Windows 11
You flip the Lenovo IdeaPad Flex 5 Gen 8 into tablet mode and the screen stays in landscape instead of rotating. The AMD Ryzen 5 7530U convertible relies on accelerometer sensors and the convertible mode driver, and a stopped sensor service or a stuck rotation lock is the usual cause.

Fix 1 — Disable Rotation Lock
Fold the screen past 180 degrees so the IdeaPad Flex 5 enters tablet or tent mode. Open Action Center with Windows + A and check the Rotation lock tile is off. If the tile is missing or greyed out, Windows has not detected the mode change, which the next fixes address.
Fix 2 — Restart the Sensor Services
- Press Windows + R, type services.msc and press Enter
- Find Sensor Service, Sensor Monitoring Service and Sensor Data Service
- Right-click each → Restart, and set Startup type to Automatic
- Fold into tablet mode and test rotation

Fix 3 — Reinstall the Sensor Drivers
Open Lenovo Vantage or Lenovo Support for IdeaPad Flex 5 Gen 8 and install the latest sensor, Intel/AMD HID and Integrated Sensor Solution drivers. In Device Manager → Sensors, a yellow warning on the HID sensor collection confirms a driver problem to reinstall.
Fix 4 — Update BIOS via Lenovo Vantage
Lenovo Vantage → System Update. Install any BIOS or firmware updates for the IdeaPad Flex 5 Gen 8. BIOS updates correct convertible mode and hinge sensor reporting, which is what tells Windows to switch into tablet mode and enable auto rotate.
