HP EliteBook 840 Aero G8回顾。可能是我们见过的最安静的英特尔EVO笔记本电脑
EliteBook 800系列由惠普的中高端商务笔记本电脑组成，与低端的ProBook系列或高端的EliteBook 1000系列形成对比。我们今天的型号是14英寸EliteBook 840 G8，以接替去年的EliteBook 840 G7。该系统采用了与G7相同的机箱，同时将内部设备更新为11代英特尔Tiger Lake-U选项。此外，还有一款名为EliteBook 850 G8的15.6英寸版本。
配置广泛而多样，与大多数其他EliteBook机型不同。CPU选项从Core i5-1135G7到i7-1185G7（带vPro），250-nit到1000-nit显示屏，4GB到64GB内存，可选的5G Nano-SIM和eSIM支持，以及128GB到2TB PCIe NVMe SSD。所有SKU都配有集成的Iris Xe图形和1080p面板。
替代品包括其他高端14英寸商务笔记本电脑，如 联想ThinkPad T14s, Vaio Z, 戴尔Latitude 9420, 或 MSI Summit E14.

案例 - 更加清晰和短小
G7的拥有者不会因为跳过G8而错过什么，除了所有的内部性能更新，因为它们都共享相同的底盘。老款EliteBook 800笔记本电脑传统上比价格较高的EliteBook 1000机型更圆、更厚，如 EliteBook 1030或 1040但840 G7/G8的设计使800系列从视觉角度上更接近1000系列。
机箱质量很好，只是在键盘中心或底座或盖子的角落有轻微的弯曲。外盖中心可能是最容易出现弯曲的地方，这在大多数笔记本电脑上是很常见的。这 戴尔Latitude 9420比我们的惠普更坚固，尽管是以额外的重量为代价。
惠普将底部边框缩小了近20毫米，与老款产品相比，外形尺寸更小，重量更轻。EliteBook 840 G5设计。该系统比许多替代机型略厚，如联想 ThinkPad T14s G2Vaio Z，或微星Summit E14，但与更显著的尺寸和重量节省相比，这一缺点是次要的。
连接性 - 现在有了Thunderbolt 4
与老款EliteBook 840 G5相比，端口选项已经发生了变化。不再有RJ-45和专有的对接端口，而是与Thunderbolt 4配件兼容的第二个USB-C端口。桶装充电器端口仍然存在，意味着用户可以选择通过桶装或通用USB-C为系统充电。
如果将USB-C端口沿左右边缘分布，以方便充电，这将是更好的做法。 雷蛇Blade Stealth或Vaio Z。
通信 - 兼容5G
大多数SKU配置了英特尔AX201，用于Wi-Fi 6和蓝牙5.1连接。当与我们的Netgear RAX200测试路由器配对时，传输率很高且稳定。
网络摄像头
安全问题
惠普包括一套Windows内外的安全功能，这是EliteBook系列和Spectre系列的一个关键区别因素。物理网络摄像头快门、DriveLock、安全擦除、TPM 2.0、可选的Scart Card、Sure Click和BIOSphere只是其中几个例子。
维护
底部面板只需要一把飞利浦螺丝刀就可以打开，庆幸的是橡胶脚下没有藏着螺丝。机主可以接触到M.2 2280存储槽、M.2 WLAN模块和两个SODIMM托架。
配件和保修
除了文件和USB-C交流适配器外，零售盒中没有任何额外的东西。然而，有很多惠普品牌的配件，包括USB-C对接站、适配器和套筒可用。
一年有限的制造商保修是标准的，而更昂贵的EliteBook 1000系列则是三年。
输入设备 - 完全没有弹性
键盘
惠普Spectre和EliteBook键盘是我们最喜欢的一些键盘，因为它们比其他商务笔记本更好地平衡了反馈、行程和咔哒声。特别是反馈更加清晰，避免了轻薄型设计中常见的海绵感。
两级单区白色背光灯是标准配置。
触摸板
惠普保留了老款EliteBook 840 G5的点击板面积为11 x 6厘米。这比微星Summit E14上的点击板要小一些。 MSI Summit E14(10.5 x 6.5 cm)，但惠普实际上配备了专用的鼠标按钮，以获得更可靠的多点触摸输入。滑动非常顺畅，即使在慢速时也很少粘连，而鼠标按钮和点击板都很牢固，按下时有响亮的咔哒声。
显示器--16:9正在变得陈旧
HWiNFO只能识别出AU Optronics AUO068B控制器，但不能识别出面板的具体型号。尽管如此，我们的测量结果显示，在大多数方面都有出色的表现，包括高对比度、广泛的色彩覆盖和明亮的400尼特显示，以证实惠普声称的400尼特面板。
该显示器的主要缺点是其黑白和灰度响应时间慢，特别是在运行游戏时有明显的重影。也没有4K或OLED选项，而一些商务笔记本如 ThinkPad X13或戴尔Latitude 9420已经转向更理想的16：10长宽比。

