The Microsoft Surface Book 2 remains one of the more distinctive Windows laptops Microsoft has produced, thanks to its detachable display, premium magnesium body, and unusually powerful hardware for a 2 in 1 device. One common question from buyers, owners, and refurbished laptop shoppers is simple: does the Surface Book 2 have a backlit keyboard? The short answer is yes, but there are a few details worth understanding about how it works, how to adjust it, and what to check if the keyboard lighting does not appear to turn on.
TLDR: Yes, the Surface Book 2 has a backlit keyboard. The keyboard backlight can be adjusted using the keyboard brightness key, and it supports multiple brightness levels. If the backlight is not working, the cause is usually a settings issue, low ambient visibility, a firmware or driver problem, or a hardware fault in the keyboard base.
Does the Surface Book 2 Have a Backlit Keyboard?
Yes, the Surface Book 2 does include a backlit keyboard. This applies to both the 13.5 inch and 15 inch Surface Book 2 models. Microsoft designed the Surface Book 2 as a premium productivity laptop, and keyboard backlighting was included as part of that premium experience.
The backlight is built into the keyboard base, not the tablet portion of the device. This distinction matters because the Surface Book 2 has a detachable screen. When the display is detached and used as a tablet, there is obviously no physical keyboard connected unless you reattach it to the base. The keyboard lighting only functions when the screen is properly connected to the keyboard base and the device is powered on.
For users who type in dim lighting, such as on airplanes, in lecture halls, at night, or in shared offices, the backlit keyboard is a practical feature. It makes the key legends easier to see without requiring a separate desk lamp or increasing screen brightness excessively.

The Surface Book 2 keyboard backlight is controlled directly from the keyboard. Microsoft uses a dedicated key to cycle through brightness levels. On most Surface Book 2 keyboards, the backlight control is located on the top function row and is marked with a small keyboard or illumination icon.
Pressing this key cycles the keyboard through several states, typically including:
- Off: The keyboard illumination is disabled.
- Low brightness: Keys are softly illuminated for dark environments.
- Medium brightness: A balanced level for general low light use.
- High brightness: Maximum illumination for very dark surroundings.
The exact visual effect may vary slightly depending on the keyboard layout, region, and age of the device, but the basic function is the same. The backlight is intended to be subtle, not flashy. It is white rather than multicolor, and it is designed for readability rather than decorative lighting.
How to Turn On the Surface Book 2 Keyboard Backlight
To turn on the keyboard backlight, make sure the Surface Book 2 is awake and the display is securely attached to the keyboard base. Then press the keyboard backlight key on the function row. If the backlight is currently off, one press should usually turn it on at a low brightness level. Pressing it again will increase the brightness, and pressing through the cycle will eventually turn it off again.
If your function keys are locked in a particular mode, you may need to use the Fn key along with the keyboard backlight key. Surface keyboards can behave differently depending on whether the function row is set to standard function key behavior or special shortcut behavior.
Try the following steps:
- Wake the Surface Book 2 and sign in to Windows.
- Confirm the display is firmly connected to the keyboard base.
- Press the keyboard backlight key once.
- If nothing happens, press Fn and the keyboard backlight key together.
- Repeat the key press several times to cycle through brightness levels.
In a bright room, the backlight may be difficult to see. If you are testing whether it works, move to a dim room or cover part of the keyboard with your hand while pressing the backlight key.
Does the Backlight Turn On Automatically?
The Surface Book 2 may appear to manage keyboard illumination intelligently, but users should not rely on it behaving exactly like every other laptop. In practice, the safest assumption is that the keyboard backlight is manually controlled through the keyboard shortcut. Some Windows power states, sleep behavior, and firmware conditions may affect whether the backlight returns to its previous setting after waking.
If you previously set the keyboard to a certain brightness level, it may remember that preference after sleep or restart. However, if the battery is very low, the system has recently updated, or the keyboard base has been detached, the behavior may change. This does not necessarily indicate a fault.
Why the Backlit Keyboard Matters
A backlit keyboard may seem like a small feature, but on a productivity focused laptop it can make a significant difference. The Surface Book 2 was built for professionals, students, designers, developers, and mobile workers. Many of those users work outside ideal lighting conditions.
The main benefits include:
- Improved visibility: You can identify keys more easily in dark rooms.
- Better productivity: Less time is spent correcting typing mistakes caused by poor visibility.
- Lower eye strain: You do not need to increase the display brightness just to see the keyboard.
- Professional usability: It is helpful in meetings, presentations, classrooms, and travel settings.
For many people buying a used or refurbished Surface Book 2, the presence of keyboard backlighting is an important confirmation that the device still meets modern laptop expectations.
What If the Surface Book 2 Keyboard Backlight Is Not Working?
