Try these steps in order:
- Confirm compatibility
- Make sure the Surface device supports pen input. Some models (for example, Surface Laptop 13-inch 1st Edition, Surface Laptop 5G for Business, Surface Laptop 7th Edition, and all Surface Laptop Go devices) do not support Surface Slim Pen or Surface Pen and will not ink even if the pen is paired.
- For full details, see Surface Pen compatibility and features from the Surface Pen help page.
- Verify the pen is charged and paired correctly
- Ensure the Slim Pen is fully charged using its compatible charger or keyboard storage tray.
- Check Bluetooth: the pen should show as Connected in Bluetooth settings. If needed, remove it from Bluetooth devices, restart the Surface, and pair again:
- Press and hold the top button for about 5–7 seconds until the LED blinks continuously.
- Go to Bluetooth settings and select Add device, then choose the Surface Slim Pen and complete pairing.
- Restart the Surface device
- Select Start > Power > Restart. A restart often restores the connection between Surface and the pen.
- Test in multiple apps
- Try inking in apps such as OneNote, Sticky Notes, or Paint.
- If inking works in some apps but not others, the issue is likely with the specific app’s pen support.
- If the pen does not ink in any app, continue.
- Check health and updates in Surface app
- Open the Surface app (install from Microsoft Store if needed).
- In Help & support, check update status and select Check for updates to open Windows Update and install any available driver/firmware updates.
- Restart if prompted and test the pen again.
- Check pen LED behavior
- Press and hold the top button and observe the LED:
- Continuous blinking: pen has power and is trying to pair; restart Surface and re-pair if needed.
- Red or amber: low power; fully charge the Slim Pen and test again.
- No LED at all even after charging: the pen may have failed and need replacement.
- Press and hold the top button and observe the LED:
- If the pen still does not work
- If there is no LED after charging, or the pen remains non-functional in all apps despite being connected and the Surface being updated, request a replacement:
- Go to the device service page, sign in, ensure the Surface is registered, choose it, then select Accessory and the appropriate Pen issue type to see replacement options based on warranty.
- If out of warranty, consider purchasing a new pen from Microsoft Store or other retailers.
- If there is no LED after charging, or the pen remains non-functional in all apps despite being connected and the Surface being updated, request a replacement:
