Lenovo Yoga 9i Gen 8 Stylus Pen Not Working Windows 11: Fix Guide

The Lenovo Yoga 9i Gen 8 is a premium 2-in-1 convertible that comes with the Lenovo Precision Pen 3 for note-taking and creative tasks on its touchscreen display. When the stylus pen stops working on Windows 11, drawing and handwriting input becomes unavailable. This guide covers every cause and fix.

Why Lenovo Yoga 9i Gen 8 Stylus Pen Is Not Working

Lenovo Pen Driver Missing or Overwritten

The Lenovo Precision Pen 3 requires the Wacom AES or AAAA battery driver for full pressure sensitivity and tilt recognition. If Windows Update replaces this driver with a generic HID pen driver, the stylus may still move the cursor but lose pressure levels and button functionality. Reinstalling the Lenovo pen driver from Lenovo Vantage or Lenovo support restores full pen capability.

Lenovo Vantage Pen Settings Not Configured

Lenovo Vantage manages pen-specific settings for the Yoga 9i Gen 8 including pressure curve adjustment, button mapping, and palm rejection strength. If Lenovo Vantage is outdated or not running, these settings reset to defaults or stop responding. Symptoms of a Vantage-related pen issue include:

• Pen pressure sensitivity feels different from before a Windows update
• Stylus button shortcuts no longer work as configured
• Palm rejection too aggressive, causing missed strokes
• Pen tip click does not register in creative applications

Pen Battery or Bluetooth Pairing Problem

The Lenovo Precision Pen 3 uses a rechargeable battery. If the pen battery is depleted, the stylus shows no cursor movement or only partial functionality. Additionally, Yoga 9i Gen 8 stylus shortcut buttons require Bluetooth pairing to work — if Bluetooth is disabled or the pen is unpaired, buttons do not function even though tip input works normally.

How to Fix Lenovo Yoga 9i Gen 8 Stylus Pen Not Working

Step 1: Charge Pen and Repair Bluetooth Pairing

1. Connect the Lenovo Precision Pen 3 to charge via its magnetic charging connection for at least 30 minutes.
2. Open Settings, Bluetooth and devices, and look for the Lenovo Pen entry.
3. If the pen appears as Disconnected, click Connect or Remove device and re-pair it.
4. To re-pair: hold the pen button until the LED flashes, then select Add device in Bluetooth settings.
5. After pairing, test pen tip input and button shortcuts.

Step 2: Reinstall Pen Driver via Lenovo Vantage

Open Lenovo Vantage and check the My Device section for any pending driver updates. Install any pen driver, input driver, or HID updates listed. After updating, restart the laptop. If Lenovo Vantage does not show a pen driver update, go to the Lenovo support website, enter your Yoga 9i Gen 8 model, and download the pen driver manually from Drivers and Software.

Step 3: Recalibrate Pen Input in Windows Settings

Open Control Panel, Hardware and Sound, Tablet PC Settings. Click Calibrate and select Pen input. Tap each calibration crosshair precisely with the pen tip. Save the calibration. After calibrating, test pressure sensitivity in a drawing application like Microsoft Paint or Krita. If pressure is still missing, check the pen driver version in Device Manager under Human Interface Devices.

Frequently Asked Questions

What pen does Lenovo Yoga 9i Gen 8 come with?

The Lenovo Yoga 9i Gen 8 comes with the Lenovo Precision Pen 3 in the box. It supports 4096 pressure levels, tilt recognition, and shortcut buttons that require Bluetooth pairing for full functionality. The pen uses a built-in rechargeable battery and connects magnetically to the laptop for charging when not in use.

Can I use a third-party stylus on Lenovo Yoga 9i Gen 8?

Yes. The Yoga 9i Gen 8 supports Microsoft Pen Protocol (MPP) 2.0 and Wacom AES compatible styluses. Third-party MPP 2.0 pens from Microsoft, Samsung, and Wacom work with basic input. Full pressure sensitivity and button mapping may require the Lenovo pen driver. The Lenovo Precision Pen 3 provides the most complete integration with Yoga 9i Gen 8 features.

Why does pen input work but buttons do not?

Stylus buttons on the Precision Pen 3 require Bluetooth pairing to communicate shortcuts to Windows. If Bluetooth is disabled or the pen is unpaired, tip input still works (it uses the screen digitizer), but button presses are not transmitted. Enable Bluetooth, pair the pen, and verify button mapping in Lenovo Vantage pen settings.

How long does the Lenovo Precision Pen 3 battery last?

The Lenovo Precision Pen 3 provides approximately 100 hours of use on a full charge. Charging via the magnetic connector takes about 25 minutes for a full charge. If the pen stops working suddenly during use, charge it for 15 minutes and try again. The pen has a small indicator LED that flashes when battery is low.

Conclusion

Lenovo Yoga 9i Gen 8 stylus pen not working on Windows 11 is most often caused by a depleted pen battery, a missing pen driver, or an unpaired Bluetooth connection. Charge the pen, reinstall the driver via Lenovo Vantage, and re-pair the Bluetooth connection for button shortcuts. These steps restore full pen functionality on the Yoga 9i Gen 8 in most cases.
