Asus Googlebook 14 Laptop Review - An ExpertBook Ultra with a Glowbar

Sub 1 kg & a matte OLED.

The Asus Googlebook 14 uses the chassis from the high-end ExpertBook Ultra in combination with a matte OLED touchscreen. The result is a sub 1 kg everyday laptop with plenty of ports, but it is also very expensive with a base price of $1299 considering the limitations of Googlebook OS.

Verdict - Good hardware, limited software

The Asus Googlebook 14 feels like a premium business laptop, and considering it is based on the excellent ExpertBook Ultra, this is hardly a surprise. You get a high-quality and lightweight chassis (under 1 kg), even though it might actually feel a bit too light and therefore not premium for some users. The typing experience is also slightly affected by that, even though the key travel and the precision are very satisfying. Thanks to the Intel CPU, you get sufficient performance, Thunderbolt 4 connectivity and also regular USB-A ports as well as Wi-Fi 7. Battery runtimes are still okay (even though below average) and it is very quiet most of the time.

Right now there are still some issues with the software, though. Not all Android apps are working, we were not able to use the extended features with a modern Android 17 smartphone (handoff, app sharing) and the screen behavior is a bit strange as it looks more like an IPS panel with the increased black value and the limitation to the sRGB gamut. Color accuracy is not great, either, so picture editing is not recommended.

Considering the low TDP and the limitation to Android apps, it makes absolutely no sense to get the SKU with the faster Core Ultra 7 355, which is about $300 more expensive than the Core Ultra 5 325 SKU with the same amount of RAM/SSD. 

All in all, you get a very lightweight companion for everyday tasks within the Android ecosystem, but Googlebook OS is limited and it is a shame that there is no integrated 5G connectivity.

Pros

+ lightweight and premium chassis
+ matte OLED screen with 120 Hz
+ excellent sound system
+ Thunderbolt 4, USB-A & Wi-Fi 7
+ good input devices
+ always silent or very quiet

Cons

- PWM flickering
- soldered RAM
- screen calibration is off
- limitation to Android apps (some are not compatible)
- no 5G/LTE connectivity

Case, Connectivity and Input Devices

The Asus Googlebook uses the chassis from the Expertbook Ultra, but in dark anthracite color. It looks great (even though we are not sure about the glowbar on the lid) and fingerprints are actually not a huge problem. Both stability and build quality are also great and it only weighs 967 grams. However, this can also slightly affect the quality impression, as it might already be too light for some users. The typing experience (1.5 mm travel, fingerprint reader in the power button) is also slightly affected by the low weight and is a bit on the loud side, but still works very well overall, just like the haptic trackpad. Maintenance is limited to the fan, the battery and the M.2-2280 SSD.

You get Wi-Fi 7 and plenty of ports including Thunderbolt 4, regular USB-A ports as well as HDMI. However, there is no 5G connectivity and the 1080p webcam (with mechanical shutter) only takes average pictures.

Display - Matte OLED touchscreen with 120 Hz

Subpixel array
Subpixel array

Asus uses a 14-inch matte OLED touchscreen with 2880 x 1800 pixels and 120 Hz. However, there seem to be some software quirks with Googlebooks OS and the measurements in our analysis with the professional CalMAN software do not meet our expectations. The subjective image quality is good and while bright contents appear slightly grainy due to the matte coating, it is much better in bright environments due to reduced reflections. One issue is the increased black value, so the contrast is lower than you would expect from an OLED panel.

Our measurements show a maximum SDR brightness of more than 500 nits and HDR contents are also supported with a peak brightness of 1266 nits. HDR handling also seems to work fine and the panel simply uses higher brightness levels when HDR contents are shown (similar to macOS). Color calibration is completely off, however, and the Asus Googlebook OS is running in sRGB mode. We hope this will be fixed via software update.

Display Response Times

ℹ
Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
   ↔    Response Time Black to White
0.44 ms ... rise ↗ and fall ↘ combined↗ 0.24 ms rise
↘ 0.2 ms fall
The screen shows very fast response rates in our tests and should be very well suited for fast-paced gaming.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 1 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (19.6 ms).
   ↔    Response Time 50% Grey to 80% Grey
2.6 ms ... rise ↗ and fall ↘ combined↗ 1.3 ms rise
↘ 1.3 ms fall
The screen shows very fast response rates in our tests and should be very well suited for fast-paced gaming.
In comparison, all tested devices range from 0.13 (minimum) to 636 (maximum) ms. » 13 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (30.7 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

ℹ
To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM detected 720 Hz
Amplitude: 44 %
≤ 99 % brightness setting

The display backlight flickers at 720 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 99 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 720 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 7594 (minimum: 5 - maximum: 343500) Hz was measured.

Performance - Intel Panther Lake

The Asus Googlebook 14 is equipped with the Intel Core Ultra 7 355 and based on our power measurements, the TDP should be 45 Watts for a couple of seconds and then around 18 Watts for sustained workloads. It therefore does not make sense to pay the additional price over the Core Ultra 5 325 SKU. The overall performance with 16 GB RAM and 512 GB storage is sufficient and the Googlebook 14 is a snappy system overall. We performed some benchmarks (see list below), but the tests are limited on Android and some benchmarks are not supported by Googlebook OS (like CrossMark). This is also the case for some popular games like PUBG or Fortnite.

Asus only uses one fan for the Googlebook 14 and that is more than sufficient. The laptop is usually silent and you can only hear a slight fan murmur when you really stress it. We did not hear any other electronic noises, either.

Power Consumption and Battery Life

Battery information
Battery information

The Googlebook 14 is very efficient while idling, but also benefits from the dark default wallpaper. When you use a brighter image, the OLED will also consume more power. Under load, we measured up to 66 Watts for a few seconds, but the consumption quickly dropped to just 27 Watts. 

The runtime with the 70 Wh battery is below average at around 13 hours in our Wi-Fi test at 150 nits and around 8 hours at full brightness.

The selection of devices to be reviewed is made by our editorial team. The test sample was provided to the author as a loan by the manufacturer or retailer for the purpose of this review. The lender had no influence on this review, nor did the manufacturer receive a copy of this review before publication. There was no obligation to publish this review. As an independent media company, Notebookcheck is not subjected to the authority of manufacturers, retailers or publishers.

This is how Notebookcheck is testing

Every year, Notebookcheck independently reviews hundreds of laptops and smartphones using standardized procedures to ensure that all results are comparable. We have continuously developed our test methods for around 20 years and set industry standards in the process. In our test labs, high-quality measuring equipment is utilized by experienced technicians and editors. These tests involve a multi-stage validation process. Our complex rating system is based on hundreds of well-founded measurements and benchmarks, which maintains objectivity. Further information on our test methods can be found here.
