BenchReady — Direct display detection before dock troubleshooting Intel machine types 20W0 or 20W1 · 2.0.0 Compare a single monitor through a documented Intel video connection and preserve detection versus image. MODEL FIT Read the underside machine-type label or Lenovo Vantage device details locally. Confirm T14 Gen 2 Intel and 20W0/20W1. Keep the full serial number private. Windows 10/11, original Lenovo firmware. Labels vary between Windows versions; managed systems require IT approval for settings changes. Excluded: ThinkPad T14 Gen 2 AMD; ThinkPad T14 Gen 1; ThinkPad T14s Gen 2; ThinkPad T15 PREPARATION [ ] Built-in screen works [ ] Exact Intel unit and monitor connection confirmed [ ] Powered monitor with intended input selected [ ] Compatible HDMI or Thunderbolt/USB-C video path [ ] Keep any existing backup accessible to you. [ ] Keep credentials and personal files outside this record. GUIDE 1. Use the Intel connector layout: the guide identifies Thunderbolt 4 USB-C and HDMI. A charging cable alone does not establish video capability; check the cable documentation.

Remove the dock from the comparison. Connect one powered display directly through a documented compatible cable and select its matching input.

Right-click a blank desktop area, open Display settings and use the displayed detection control if needed. Record detected-with-image, detected-but-dark or absent.

Review the selected display and mode in Windows. Keep the monitor, input and mode fixed while comparing one known-compatible cable. Use settings supported by both devices.

Only after the direct result is recorded, compare the exact supported dock path. Optional docking connectors differ by configuration; record unsupported or unavailable hardware separately.

Do not open or press on it. Set damaged accessories aside. Do not open mains adapters or force connectors. Do not erase, reset, flash firmware or bypass a lock as a default diagnostic step. OUTCOMES Direct display baseline saved: Retain the working direct path, input and display mode. - Record the monitor/cable details privately. - Keep any separate dock issue with the dock vendor. Review the docking setup: The direct path works while the dock path fails. - Provide exact dock compatibility and power details to its vendor. - Retain direct-versus-dock results. Confirm the connection requirement: A missing or incompatible cable/dock prevents a meaningful display result. - Verify exact Intel unit, connector and cable support. - Keep unsupported conditions Not applicable and unavailable ones Not tested. Share display detection evidence: The direct compatible path still lacks usable video. - Provide detected-versus-absent and dark-versus-image observations. - Include input, cable and Windows display-mode details. Keep the unanswered checks visible: Direct-path compatibility, detection or image availability is unknown. - Provide Intel connector and direct monitor result. - Separate display detection, image and dock compatibility. - Keep unperformed conditions marked Not tested. Ask the provider to confirm these before further changes. Stop the powered checks: Stop using or charging damaged equipment. Keep away from hot or smoking equipment; obtain emergency help for an immediate fire risk. Arrange manufacturer guidance before handling or transport. - Tell Lenovo or your IT team about the visible damage before arranging transport. - Provide Intel connector and direct monitor result. - Do not open the case, remove the battery, press a lifted surface, or continue a test to complete this record.
