MagyarDynabook Portégé A30-E laptop review: Great display, unstable case
Toshiba laptops are a thing of the past. Since April 1, 2019, new models of the well-known series Tecra, Satellite, Portégé, etc. have been operating under the brand name Dynabook. With the Dynabook Portégé A30-E, we now have a 13.3-inch business laptop that is the successor to the Toshiba Portégé A30-D. The two devices have little in common. The A30-E's competitors include well-known business laptops such as the Dell Latitude 5300, the HP ProBook 430 G6 and the Lenovo ThinkPad L390.

Case and connectivity - The A30 has a case made of plastic
Dynabook has opted for a matte black plastic housing for the Portégé A30-E. The top of the base unit and the back of the lid are provided with a grooved texture. The laptop is well processed. In terms of stability, we expect more. In this way, the base unit and the lid can be twisted too easily and too evidently. In addition, the base unit can be bent without any effort on both sides next to the keyboard. At the same time, the opposite front corner of the base unit is always raised above the surface. A laptop of this price range must offer more here. The battery is firmly installed - a difference from the predecessor.
In order to access the innards, the bottom cover must be removed. Only the SSD lacks direct access. It's mounted on the inaccessible side of the motherboard. To replace it, the motherboard would need to be dismounted.
The Type-C USB port (USB 3.2 Gen 2) supports both the DisplayPort via USB-C function and Power Delivery 3.0. A Type-A USB port (USB 3.2 Gen 1) is also available. This is complemented by an HDMI port and a Gigabit Ethernet port. A smart card reader is optionally available. While the previous model still had an optical drive, our current test device has none on board. It can't be retrofitted either. The new model also lacks the docking port of the A30-D.
The microSD memory card reader is one of the faster representatives of its kind. Copying large blocks of data achieves a maximum transfer rate of 82 MB/s. The transfer of 250 JPG image files (each of around 5 MB) is completed at a speed of 70 MB/s. We test the memory card reader using a reference card (Toshiba Exceria Pro M501 microSDXC 64GB).
The Wi-Fi module supports the fast ac standard. The transfer speeds measured under optimal conditions (no other Wi-Fi devices close by, short distance between laptop and server PC) are good. There's also an LTE modem on board.

Input devices - Key backlighting for the Portégé
Dynabook has equipped the A30 with a backlit chiclet keyboard. The flat, smooth keys provide a short travel and a clear pressure point. While typing, the keyboard gives in. The whole thing has a negative effect on the typing experience. The backlighting can be switched on and off through a function key. It's not possible to switch between the three available brightness levels by using the key. This is only possible within the "Dynabook Settings" software. All in all, Dynabook delivers a keyboard suitable for everyday use here; in terms of the laptop's price point, we would have expected something better. Users who do a lot of typing won't be happy with the keyboard.
The multitouch-capable ClickPad takes up an area of about 9.9 x 5.6 cm (~3.9 x 2.2 in). The smooth pad surface makes gliding easy for the fingers. It has a short travel and a clear pressure point. The laptop's fingerprint reader sits in the upper left corner of the pad.
Display - Dynabook computer with a bright IPS screen
The matte 13.3-inch screen of the A30-E works at a native resolution of 1920x1080 pixels. Contrast (1,538:1) and brightness (422.2 cd/m²) are good. Dynabook offers significantly more than the competition here.
The display flickers with a frequency of 250 Hz at brightness levels of 20% and below. Due to the low frequency, headaches and/or eye problems may occur in sensitive users.

Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 250 Hz | ≤ 20 % brightness setting |  |
The display backlight flickers at 250 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 20 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 250 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17933 (minimum: 5 - maximum: 3846000) Hz was measured. | |||
The display boasts a great color reproduction out of the box. With a DeltaE 2000 color deviation of 1.6, the target (DeltaE less than 3) is met. The grayscales are displayed in a quite balanced way. The display doesn't suffer from a blue tint. However, it isn't able to fully map the AdobeRGB (60%) and sRGB (96%) color spaces.
Dynabook has equipped the Portégé with an IPS panel that has stable viewing angles. Therefore, the screen can be read from any position. Thanks to its high brightness, this is also possible outdoors - as long as the sun doesn't shine too brightly.
Performance - Core i7 with restrained Turbo
With the Portégé A30-E, Dynabook delivers a business laptop in the 13.3-inch format. The device provides enough computing power for office and Internet applications. Our test device is available from around 1,300 Euros (~$ 1,445) and is therefore the most expensive model in the series at the moment. Other configuration variants are available.
Processor
The Portégé is powered by an Intel Core i7-8550U (Kaby Lake refresh) quad-core processor. The CPU operates at a base speed of 1.8 GHz. An increase to up to 4 GHz is possible through Turbo.
The processor works through the multithread tests of the Cinebench benchmarks at 3.1 to 3.2 GHz for a few seconds. The clock speed then drops to 2.1 to 2.3 GHz. The single-thread tests are run at 3.2 to 4 GHz for a short time. The clock speed then drops to 2.9 to 3.8 GHz. On battery power, the speeds range from 1.7 to 1.9 GHz (multithread) and 1.6 to 2.5 GHz (single-thread), respectively.
We test whether Turbo is also used consistently by running Cinebench's R15 multithread test continuously in a loop for a about 30 minutes. The results fall slightly from the first to the second run and then remain at a constant level. Turbo is used to a very small extent.

Gaming performance
The hardware of the A30-E allows playing some of the games that are in our database smoothly - at low resolutions and low quality settings. This includes games that only have moderate hardware requirements - such as "Bioshock Infinite" or "League of Legends". The titles of the last three or four years are unplayable for the most part.

Noise emissions
When idle, the fan is often turned off and silence prevails. It turns up under full load. During the stress test, we measure a sound pressure level of 38.8 dB(A). The fan produces a subtle whistle, which can be tolerated for a short time. Over a prolonged period of time, it quickly becomes annoying.

Temperature
Our stress test (Prime95 and FurMark run for at least an hour) is run by the processor and graphics core at 1.4 GHz and 200 MHz, respectively. On battery power, the clock speeds range from 800 to 900 MHz (CPU) and 650 MHz (GPU), respectively. The stress test represents an extreme scenario that doesn't occur in everyday life. With this test, we verify that the system remains stable even under full load.
The Toshiba Portégé doesn't get excessively warm. During the stress test, we only register a temperature just above 40 °C (~104 °F) at one measuring point. In everyday operation, the values are significantly lower.
(+) The maximum temperature on the upper side is 36.3 °C / 97 F, compared to the average of 35.9 °C / 97 F, ranging from 21.4 to 59 °C for the class Subnotebook.
(±) The bottom heats up to a maximum of 40.8 °C / 105 F, compared to the average of 39.4 °C / 103 F
(+) In idle usage, the average temperature for the upper side is 25.3 °C / 78 F, compared to the device average of 30.7 °C / 87 F.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 24.3 °C / 75.7 F and are therefore cool to the touch.
(+) The average temperature of the palmrest area of similar devices was 28.3 °C / 82.9 F (+4 °C / 7.2 F).
Speakers
The stereo speakers of the Dynabook laptop are placed at the front edge of the device's bottom. They produce a decent sound that is largely lacking bass.

Battery life
Our practical Wi-Fi test uses a script to simulate the load caused by accessing websites. The "Balanced" profile is active, the power saving functions are deactivated, and the display brightness is adjusted to about 150 cd/m². The Portégé reaches a runtime of 10:35 h.
Pros
Cons
Verdict
The big highlight of the Portégé A30-E is the display. This is a bright, contrast-rich, viewing-angle-stable IPS model that offers great color reproduction. The sRGB color space can be mapped to 96%.
