Hi ABDUL.SAMAD,

We will have to check the status of the adapter in BIOS; if the adapter is not detected properly the system will continue to receive power but will not charge the battery. Please follow the steps mentioned below to check if the adapter is detected properly.

1. Start the computer by pressing the power button
2. Press the F2 key 2-3 times
3. you will now be on the BIOS screen
4. Under the Main Tab look for the option that says AC Adapter Type
5. If the Adapter Type says Unknown or None with the adapter plugged in.
6. Reconnect the adapter to the machine and if the status now shows as Unknown then the AC Adapter needs to be replaced.

Also, I would suggest that you run the diagnostics on the computer after the above steps by following the steps mentioned in the video below and check if there is any issue with the hardware on your system.

Thanks DELL-RAVI BC for reply.

I have followed the both procedure you have suggested. on BIOS screen Adapter type says 65 W. And when I run the diagnostics my laptop passed all tests.

I want to tell one more thing that my laptop have face this problem only when i plug in adapter after more than 30 minutes of turn on it (when laptop is heat ). and if i turn on laptop and then immediately plug in or plug in with in 5-10 minutes then there is no problem ( laptop does not turn off).
