The Tilt Pen MPP 2.0 is officially compatible with the HP Pavilion x360 15-er1000 series, according to the manufacturer’s compatibility list. If your device is a standard HP Pavilion 15 (not a convertible x360 model), it does not support active pens like the Tilt Pen MPP 2.0. For absolute certainty, check your device’s specifications or contact HP support directly, as compatibility can vary even within similar model numbers.
