The AC power adapter wattage and type cannot be determined after bios update.

This question has suggested answer(s)

Hell there,

Yesterday I went down to my local electronics store and bought an XPS l502x. I love it once I got it set up, but noticed it was a little behind on its BIOS updates. I updated the bios hoping it would help with the game play in Diablo 3, but on next boot up I was informed my laptop could no longer determine the wattage of my adapter. I went to bed and decided to deal with this today and got no error. Should I be looking out for something being broken or did the adapter just need a rest?

  • Hi Holojack,

    Welcome to Dell Community

    It seems you  are facing issues where in system is unable to determine the ac adapter.

    The Dell™ XPS™ L502X ships with 90-Watt or 130-Watt dapters. The LED on the adapter is a Blue Ring around the connector which glows when there is power supplied to the adapter.

    Please refer to the link below to confirm if you updated the system BIOS as per the same:

    In case not, follow the instructions on the link to download the latest BIOS and install the same on the computer. Once done, system would ask for a restart.

    Kindly reply with the result. Glad to help

  • Upon restart, I had the right BIOS, my setup/BIOS reads it at 130 watt. My question, however, is if I should think about getting a new one since I had previously stated that it did charge again on start up. I am new to laptops, so I wonder if you use the adapter for too long , does it need to cool down before it can be read?

  • Hi Holojack,

    Thank you for the response.

    Upon restart if the BIOS version appears to be correct, you may not update the same.

    I would like to advise you that once the laptop battery shows as 100% charged, please disconnect the ac adapter. Connect the ac adapter only when the system shows the "Battery Low" message and needs to be charged.

    When the laptop is not is use, it is recommended to keep it turned off.

    As you are new to laptops, please find below the links for XPS L502X System Setup and Service Manual respectively with all necessary information:
