When it comes to “unusual” PC brands, the One Notebook definitely ranks high. Previously, they launched an “Alien Handheld”, and this time we got our hands on a super small notebook.
It not only supports stylus, flip screen, but there’s even a serial port on the body!
What is the purpose of a notebook computer equipped with such a “niche interface”?
Today, let’s analyze it briefly:
One Notebook One Engineer PCA1

Its configuration is as follows:
M3-8100Y processor
8G RAM
256G SSD
7-inch 1920×1200 resolution 72% NTSC color gamut 16:10 aspect ratio IPS touchscreen
Battery capacity 31Wh
Thickness 18.4mm
Weight 544g
Adapter weight 140g
Current price 3999 yuan
Its pros and cons are as follows:
Pros!
1. Supports rotating touchscreen and comes with a stylus
2. Compact and lightweight, highly portable
3. Rich interfaces, supports RJ45 network port + RS-232 serial port
Cons!
1. Weak CPU performance, difficult to serve as a main machine
2. Extremely compact keyboard layout, requires familiarization
3. The original charging cable is relatively short, only 1m long

[Upgrade Suggestions]
This notebook is not difficult to disassemble; simply remove the screws of the D-shell to easily take off the back cover.
The machine comes with 8GB of single-channel onboard memory, which is not upgradeable.
The 256GB SSD is a Phison PS5013, M.2 2242 specification, supports PCIe 3.0×4, but the M.2 interface speed of this machine is PCIe 3.0×2, limiting the hard drive performance.
[Purchase Suggestions]
1. Requires nearly ultimate portability experience
2. Needs for serial port and RJ45 network port
3. Not considering it for main machine usage
The biggest feature of the One Engineer PCA1 is its small size + serial port + network port, with a total weight of only 544g, and this variety of interfaces is indeed rare.
Regarding the screen, it supports rotation and comes with a 2048-level stylus, making it very suitable for field operations, such as debugging devices via serial port, surveying blueprints on construction sites, and so on.
This 7-inch screen has a color gamut volume of 85.4% sRGB, color gamut coverage of 79.9% sRGB, with an average ΔE of 3.07 and a maximum ΔE of 7.91. Additionally, the screen color temperature reaches 7900K, which gives it a cool appearance.
In terms of battery life, its PCMark 10 battery life test score is 5 hours and 2 minutes, which is consistent with the performance of a 31Wh battery.
Regarding noise, its full-load human position decibel value is 41.2dB, with a sharp tone.
This computer is clearly targeted at maintenance personnel who need to use serial and network ports in their daily work, and whose work conditions are relatively complex, with no space to operate larger computers.
If you happen to meet this need, I suggest you forward this article to the colleague responsible for procurement, since this type of computer generally does not require you to pay for it yourself
However, if you just want a laptop for daily web browsing and office work, it’s recommended to choose a traditional laptop with a screen size of over ten inches.
[The Pig King’s Conscience Conclusion]
The above image shows the disassembly of the One Engineer PC, featuring a single fan and a single heat pipe combination.
Room temperature: 25.5℃
Reflectivity: 1.0
BIOS version: 5.12
For lightweight laptops without dedicated graphics, we use a low-load Stress CPU for stress testing.
Under full load, the CPU temperature peaked at 75℃, maintained at 72℃, with a power consumption of about 7W, and the frequency was maintained at 2.6GHz.

The surface temperature is as shown in the above image, with the highest temperature occurring near the power button, WASD keys at 40.1℃, directional keys at 34.6℃, and the center point on the back at 40.3℃.
Overall, One Engineer PCA1‘s heat dissipation performance is average; the M3 was originally designed for fanless laptops, so with a fan, you don’t have to worry too much.
You might not believe it, but currently, the colleague responsible for business liaison in the Pen Bar testing room once worked in railway maintenance in Ethiopia for two years. According to his account, this job is nicely termed as a field engineer, but to put it bluntly, it’s just after-sales service.
At that time, the maintenance laptop he used was an ancient HP workstation, mainly because it supported serial ports.
During work, the serial port connection was located in the equipment cabinet below the cockpit, requiring him to lie on the ground to connect properly, making it very torturous while holding a thick brick machine.
One Engineer PCA1 is a product designed to meet the needs of this type of crowd. Their performance requirements may be very low, but their requirements for the size and interfaces of the computer are very specific. Just think about it, who would want to lie on the ground to use a computer? Maintenance personnel need this.
In my opinion, this type of product is destined not to become mainstream; it doesn’t even want to be mainstream. As long as it can solve specific application scenarios well, its historical mission will be accomplished~
