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 you to update the BIOS on the system and check if the Battery is charging. Please enter your service tag # on the link below, select the OS, then download the BIOS from BIOS section onto the system and install it.
I did as you said. The system seems to recognize the AC adapter, as it says '130 W 'instead of 'Unknown' or 'None'. My BIOS also seem to be updated, as they are recognized as A16 and when I opened the file with the new BIOS it said I already have the current version and that it's not recommended to flush them.
I have the feeling the battery is still getting power from the adapter, but that the system is unable to detect or display when it's disconnected for some reason. I figure this because when I disconnected the adapter and restarted the system without it, the charge level on the battery did fall (though it still claimed to be connected and charging) . When I reconnected the adapter the percentage began to rise again until it got to full. It's an odd problem indeed.
When checking on Safe Mod and going to the battery meter, it read 'Idle' instead of 'Charging' like it did on normal mode. The little indicator on the task bar didn't change, however. Ever since doing this and returning to normal boot mode, the battery indicator has been stuck on 92%.

Hi Chatbork,
Please share the exact system model and the operating system. Did you update BIOS to the latest?

Apologies for the late replay, I've been away for the week.
The model is Inspiron R17 7720, the OS is Windows 8.1, and the BIOS have been updated to A16 recently.
