The essential part of a laptop that makes it portable is the rechargeable battery. Batteries have given devices the much-needed freedom of movement that humanity craves. However, you will need an AC adapter in order to charge your laptop battery. For Dell users, charging their batteries has somewhat been a problem. There is a particular issue that has been bothering several users; as far back as 2005. When the charger is plugged in and the PC is booted up, the user gets an error in a black screen stating “The AC power adapter type cannot be determined”. A variation of this message says “The AC power adapter type and wattage cannot be determined”.


Power cycle your PC

Completely discharging your PC might fix the unresponsive state of the charging system.

   Unplug your charger, power off your laptop, and remove your battery
   Hold down the power button for at least 30 seconds
   Put the battery back in, with the charger and reboot
   Check if this fixed it

Get a new AC adapter/Charger

If you have tried troubleshooting and you have found that your charger does not work on a similar computer or a similar charger works on your PC, then it is time to change your AC adapter. If you are sure your charger worked for an extended period before, then the problem could be anywhere. It could be loose soldering in the charger brick, a broken pin, fried capacitors, a broken connection, etc. If you think you can try repairing the charger (by changing cables, capacitors, soldering) then go ahead. In most cases, the charger cannot be salvaged and you will need to buy a new charger.

Disabling Power Warnings

If you are able to charge your computer normally but the warning keeps coming up, you can make the warnings go away permanently by changing the BIOS settings. Every laptop has settings which determine whether the power warnings will show or not. In this solution, we will navigate to your BIOS and disable the power warnings.

Note: This doesn’t mean that the issue you are facing will go away. We will be simply disabling the warnings.

   Restart your computer and enter the BIOS by pressing the DEL key or F2 according to the model of your computer.
   Once in BIOS, go to the Advanced tab and then toggle the option of Adapter warnings. This option may be present in another tab as well.
