Symptoms
- Pen doesn't register on the screen or tablet at all
- Cursor jumps but pressure sensitivity doesn't work
- Pen works in one app but not another
- Pen buttons don't respond
Likely causes
- CommonLow or dead pen batteryMany active styluses use a small battery or capacitor charge that depletes with use.
- CommonPen not paired or out of rangeBluetooth-enabled pens need pairing, and passive ones need to stay within the tablet's active sensing area.
- CommonOutdated or missing tablet/pen driverDrawing tablets and some styluses rely on specific driver software for pressure sensitivity.
- PossibleApp doesn't support pressure sensitivityNot all apps read pen pressure data even if the hardware supports it.
- Less commonWorn or damaged pen tipTips wear down with heavy use and can affect accuracy or responsiveness.
What to do
- Charge or replace the battery in the pen if it uses one, and check for a low-battery indicator in its companion app.
- Confirm the pen is paired via Bluetooth if applicable, or that it's within range of the tablet's sensor.
- Install or update the manufacturer's driver software (like Wacom or Huion drivers) for full pressure sensitivity support.
- Test the pen in the manufacturer's driver test panel to confirm basic function outside of a specific app.
- Check that the app you're using supports pressure sensitivity and that it's enabled in its settings.
- Replace a worn pen tip using the manufacturer's replacement nibs if drawing feels scratchy or inaccurate.
- Restart the computer after installing or updating drivers.

When to call a pro
If the pen doesn't register on the tablet's own driver test panel after fresh batteries and drivers, the pen or tablet's sensor has likely failed.