色彩覆盖率为98%的sRGB，比老款EliteBook 840 G5的面板略好。该机型目前没有提供完整的AdobeRGB或P3覆盖选项。
这款显示器开箱即被校准，平均灰度和彩色DeltaE值分别为3.7和2.84。然而，色温却略微偏冷。

在阴凉处，户外能见度还不错，特别是由于哑光面板的眩光非常少。我们建议通过英特尔图形命令中心软件禁用显示节能功能，否则在电池供电运行时，最大亮度会从466尼特自动降至399尼特。
惠普提供了更亮的1000尼特面板选项，比其他大多数商务笔记本电脑有更好的户外可视性。
业绩
所有EliteBook 840 G8 SKU都配备了第11代英特尔Core-U CPU。对于AMD的选择，你必须看看EliteBook 845 G8，它省略了英特尔驱动的EliteBook 840 G8的一些功能，如5G和Thunderbolt支持。
处理器
原始多线程性能比平均水平低约15％。 酷睿i7-1185G7在我们的数据库中的笔记本电脑。与微星Summit E14这样配备完全相同的处理器的产品相比，涡轮增压性能也不像预期的那样可靠。我们怀疑惠普坚持更安静的风扇噪音阻碍了处理器在更高的时钟速率下运行更长时间。
降级到 酷睿i5-1135G7或 1145G7 配置，与我们的酷睿i7-1185G7配置相比，预计会有10%到15%的性能下降。

PCMark的结果比采用相同处理器的大多数其他超极本要慢一点，可能是由于上述较低的CPU性能。这种差异很小，在大多数任务中是无法察觉的。

Emissions
系统噪音 - 最高时为30分贝(A)
惠普将风扇噪音作为重中之重。即使在高性能电源配置文件上运行Prime95等极端负载时，风扇噪音也会在30dB(A)以下，成为我们评测过的最安静的14英寸笔记本电脑之一。运行同样的测试，在 Vaio Z或 ThinkPad T14s G2上进行同样的测试，会导致更响亮的风扇噪音，如下表所示。
尽管噪音很低，但惠普的风扇很少会空转，以获得完全无声的体验。在浏览或网上冲浪时，在24.1 dB(A)的无声背景下，预计会有大约27至28 dB(A)的勉强可见的风扇噪音。
当把耳朵放在键盘按键附近时，我们能够注意到轻微的电子噪音或线圈啸叫。

温度
表面温度最热的地方是热管所在的后部中心。这些热点的温度在键盘上可以达到39℃，在底部可以达到52℃。后一个热点的温度尤其高于预期；例如，在类似条件下，Vaio Z的底部温度只有45摄氏度左右。
(+) The maximum temperature on the upper side is 39.2 °C / 103 F, compared to the average of 34.3 °C / 94 F, ranging from 21.2 to 62.5 °C for the class Office.
(-) The bottom heats up to a maximum of 51.2 °C / 124 F, compared to the average of 36.8 °C / 98 F
(+) In idle usage, the average temperature for the upper side is 29.8 °C / 86 F, compared to the device average of 29.5 °C / 85 F.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 29.2 °C / 84.6 F and are therefore cool to the touch.
(±) The average temperature of the palmrest area of similar devices was 27.6 °C / 81.7 F (-1.6 °C / -2.9 F).
压力测试
当用Prime95测试时，CPU在达到100摄氏度的核心温度之前，会在一两秒钟内提升到4.3GHz。然后，时钟频率会迅速下降到更稳定的2.1GHz范围，以保持约83摄氏度的较低核心温度。 微星Summit E14配备相同的酷睿i7处理器，将导致更快的时钟频率和更热的核心温度，分别为3.0 GHz和91 C。惠普很可能通过提高风扇的噪音上限来提高性能。
用电池供电运行会降低性能。在电池上运行的3DMark 11将返回物理学和图形学分数，分别为7559和5603分，而在主电源上时为8974和6715分。

发言人
对于一台14英寸的商务笔记本电脑来说，音频质量非常好。低频的滚降是平滑的，而不是突然的，因此低音的再现比预期的要好。不过，最大音量还可以再大一点。

Energy Management — High Performance-per-Watt
消耗功率
在我们的设备上，最低和最高亮度之间的差异略低于2.5瓦，而这在配备1000尼特面板的配置上可能会更高。该系统总体上非常省电，这一点不足为奇，因为这已经成为搭载Tiger Lake-U的超极本的一个共同主题。运行需要GPU的负载时，耗电量几乎与EliteBook 840 G5相同，而图形性能却快了300-400%。
在运行Prime95时，我们能够从小型（约8.9 x 5.3 x 2.2厘米）的65瓦交流适配器中测量到66.5瓦的最大消耗。这个速度只是暂时的，如下图所示，与我们在上面的Turbo Boost压力测试中观察到的情况不一样。

电池寿命
用户可以期待大约11.5小时的实际WLAN使用时间，比我们在老款HP EliteBook 840 G5上记录的时间长约4小时。考虑到电池容量几乎保持不变，这已经相当不错了。
从空电到满电大约需要70到80分钟。

评语 - 渴望16:10的升级版
惠普推出的EliteBook 840 G8让人眼前一亮。它的功能包括NFC、5G、Thunderbolt 4、智能卡和可选的1000尼特面板。 戴尔 或 联想 甚至戴尔或联想也无法在其目前的任何商务笔记本电脑上提供。优秀的键盘和点击板，易于升级，电池寿命长，以及令人惊讶的安静的风扇噪音，使其成为你能买到的最好的EliteBooks之一。替代产品如 Vaio Z或 ThinkPad T14s G2在运行更高的负载时，声音明显更大。
如果你正在寻找市场上最安静的Tiger Lake-U EVO笔记本电脑，这是最佳选择。然而，对于最好的Tiger Lake-U的性能，你可能要检查其他地方。
非常安静的风扇上限是以处理器性能为代价的。涡轮增压的可持续性受到影响，因此整体的处理器性能比配备相同的Core i7-1185G7 CPU的普通笔记本电脑要慢15%到20%。如果需要的话，我们更希望有一个软件或BIOS选项来提高风扇上限，以获得更高的性能，但我们怀疑大多数用户会喜欢更安静的风扇。
对于不可避免的G9的发布，我们预测惠普将把该系列转移到一个新的16:10的外形尺寸，这很快成为商务笔记本电脑的最新趋势。除此之外，该系统几乎在所有方面都令人印象深刻。
价格和可用性
惠普EliteBook 840 G8现已通过亚马逊广泛在线销售。,Newegg,Walmart，以及直接从HP.com起价约为1500美元，我们的具体配置为2300美元。直接从惠普订购将提供最多配置选项。
