Plugged in, charging but won't pass 70%

hi dear there  is no desktop mod in my laptop

Mine is like this... Windows 10, Anniversary Edition... no options associated with extended life.

Great job Dell! The responses to individual posts don't fall in under the post, they are responses to the master post.... making my answer useless. But, since the whole thread is useless, guess it doesn't matter. This Dell has been a great machine, but the help here is pathetic.

I just uninstalled the microsoft ACPI compliant and restarted my laptop entering the battery but the dell extended battery life can not be seen. Please help me to find this back.

Sorry, either this method is incorrect for me or i have mistaken it. please give me a video clip for the BIOS settings.

Please list Dell model number and version of windows. Example: Dell Inspiron 3543, windows 10

In the meantime, I'd  suggest you check status of AC adapter and battery in the BIOS setup.

1. Power off computer.[ make sure AC adapter is connected to computer].

2. Power on computer, quickly start tapping F2 key continuously. You should be in the BIOS now.

Under the main tab, look for the option that says "AC adapter type". If the AC adapter type says Unknown or None then it's most likely a problem with the adapter. Note: You can wiggle adapter while checking it in the BIOS.

Under Advanced tab, look for Battery Health, it should say "Battery Is Performing Normally". If it says any other message then it's a problem with the battery and most likely needs to replace with a new battery.

Please keep this in mind:

There are different power managements setting that might prevent 100% charge. One such is Dell Quickset application - Battery Meter App). It would look something similar to the images below:
