    always showing this message AC adapter = Unknown

    The customer gave me this for changing the old battery, and then I replaced the new battery. always showing this message. I changed many chargers and programmed the new BIOS as well. Does someone have any idea for this message?

    Yes. The adapter is pin is not being detected properly. Confirm the adapter dc socket is not loose. This is the center needle pin in the OEM power adapter.

    This pin is required to enter the board and travel through a 1-wire interface to the EC. Sometimes, the TVs esd diode becomes defective and will raise this issue.

    Many cases on this forum and the resolution. Search for ‘PS_ID’.

    Share the full details of the logic board and the schematic link if you require more assistance.
