge LED goes off even if the adapter is still plugged in.
Possible cause:1. AC power adapter failure.
2. Battery failure.
3. Broken/loose power jack.
4. Motherboard failure.
Possible troubleshooting steps and repair solution:1. This problem could be related to a faulty AC power adapter. It's possible that the AC adapter doesn't provide enough power when plugged into the laptop. To find out if this is your problem, you'll have to test the laptop with another working adapter.Replace the adapter if needed.

2. There is a slight chance that you have bad battery. Test the laptop with a know good battery and replace the faulty one if needed.

3. The battery charge problem could be related to the power jack. Maybe the jack is broken or not making good contact with the motherboard. It is necessary to remove the motherboard and take a closer look at the power jack. Resolder or replace the jack if needed.

4. If the power jack is in a good working shape and new power adapter with battery do not fix the problem, most likely you have a faulty motherboard. Replace the motherboard if needed.

first, you need to try to power on your laptop with another battery with the AC adaptor plugged in. if your problem was not solved you need to check the power jack on your mothernorad.

You have a bad or loose DC connector on the system board:

Symptoms of a broken power jack
1. If you wiggle the power cord or the AC Adapter connector on the back of the laptop, the power LED and battery charge LED start to flicker.
2. Battery will not charge in the laptop.
3. Laptop runs fine off a charged battery.
4. With the AC Adapter connected the laptop appears to be dead.
No power LED or battery charge LED activity.
5. Laptop randomly powers off without any warning.

If your laptop is out of warranty, then you can fix the problem by resoldering DC-IN jack on the system board. If it

You might try cleaning the battery compartment. Makeing sure there are no damaged pins. Often times even a single messed up pin will cause this. Also this is a very good indication of adaptor failure. If you haven't allready I suggest getting another ac adapter specific to you machine. Even a substitute will casue the same issue you are now experianceing.

It sounds like there is a problem with your motherboard. You would have to take it someplace to run diagnostics on it. It may be time for a new laptop
