Active Stylus for ThinkPad tablets

The Lenovo 4X81P44052 is an active stylus finished in Storm Grey. It is built for precise input on compatible ThinkPad 2-in-1 and detachable tablets. The pen supports natural writing, sketching and annotation workflows. It draws power from the host device and requires no separate battery.

Suited for pen-enabled ThinkPad users

This stylus works with the ThinkPad T14s Gen 5, X1 2-in-1 Gen 9 and X12 Detachable Gen 2. Buyers who need a pen for non-ThinkPad tablets or for ThinkPad models not listed above should look at something else. It is not a universal capacitive stylus and will not function on unsupported screens.

Compatibility list decides fit

The single specification that determines whether this is the right part is the explicit model compatibility list: ThinkPad T14s Gen 5, X1 2-in-1 Gen 9 and X12 Detachable Gen 2. If your device is not on that list, the stylus will not pair or register input. No other specification overrides this requirement.
