How to download drivers for surface pen (manually)

Before starting manually downloading the necessary drivers for your Surface Pen, you have to check if your device needs an update. If so, start by updating.

To check for updates go to Start>Settings>Updates & Security. Here you can check if you have already downloaded the most recent updates. If you need to update, then do it and restart the device.

You may wonder why you would want to download the drivers manually. Well, you might use this method because your device is offline. 

So, next you have to install the battery by unscrewing the top of the pen and insert an AAAA battery. The positive end of the battery should point to the tip of your pen. Then, when you screw the top back on the pen, pair it with your device.

Go to the official page of Surface’s Download Center page and navigate to find your Surface model from the and click the link for the latest display, sound, ethernet, Wi-Fi firmware and drivers.

How to use the Surface Diagnostic Toolkit to check the surface pen battery

Unfortunately, the Toolkit can’t help you check the battery level (and health) of your Surface Pen. The Surface Diagnostic Toolkit is very useful to check and troubleshoot your 2-in-1 touch screen laptops (Surface device). 

On the flip side, checking your pen’s battery is totally doable via the Surface Pen app.

Alternatively, if your Surface Pen is connected to your Surface, you can check its battery without the app as well. All you have to do is go to Start > Settings > Devices > Bluetooth and Other Devices. From there, you can see the current battery level on your Surface Pen.

Alternatives to the Surface Pro Pen (for Surface Pro laptops) 

There are quite a few alternatives to the Surface Pro Pen. Since the Surface Pro 7, 8, X are Windows based, there are many digital pens by third party manufacturers that mimic the official pen.

See our full post on Surface Pro Pen alternatives for in depth details.

The benefit to using a different pen other than the official stylus pen from Microsoft is the price point, however if you’re looking for quality, the official pen can’t be beat. This is because it was designed by Microsoft themselves to integrate smoothly with the laptop.

Take the Apple Pencil on the iPad for example, alternatives exist, but aren’t always as easy to set up, or provide the seamless integration the same way Apple provides with their stylus.  Some examples of alternatives are the Renaissance, Wacom Bamboo Ink, Tesha Stylus, and Adonit Stylus models.


How do I find a lost surface pen?

If you ever lose your Surface Pen you can use the “Where is my Pen” feature to detect the last location of it and find it. 

Even though it’s not possible to know the current location of your lost pen, your Surface device can tell you where the last location that you were using it. This is happening because the Surface pens don’t include GPS.

You can use the Settings app of your device to do so. First you have to enable it. Go to Start>Settings>Updates & Security>Find my device. Click the Change button and turn on the Save my device’s location periodically toggle switch. 

Now, if you lose your pen follow these steps:

  1. Go to Start>Settings
  2. Update & Security
  3. Press Find my device
  4. Under the section Where is my Pen? Select the Go here to track it link.

Then it will open a map and let you know the last location that your Surface device was seen. It will give you the approximate location of the pen.

How do I fix a surface pen tip not working

If you feel that your Surface Pen tip needs to be changed then all you have to do is use the Microsoft Surface Pen Tip Kit or an alternative tip kit. The official Surface Pen kit includes 4 tips that are specially created to fit on your Surface Pen.

To change the tip, all you need to do is use the built-in extractor tool. Simply swap the tip by holding the tip that is currently in the Pen and pulling it out. Then, replace it with one of the other tips in the Kit.

The tips that come with the Pen Tip Kit mimic standards typically found on real pencils.  The standard tip that comes with the Surface Pen for Surface Pro 4 is HB, which is the standard hardness found in most pencils and provides you medium hardness. The Pen Tip Kit also comes with 2H, H, and B.

The replaceable tips make the Surface Pen better than the latest Apple Pencil in terms of flexibility, as Apple’s stylus doesn’t allow you to change the tip.

Here’s how to swap out your pen tips:

  1. Use something to pull and slide out the pen tip, like tweezers
  2. Pull until the entire tip of your Surface Pen is removed
  3. Insert the thinnest part of the replacement pen tip into your Surface Pen
  4. Push down on the tip until it clicks into place


In this article, we found out that changing the battery for Surface Pro Pen is totally doable. If you find your Surface pen not working, it is probably because of the battery (either its dead or faulty). 

Thankfully, you can easily change your Surface Pro X or Surface Pro 7 pen battery just by following a few easy steps. The same is true for the Surface Pro 3 stylus and any official pen that connects to the Surface Go 2. 

All you have to do is turn off Surface Pen, twist the top of your pen, pull the old batteries off and replace them with new AAAA batteries. 

This blog post also helped you find out how to connect Surface Pen to your PC and use the stylus for drawing apps like AutoCad and Final Cut Pro (as well as photo editing apps like adobe Photoshop & illustrator).

Keep in mind that Microsoft includes a comprehensive Surface Pro Pen instructions manual that you can use at any time you have a problem.
