Client says he got it from new, no liquid, no EFI password.

Wont show serial number and model.
Checked with a few systems, after resets etc same issue.

Any idea why and how to fix it?

Will new 'BIOS' chip with serial number from bottom case help?

Thanks

Serial number must be inserted and need to fix checksum of Fsys region.
Medusa can do all the job onboard.
If not available, upload your BIOS backup somewhere.
