案例
机箱是对老款Portege X40-G的全面修订。它的边框在所有方面都更窄，而沿着后角的两个大的灰色铰链现在已经消失，转而采用条形铰链。盖子的边缘和角落现在也是铬合金切割。
对于一台14英寸的商务笔记本电脑来说，尺寸是平均水平。这款 ThinkPad X1 Carbon相比之下明显更轻，但也更贵。
连接性
有很多端口可供选择，包括四个USB端口（2个USB-C + 2个USB-A），并支持Thunderbolt 4。我们的主要抱怨在于端口的定位，因为它们被紧密地挤在一起。较厚的USB设备或HDMI线可能会因此而妨碍相邻的端口。

配件和保修
除了用户手册和文件外，盒子里没有任何额外的东西。从好的方面看，这是为数不多的经济型办公笔记本电脑之一，标配3年有限制造商保修。
输入设备
显示
我们的设备配备了类似于Vaio FE14上的Chi Mei面板。 Vaio FE14(N140HCA-EAC对N140HCA-EAD)。因此，这两块经济型面板具有相似的属性，包括有限的65%sRGB覆盖空间，但我们的Dynabook显示器似乎具有较弱的黑色水平，对比度较浅。

该显示器开箱后没有得到很好的校准。用X-Rite色度计自行校准显示器将大大改善平均DeltaE值，正如我们下面的CalMAN屏幕截图所示。尽管如此，由于上述狭窄的色彩空间，一些颜色在较高的饱和度水平上仍然非常不准确。尤其是品红和蓝色，几乎没有像其他原色和次要颜色那样准确。
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 | ||
|---|---|---|
| 20.4 ms ... rise ↗ and fall ↘ combined | ↗ 12 ms rise |  |
| ↘ 9.2 ms fall | ||
| The screen shows good response rates in our tests, but may be too slow for competitive gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 42 % of all devices are better. This means that the measured response time is similar to the average of all tested devices (20.9 ms). | ||

| The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 42 % of all devices are better. This means that the measured response time is similar to the average of all tested devices (32.8 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 not detected |  | ||
In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8715 (minimum: 5 - maximum: 343500) Hz was measured. | |||
在只有大约250尼特的情况下，屏幕的亮度不足以在大多数户外环境中使用，而不会出现颜色被洗掉的情况。戴尔Latitude 和惠普EliteBook笔记本电脑的亮度可以达到2倍以上，但它们的零售价也高得多。
业绩
测试条件
在运行以下任何基准测试之前，我们通过Windows将我们的设备设置为性能模式。我们还通过预装的Dynabook设置软件禁用了 "环保模式"。建议用户熟悉Dynabook设置，因为这里可以进行各种设置，包括性能、充电、启动选项、密码等。它甚至包括一个实时功耗读数，这在笔记本电脑上是不常见的功能。下面的屏幕截图显示了一些可用的设置。
处理器
CPU性能非常好，多核结果比平均速度快10%至30%。 酷睿i7-1260P在我们的数据库中。在审查时，该CPU比大多数（如果不是所有的酷睿U系列和Ryzen U系列替代品）都快。
性能的可持续性可能会更好一点。当循环运行CineBench R15 xT时，如我们的下图所示，处理器性能在初始运行后会下降约18%。

压力测试
当在Prime95下受压时，CPU会在前20秒左右提升到3.4GHz，主板功耗为39W，直到核心温度达到最高92C。此后，时钟频率会下降到2.9GHz，最后是2.2GHz，主板功耗为28W，以保持77C的较低核心温度。
运行时的GPU时钟速率和温度 Witcher 3将分别稳定在1397兆赫和75摄氏度，而在联想Yoga 9 14上则是1147兆赫和65摄氏度。 联想Yoga 9 14配备相同的Core i7-1260P CPU。
如果用电池供电，性能会稍微慢一些。在电池上进行3DMark 11测试，物理和图形分数分别为12266和6029分，而在主电源上则为13963和6136分。

消耗功率
桌面上的空转消耗5瓦至9瓦，取决于亮度水平和电源配置文件设置。游戏需要40瓦至52瓦，而大多数其他超极本在运行旧的第11代酷睿U系列CPU时的功耗为30瓦。Dynabook的功耗较高，是由于其更强大，因此对Core-P CPU的要求更高。
我们能够从小型（约6.2 x 6.2 x 2.7厘米）的65瓦交流适配器中记录到68.7瓦的临时最大功耗。

判决--名义上是高级的，但执行起来就不那么容易了
用Dynabook自己的话说，Portege X40-K是一个 "高端商务计算的新时代"。作为一款高端商务笔记本电脑，将其与其他旗舰产品进行比较是公平的，包括 联想ThinkPad T或 X1系列, 惠普EliteBook或 蜻蜓系列，或 戴尔Latitude 7000或 9000系列.从这个指标来看，Dynabook系统在几个关键领域都有缺陷，因为它的显示屏更暗，颜色明显更差，它的重量几乎没有那么轻，它的720p网络摄像头质量很差，而且它仍然使用桶状AC适配器端口和触摸板指纹识别器，而其他高级商务笔记本电脑已经完全过渡到USB-C充电和支持指纹的电源按钮。后面两个特点尤其让Portege X40-K感到老旧，尽管它搭载了最新一代的英特尔CPU。
Dynabook Portege x40-K将高端CPU包裹在一个中端机箱中，并配有一个过时的显示屏。尽管Dynabook与经济型产品有更多共同之处，但它被作为高端商务笔记本电脑进行销售。
上述许多属性使Portege X40-K完全属于经济型商务笔记本电脑类别，特别是在涉及到显示屏时。对于1400多美元，用户可能要考虑运行旧的第11代英特尔CPU的旗舰ThinkPad、EliteBook或Latitude 。处理器性能可能会慢一些，但与Dynabook相比，在几乎所有其他方面的收益都会很显著。不过，如果你真的看重第12代CPU和基本的3年保修，那么Portege X40-K在这方面可以被看作是一笔好交易。
价格和可用性
Dynabook Portege X40-K还没有在网上广泛销售。官方Dynabook网站在发布时只提供配备第11代CPU的SKU。
