Surface Pens pair via Bluetooth, not USB — here's how to set yours up
A Surface Pen connects wirelessly to your device through Bluetooth. Unlike older styluses, you don't plug it in or dock it to pair. Instead, you turn on Bluetooth on your device, put the pen into pairing mode, and let them find each other. The whole process takes about a minute.
The exact steps depend on which Surface device you own — Surface Pro, Surface Laptop, Surface Go, or Surface Studio — but the pairing method is the same for all of them. Once paired, the pen stays connected as long as Bluetooth is on. You'll need to replace the pen's battery (usually a AAAA battery) every few months depending on how much you use it.
Key Takeaways
- Surface Pens connect via Bluetooth, which must be turned on in your device's settings before pairing will work.
- To enter pairing mode, press and hold the top button of the pen for three to five seconds until the LED light blinks.
- Once paired, your pen will reconnect automatically whenever Bluetooth is on, so you only pair once.
- Surface Pens use AAAA batteries that typically last several months and can be replaced by opening the barrel at the bottom of the pen.
Turn on Bluetooth on your Surface device
Before your pen can find your device, Bluetooth must be active. On Windows, open the Settings app by pressing Windows key + I. Click Bluetooth & devices in the left sidebar, then toggle the Bluetooth switch to On. You'll see a blue toggle when it's active.
On a Mac, click the Apple menu in the top-left corner, select System Settings, then click Bluetooth in the sidebar. Toggle it on. If you're using an iPad, swipe down from the top-right corner to open Control Center and tap the Bluetooth icon to turn it on.
Leave this settings window open — you'll need to watch for your pen to appear in the list of available devices in the next step.
Put your Surface Pen into pairing mode
Hold your Surface Pen upright and locate the button at the very top of the barrel. Press and hold this button for three to five seconds. You should see the LED light on the side of the pen start to blink. This blinking means the pen is now in pairing mode and searching for your device.
If the light doesn't blink, the battery may be dead. Open the bottom of the pen barrel by twisting it counterclockwise and check that the AAAA battery is installed correctly, with the positive end facing up. Replace it if needed and try again.
Select the pen from your device's Bluetooth list
Look at the Bluetooth settings window you left open. Your Surface Pen should appear in the list of available devices within a few seconds. It will be labeled as "Surfacer Pen" or "Surface Pen" depending on which model you own. Click or tap on it to connect.
Your device will confirm the connection. The LED on the pen will stop blinking and stay solid, then turn off. This means pairing is complete. You can now close the Bluetooth settings window.
Test the pen and adjust pressure settings if needed
Open any app that accepts pen input — OneNote, Microsoft Word, or the built-in Paint app all work well. Touch the pen tip to your screen and draw a line. The pen should respond immediately without any lag. If it doesn't, go back to Bluetooth settings and make sure the connection shows as "Connected".
If you want to adjust how sensitive the pen is to pressure, open Settings and search for "Pen & Windows Ink". Click Pen & Windows Ink settings and you'll find sliders for pressure sensitivity and other pen behavior. These settings are optional — the defaults work fine for most people.
Reconnect the pen if it stops working
If your pen was paired before but suddenly stops responding, the Bluetooth connection may have dropped. First, make sure Bluetooth is still on in your device settings. Then press the top button of the pen once to wake it up. It should reconnect automatically within a few seconds.
If that doesn't work, go back to Bluetooth settings, find your Surface Pen in the list, and click the X or remove button next to it to unpair it. Then repeat the pairing steps above — press and hold the top button for three to five seconds and select it from the Bluetooth list again.
Replace the battery when the pen stops responding
Surface Pens use a single AAAA battery that lasts anywhere from a few months to over a year depending on how often you use the pen. When the battery runs low, the pen may become unresponsive or lag noticeably. You can replace it yourself in about 30 seconds.
Unscrew the bottom of the pen barrel by turning it counterclockwise. Slide out the old battery and insert a new AAAA battery with the positive end facing up. Screw the barrel back on clockwise. The pen should work immediately — no need to re-pair it.
Frequently Asked Questions
Do I have to pair my Surface Pen every time I use it?
No. Once paired, your pen stays connected to that device as long as Bluetooth is on. You only pair once. If Bluetooth is off, turn it back on and the pen will reconnect automatically within a few seconds.
Can I use the same Surface Pen with multiple devices?
Yes. You can pair the same pen to a Surface Pro, a Surface Laptop, and an iPad, for example. The pen will connect to whichever device has Bluetooth on. If both devices have Bluetooth on, the pen connects to the one it was most recently used with.
What if my pen won't show up in the Bluetooth list?
Make sure the battery isn't dead — open the barrel and check that the AAAA battery is installed correctly with the positive end up. Then press and hold the top button for a full five seconds. If it still doesn't appear, restart your device and try again.
Can I use a Surface Pen without Bluetooth?
No. All modern Surface Pens require Bluetooth to connect. Older Surface devices used to support pen input through other methods, but current Surface Pens are Bluetooth-only.
Does the pen work if my device's battery is low?
Yes, as long as your device is powered on. The pen's Bluetooth connection doesn't drain your device's battery significantly. However, if your device shuts down completely, the pen won't work until you turn it back on.
