Microsoft is hard at work on a new flagship laptop, which Windows Central understands could show up as soon as this fall. Many expect this new laptop to replace the Surface Book, which has been Microsoft’s flagship laptop line since its debut in 2015.

Windows Central understands that this new laptop likely won’t be branded as “Surface Book,” but rather something possibly under the “Surface Laptop” moniker such as “Surface Laptop Pro” or “Surface Laptop Studio.” That said, because we don’t actually know what it will be called, we figured calling it Surface Book 4 makes the most sense for now.

With that in mind, let’s dive into what we do and don’t know so far.

Surface Book 4: Release date and availability

Microsoft has not yet announced that new hardware is coming, so we don’t have an official date for release or availability. That said, Microsoft always holds a hardware event in the fall, usually in October, and we hear that the same will be happening this year.

Assuming the device is announced in October, the Surface Book 4 likely won’t begin shipping until late October in some markets, and in the months following in other markets. Because of the global chip shortage, it’s unknown what markets the Surface Book 4 will be available in outside the United States.

Microsoft is expected to announce a handful of other devices in October too, including the Surface Duo 2 and Surface Pro 8.

Surface Book 4: What to expect

Details around the Surface Book 4 are scarce, but a recent patent filing may have already given us a first look at its design. Windows Central understands that the new Surface Book has a new design, one that no longer has a detachable display. This patent filing shows a display that can instead be pulled forward, similar to the Surface Studio.

A non-detachable design may allow Microsoft to put in more powerful chips too. The Surface Book’s existing design only allows for U-series processors at most, which maxes out at just 4 cores. Most power-user grade laptops have options for 6-core or even 8-core processors like Dell’s 15 and 17-inch XPS laptops. So we wouldn’t be surprised to see options for more powerful chips inside this new laptop design.

We also hear that the Surface Book 4 will feature RTX graphics, a larger trackpad, and a display size of around 14 inches with a high-refresh rate pane that dynamically adjusts.

  • Redesigned: A pull forward display instead of one that can detach.
  • New display: Around 14 inches in size with a dynamic high-refresh rate.
  • RTX graphics: Powerful mobile graphics from NVIDIAs RTX line.

The Surface Book 4 will also be one of the first devices to ship with Windows 11, which includes a handful of new features that could benefit from new hardware, such as:

  • Dynamic Refresh Rate: This feature would enable a higher-refresh display like 90Hz or 120Hz, but can still drop to as low as 60hz when nothing is moving on the display. This can help save a bit of battery when running a higher-refresh rate display.

  • New Haptic Surface Pen: Windows 11 also supports smart pens with haptic feedback, which lets the pen simulate writing with different materials like pencil or pen on different types of paper. It’s likely that Surface Book 4 will feature support for a new Surface pen with haptics.

Surface Book 4: Specs

Surface Book 4: Price

Pricing for the Surface Book 4 is unknown at this time. Considering it will likely be positioned as a more powerful and versatile Surface Laptop, it’s possible that we could see prices start at around the same as a Surface Book 3 at $1,599. That said, we just don’t know how Microsoft plans to price this device, as it will likely be considered a new form factor with a new design and limited availability at first.

As this device will feature a new design, there’s room for new additions that previous Surface’s haven’t included. Here’s what I personally hope to see in the Surface Book 4:

  • Thinner bezels: Since the Surface Book 4 as a new display size, Microsoft could (and should) take this opportunity to slim the bezels around the display.
  • Thunderbolt 4: Microsoft’s Surface line has always missed out on Thunderbolt, which is quickly becoming a pain point for many professional users. Microsoft should figure out a way of adding Thunderbolt 4 without removing the Surface Connect port.
  • Display tech enhancements: While our sources suggest Surface Book 4 will have a higher-refresh rate display, we still don’t know what kind of display panel it will have. We’d love to see options for an OLED panel, or options for an anti-reflective coating that helps diffuse light. Also, rounded display corners would be nice.
  • Better upgradability: Microsoft has made small waves in making Surface products more upgradable, and we’d love to see that continue on Surface Book 4. Adding a removable SSD would be a great start.
