    Dell 5285 2-in-1 with LA-D89 mb. TPM issues

    Howdy all!
    I've got a Dell "surface" 5285 with an LA-D89 "Pebble Beach" motherboard. It was offloaded to my wife a few years ago by her company, which she's since been laid off from. I'm trying to rebuild it but there is an admin PW on the bios, and I've found that TPM 2.0 is built in. I've taken it apart and scoured the internet looking for a way around the TPM, or to ID the chip to remove it.

    I've gotten nowhere, and not fast. :-(

    Looking for help as I'm close to pitching it, unless a new SSD would let me load Ubuntu or Windows..

    Thoughts or suggestions?

    Thanks in advance

      BIOS passwords aren't stored in the TPM. Usually in the BIOS EEPROM itself or the EC.

      Quick search on this forum shows it's in the BIOS. You need to make a dump of your BIOS EEPROM and upload to the BIOS group for pw removal. If you have no experience with soldering/programming, you might want to source someone who can.

          yeah.. I don't solder or program. I'll see if I can source someone local.

          appreciate it..
