The back-panel view (page 6) calls the two small slots PCI-Express x4. The press spec (Wccftech) gives their lane widths as Gen4 x2 and Gen3 x1. The x4 is stored as the mechanical size and the press widths as electrical lanes.

The six generic audio connectors use other because their exact connector type and role are not stated in the table. The PSU AC inlet is stored as AC power input. Source is omitted for it because the enum has no PSU option. Graphics-card outputs are from the exact RTX 5080 row of the family PSREF. DisplayPort 1.4 is physically present with the integrated-graphics 265K. Thunderbolt display routing and maximum USB-C charging power are not guaranteed from the family footnote or PD 3.1 alone.3Maker spec sheet (PDF)psref.lenovo.com/syspool/Sys/PDF/Legion/Legion_T7_34IAS10/Legion_T7_34IAS10_Spec.PDFRead 8 October 2026RTX 5080 row on printed page 3 explicitly gives three DisplayPort 2.1b UHBR20 and one HDMI 2.1b FRL connector.
