TPM 2.0 FIPS 140-2 certification4Maker spec sheet (PDF)assets.grandandtoy.com/assets/Manufacturer-Brochure/10/87/1087298242.pdfRead 7 October 2026Original Security row explicitly identifies TPM 2.0 FIPS 140-2 Certified, retained as a component certification rather than whole-laptop FIPS. Adjacent TCG Certified text runs directly into Windows Hello fingerprint-reader/camera wording without a separator, so TCG component binding is ambiguous and that list item is omitted. Eyesafe technology wording is not promoted to an unproved certificate.
