――Ease of use check ――

▶ Keyboard

▲ Tap or click to enlarge

It has a keystroke of 1.5 mm and has a good typing feel.

The key pitch (the distance between keys) is about 19 mm, which is said to be easy to type.
* There is no 19mm key pitch for some small keys.

Key pitch

▼ The hyphen key is small, so I wish it had the same size as the other character keys.

The typing sound is a little quiet.

For the function keys (F1 to F12 keys), the default functions of Windows such as full-width katakana conversion are prioritized.

(To use the unique functions assigned to the F key, such as raising or lowering the brightness of the display, press the Fn key at the same time.)

▼ It is not a big dent because it is a 0.2 mm dent, but it is difficult for the force of your fingertips to escape because there is a dent on the key top.

Key top up image

▲ The key top is exposed to light to create a dented line.

Keyboard up from diagonally above

The keyboard backlight is not installed.

▼ The palm rest is not cramped.

Place your hand on the palm rest

Touchpad

A fingerprint sensor is mounted on the upper left of the touchpad.

Touchpad

The clicking sound when you press the touchpad is about normal.

In addition, it should be notedIt is convenient because you can switch the touchpad disabled / enabled with the Fn + F9 keys.

▶ Speaker

A speaker is mounted on the bottom of the front side.

dynabook SZ73 / P speaker

I felt that the sound quality of the speakers was “I want a little more sound omission.” I think the sound quality is high enough to enjoy music while working.

▶ Display

The dynabook SZ series is equipped with Sharp’s IGZO liquid crystal.doing.
* IGZO liquid crystal is only for models with full HD image quality.

It is an easy-to-see display that does not get too dark even when viewed at an angle.

Viewing angle check Viewed from the side

Color gamut

Color gamut

■ Cover rate

sRGB 99%
Adobe RGB 74%

* The values ​​are measured by us only, so there may be differences depending on the environment and measuring equipment.

As a liquid crystal display, it covers a wide color gamut.

Since it is a non-glare liquid crystal, it is difficult to be reflected.

The display of the dynabook SZ series isSince it is a non-glare (non-glossy) liquid crystal, it is difficult to reflect.

How the light is reflected on the display

Light is reflected during work and it is hard to flicker, soEasy on the eyes and practicalis.

▼ I tried to open the display. It will open up to this point.

▶ Battery life

■ Actual measurement of battery drive time

JEITA Ver.2.0 About 19 hours
* Manufacturer announced value
Used for browsing the internet and typing text
(Load: Light)
10 hours 15 minutes
PCMark 8 WORK
(Load: Medium)
6 hours 16 minutes
* Time until the battery level drops below 20%
Amount of battery that could be charged in 30 minutes About 43%

* Display brightness: Measured at 80%. The darker the display, the longer the battery life.

Tap (click) here to see the measurement conditions, etc.

■ Battery drive time measurement conditions for “used for browsing the Internet and typing text”

  • Display brightness:80%
  • Battery saving function: Turns on with 20% or less battery remaining
  • Web browsing: Open 5 tabs in your web browser and display the website in each tab. Each of those tabs is automatically reloaded every minute.
  • typing: Using software called BBench, typing input is automatically performed every 10 seconds.
  • In the above state, measure from 100% battery level.

■ About “PCMark 8 WORK”

It is a measurement test of the battery drive time with the software “PCMark 8”.
It also includes operational tests that have a significant impact on battery life, such as viewing 3D images on websites and video chatting.

When actually used at 80% brightness of the display, it seems difficult to use for 19 hours, but it was a relatively long battery life.

▶Quiet

I tried to see how noisy it would be when it was loaded.

Measured from a distance of 30 cm in height and 30 cm in depth from the hinge, taking into consideration the position of the ears during use.

When idle Almost silent
* You can hardly hear the operation sound even if you bring your ears closer.
Benchmark test Around 43db

Even if the fans are full and do their best, the impression is that the sound is not so loud.

You can use it in a quiet place such as a library without worrying about your surroundings.

■ Estimated noise (number of decibels)

Pretty noisy 70db In a noisy office
Noisy 60db Ordinary conversation in a moving car
ordinary 50db Quiet office
quiet 40db Quiet residential area, library
Very quiet 30db Midnight suburbs
Almost inaudible 20db The sound of snow

* The table is just a guide.

