IdeaPad Flex 5i Gen 9 Touchscreen Unresponsive Fix
The touchscreen on the Lenovo IdeaPad Flex 5i Gen 9 can become unresponsive or lose touch detection after a Windows update, driver conflict, or sleep cycle. The steps below restore touch input reliably.
Toggle the touchscreen in Device Manager Fastest fix
Open Device Manager → Human Interface Devices. Find HID-compliant touch screen, right-click it, and choose Disable device. Wait five seconds, then right-click and choose Enable device. This restarts the touch digitizer and resolves most touch failures without a reboot.
Update the HID touchscreen driver
Go to Lenovo Support, search for IdeaPad Flex 5i Gen 9, and download the latest touchscreen driver under Input Device. Run the installer and restart. Windows Update sometimes replaces the Lenovo-optimized touch driver with a generic version that causes partial or complete loss of touch input.
Calibrate the touch display
Press Win + R and type tabletpc.cpl. In the Tablet PC Settings dialog, click Calibrate under Display and follow the on-screen dot-tapping prompts. Miscalibration after a resolution change or external monitor switch can cause the touch position to be offset from where you actually tap.
Clean the screen and remove screen protectors
Moisture, oil, or thick screen protectors can interfere with capacitive touch sensors. Power off the laptop, wipe the screen with a dry microfiber cloth, and remove any screen protector. Test touch response again before continuing with software fixes.
Update the BIOS
Go to Lenovo Support and install the latest BIOS for the IdeaPad Flex 5i Gen 9. Lenovo releases BIOS updates that improve touch panel communication on 2-in-1 models, particularly after the laptop is used in tent or tablet mode for extended periods.
Common questions
Touch works but is offset — what is wrong?
Run calibration via tabletpc.cpl. An offset usually means calibration data needs to be reset.
Touch stopped working after sleep — why?
Toggle the HID Touch Screen in Device Manager to restart the digitizer without a full reboot.
Can I use a stylus on the Flex 5i Gen 9?
Yes. It supports an active stylus using the MPP 2.0 protocol. The Lenovo Digital Pen 3 is compatible.
Is the touch screen replaceable?
Yes, but it is a full display assembly replacement. Contact Lenovo Support for out-of-warranty repair pricing.

Frequently Asked Questions
Why does the touchscreen stop working after sleep on the IdeaPad Flex 5i?
The HID touch digitizer sometimes fails to resume correctly after a sleep or hibernate cycle. Toggling the HID-compliant touch screen entry in Device Manager instantly restores touch without requiring a full reboot.
Can a Windows Update break the touchscreen?
Yes. Windows updates can replace the Lenovo-optimized HID touch driver with a generic one that does not support all touch features on this model. Reinstall the correct driver from Lenovo Support after any update that disables touch input.
Does the IdeaPad Flex 5i Gen 9 support multi-touch and stylus input?
Yes. The Flex 5i Gen 9 supports ten-point multi-touch and is compatible with MPP 2.0 active styluses including the Lenovo Digital Pen 3 for pen input and drawing.
What if the touchscreen is completely missing from Device Manager?
If the touch screen entry is absent entirely, check the BIOS to confirm the touch device is enabled. Go to BIOS Setup (press F2 at boot), navigate to the Input Device section, and ensure the touch panel is not disabled.
