Could be many reasons. I've no real answer but some questions that might help.

Is the battery the original Dell one or is it a 'third party' replacement?

Has the battery shown any signs of failing in the run up to this happening?

Is the AC adapter the original Dell one?
Dell use 'coded' mains adapters that are identified by the laptop. Generic 3rd party replacement mains supplies will usually not work.

You could try removing the battery and then press and hold the power button for a few seconds (after first disconnecting from AC mains). Refit the battery and retest.

...seems to be a good battery because it charges very very fast.

That could just be because the battery has lost a lot of capacity, what little it can now hold doesn't take long to charge up. A battery report can tell you the health of a battery, and its remaining capacity.

If the laptop works without the battery then charger is functioning correctly. Take a cloth with a bit of rubbing alcohol on it (or some on-the-go alcohol swabs), and clean the metal contacts that connect your battery to your laptop.

Make sure to install all Windows important updates.

Install latest versions of your laptop device drivers you can download the latest device drivers from the device manufacturer or from your laptop manufacturer website.

Step 1

1. Shutdown your laptop.

2. Remove the battery.

3. Connect the AC power adapter to your laptop.

4. Power on the laptop

5. Open the Device Manager by typing Devmgmt.msc into Start Menu or from Control Panel.

6. Under the Batteries category, right-click all of the Microsoft ACPI Compliant Control Method Battery listings, and select Uninstall (it’s ok if you only have 1).

7. Shutdown the laptop.

8. Insert the battery.

9. Power on the laptop.

If above suggestions wont resolve the battery charge issue then follow below steps.

Step 2

1. Shutdown the laptop.

2. Remove the battery.

3. Start the laptop with only AC adapter connected to laptop.

4. When you login to Windows OS connect the battery while Windows OS working.

Step 3

Reset the System Management Controller. Use one of these methods to reset the SMC, which controls battery management, battery status light.

1. Shut down the computer and disconnect the power cord.

2. Remove the battery.

3. Press and hold the power button for ten seconds.

4. Reattach the battery and AC power adapter, then start up the laptop.

Hopefully one of the above suggestions will help you resolve the battery not charging problem. If battery still doesn't charge, you may need to replace your battery.

you said
6. Under the Batteries category, right-click all of the Microsoft ACPI Compliant Control Method Battery listings, and select Uninstall (it’s ok if you only have 1).

by the above statement, do you mean if Microsoft ACPI Compliant Control is written only once, then I should not be uninstalled, and if it is written more than once, then it should be uninstalled?

i performed step 2 and it failed to fix the problem, then I applied step 3 to fixit, but it didn't fix the problem.

Like i said if you are following the steps i write down and nothing works then it's dead battery that is not charging and need replacement, you can also boot your computer with live Ubuntu USB flash drive to see problem software or hardware related.