If your Surface Book 2 keyboard backlight does not turn on, do not immediately assume the hardware is broken. Several common issues can prevent the lighting from appearing to work. Start with the simplest checks before considering repair.
1. Check the Brightness Cycle
The keyboard backlight may simply be set to off. Press the backlight key several times, waiting a moment between presses. Because the key cycles through multiple brightness levels, a single press may not always produce the result you expect.
2. Use the Fn Key
If the top row is acting as standard function keys, the backlight shortcut may require the Fn key. Try pressing Fn plus the backlight key. You can also toggle the Fn lock depending on your keyboard behavior.
3. Test in a Darker Environment
In daylight or under strong office lighting, the white backlight can be hard to notice. Turn off nearby lights or test it at night. Look closely around the edges of the keys and the symbols on the keycaps.
4. Reattach the Display
Because the Surface Book 2 uses a detachable design, the connection between the tablet and keyboard base is critical. Detach the display properly using the detach key or Windows detach option, then reconnect it firmly. Listen for the attachment sound and check that Windows recognizes the base.
5. Restart the Device
A restart can resolve temporary Windows or firmware glitches. Shut the Surface Book 2 down completely, wait a few seconds, and turn it back on. After signing in, try the keyboard backlight key again.
6. Install Surface Updates
Microsoft has released firmware and driver updates for Surface devices over time. These updates can affect keyboard, base, battery, and device communication behavior. Go to Settings, then Windows Update, and install available updates. After updating, restart the device and test the backlight again.
7. Check for Hardware Damage
If the keyboard itself works but the backlight never turns on, the lighting circuit may be damaged. Liquid spills, drops, worn connectors, or internal base faults can affect the backlight. If some keys illuminate and others do not, that is more likely to indicate a hardware problem than a settings issue.
Is the Surface Book 2 Keyboard Comfortable to Use?
The Surface Book 2 keyboard is generally regarded as one of the stronger parts of the device. It has a stable deck, well spaced keys, and a typing feel suitable for long writing sessions. The backlight complements this by making the keyboard easier to use in varied lighting conditions.
The key travel is more traditional than on many ultra thin laptops, which can be helpful for users who type heavily. The touchpad is also glass and supports Windows precision gestures. While the Surface Book 2 is older by current standards, its keyboard experience still compares favorably with many modern premium laptops.
Does Every Surface Book 2 Configuration Have the Same Keyboard Backlight?
In general, Surface Book 2 models include keyboard backlighting regardless of whether they are 13.5 inch or 15 inch versions. However, used and refurbished devices require careful inspection. A previous owner may have replaced parts, damaged the base, or sold the tablet portion with a mismatched or faulty keyboard base.
If you are buying second hand, verify the following before purchase:
- The keyboard base is included and properly attaches to the display.
- The keys work normally in a text field or keyboard tester.
- The backlight cycles through brightness levels using the proper key.
- The detach mechanism works without error messages.
- The battery in the base is detected by Windows, if applicable.
These checks are especially important because the Surface Book 2 is no longer a new device. Age and usage history can affect reliability.
Does the Surface Book 2 Backlit Keyboard Drain Battery?
Yes, any keyboard backlight uses some battery power, but the impact is usually modest. The Surface Book 2 has batteries in both the display and the keyboard base, and the keyboard lighting consumes far less power than the display, processor, graphics chip, or active wireless connections.
Still, if you are trying to maximize battery life, it is sensible to reduce the keyboard backlight brightness or turn it off when you do not need it. This is particularly useful during travel, extended note taking, or situations where charging is not available.
Surface Book 2 Compared With Other Surface Keyboards
Microsoft has included backlit keyboards on many premium Surface devices, including Surface Laptop models and Surface Pro Type Covers. The Surface Book 2 fits within that same premium category. Its keyboard is not merely an accessory in the usual sense; it is part of the laptop base and contributes to the full notebook experience.
Compared with detachable Type Covers, the Surface Book 2 keyboard base feels more rigid and laptop like. This helps the backlight feel more integrated and consistent. The main limitation is that if the base develops a fault, the keyboard and its illumination are tied to that base hardware.
Final Verdict
The Surface Book 2 does have a backlit keyboard, and it supports adjustable brightness levels. For most users, turning it on is as simple as pressing the keyboard backlight key on the function row. If it does not appear to work, test it in a dark room, try the Fn key combination, restart the device, reattach the display, and install available Surface updates.
For anyone considering a used Surface Book 2, the backlit keyboard is a standard feature worth testing before purchase. A working backlight confirms not only convenience in low light but also that the keyboard base is functioning properly. While the Surface Book 2 is no longer Microsoft’s newest hardware, its illuminated keyboard remains a useful and professional feature that supports comfortable typing in real world conditions.