▶ Size

It is a size comparison with a semi-B5 notebook (university notebook).

Comparison of A4 paper and SZ73 / P size

Thinness of SZ73 / P

University notebook 252 × 179mm
A4 size 297 × 210mm
dynabook SZ series 316 x 227 mm (x thickness 19.9 mm (excluding protrusions))

The width x depth is a little larger than the A4 size, so it is easy to carry even a standard size business bag.

I put it in my business bag

Where to hold it aside

▶ Actual weight: 1171 grams

Where you have it lightly

Where we are measuring the weight

Body About 1,171g
AC adapter + power cable About 179g

It’s a little lighter for a 13.3-inch laptop.

As checked above, the battery life was about 10 hours if the load was light, so
For a little business, you don’t have to carry the AC adapter with you.

▶ Interface

■Right side

Right side

① USB 3.0
② LAN connector
③ Security lock slot

■Left side

Left side

① Power connector
② USB Type-C
③ HDMI output terminal
④ Microphone / headphone output terminal
⑤ microSD card slot

For those who want to connect to the Internet by wire, it’s nice to have a LAN connector.

▼ Even if you insert the microSD card, it will not stick out, so it will not get in the way even if you leave it inserted.

By the way, I connected an external monitor to the “USB Type-C terminal” and “HDMI terminal” to make a triple display (two external displays).

Charging from mobile battery

Charging with a mobile battery

I connected the mobile battery to the USB Type-C terminal and was able to charge the SZ73 / P side.

* By the way, this time I charged from a mobile battery with 45W output, but it is unconfirmed how much output mobile battery can be charged.

――Checking processing performance ――

▶CPU performance

The CPU of this review machine is“Intel Core i5-8250U processor (4 cores 8 threads, 1.6-3.4GHz)”is.

CPUMark

PassMark CPU Benchmark Test Results: 6257

Average value of the same CPU in PassMark 6078Because it is a higher number than, the CPU performance is good.
* Average value as of September 23, 2020

CINEBENCH R20

  CINEBENCH R20 test results

Multi-core 1107
Single core 332

For business use, it has a margin of performance.

The CPU installed in the dynabook SZ series differs depending on the model number.

For business use, I think that the model with Core i3 is enough,

If you want to multitask with plenty of time, or if you want to do simple image editing, we recommend the Core i5 or Core i7 equipped model.

▶ SSD data transfer speed

Storage transfer rate

Since it is an SSD with SATA connection, the data transfer speed is not particularly fast as an SSD, but it is overwhelmingly faster than HDD.

By the way, the dynabook SZ series has a lineup from the model with SSD capacity of 128GB,If it is 128GB, there is not much room in the capacity

Since the capacity is taken up by the OS etc., you can actually use about 80GB by yourself.

“I rarely install software and don’t save much data.”

If so, I think 128GB is enough, butIf you use it as a main PC, SSD capacity 256GB or more is recommendedis.

SSD Information

* Laptops of the same model number may be equipped with SSDs from different manufacturers.

▶ Graphics performance

■ Graphics of dynabook SZ73 / P

Model with Core i3 Intel HD Graphics 620
Models with Core i5 / i7 Intel UHD Graphics 620

The review machine this time is “Core i5 equipped model: Intel UHD Graphics 620”.

3DMark score
Fire Strike 960
Time Spy 398
Dragon Quest X Benchmark
Standard quality (1920×1080) 3752 ordinary
FF14 Jet Black Villas Benchmark
Standard quality(1920×1080) 1515 Recommended to change settings

* Graphics settings are measured with settings for “notebook PCs”.

Can I play 3D games with a light load such as Dragon Quest X? The graphics performance is about the same, but the graphics performance is not very high.

Appearance of dynabook SZ73 / P

The dynabook SZ seriesA well-balanced laptop with a light body, high robustness, and long battery lifeis.

There is also a dynabook GZ series as a lighter model, but the SZ series is cheaperis.

* As I wrote in the beginning, if you register as a member from the dynabook online store, the price will be cheaper.

  • Emphasis on “price” and “robustness”: SZ series

It is a place like that.
