Charger fluctuating while laptop is on

Question

Model: G3 3579 Whenever I plug in my laptop in its ON state, there is fluctuation in charging. The battery notification in the down right corner keeps on jumping between plugged in and not charging. The charging light on the laptop keeps on switching ON and OFF. The frequency of fluctuations varies from seconds to minutes. Also this only happens when the laptop is being used, If the lid is down then there is no fluctuation in charging. What should I do?? PS: all my drivers and BIOS are up to date.

Hi @cyk00 welcome to this user to user discussion forum. This is not Dell Support.

The ac adapter's diagnostic LED is saying there is intermittent power connection between laptop and ac adapter. How to Identify AC Adapter Damage on Dell Systems | Dell US How to Troubleshoot AC Adapter Issues on a Dell Laptop | Dell US If you have access to another Dell ac adapter, please use this to determine that ac adapter is OK and laptop has a problem. Check external dc-in socket on the laptop for damage, dust, foreign objects, etc.

Support for Dell G3 3579 says dc-in socket power adapter port is easy to inspect, after remove base cover.

Hopefully the cause of the intermittent power connection will be revealed so that corrective action can be undertaken.

Most Probably you are dealing with a Loose DC in port.

Try wiggling the charger cable in the port and see if you can replicate the issue.

While a loose port could very well be the issue here, especially if charging states change in quick succession, this could also simply be:

A feature of your laptop's power manager software that tries to prolong your battery's useful life by limiting charging cycles. Sometimes you can tweak this via settings by switching from a 'battery saver' profile to something else.
A faulty power manager or battery driver. Performing an uninstall-reinstall can fix this.
