Maibook S431: Lightweight Laptop with AMD ZEN2 CPU

Published by MaiBenBen on September 29, 2020

Introduction

AMD has attracted much attention in performance of the market and desktop processors. The success of ZEN2 architecture is linked with disadvantages of Intel year by year. After all, no one can reject a product with both excellent performance and high cost performance, right?

As some users have higher requirements for lightness and duration of laptops than for performance, AMD explores this market. This year, AMD launched Athlon series processors based on ZEN+ architecture “suddenly”. Name of Athlon occurs again in the list of low power consumption processors after having been silent for many years. It naturally make people feel curious.

As the name implies, lightweight laptops are a series of laptops featured by light hand feeling. These laptops are more attractive than the heavy gaming laptops for ordinary users. With acceptable hand feeling and long duration, these laptops often meet user demands in office applications and daily entertainment.

I got Maibook S431 laptop this time. It is a lightweight laptop using AMD Athlon Gold 3150U processor. The point is it has a very low price. Then how about the craftsmanship and user experience of the laptop? Is it worthy of buying? I’ll explain in this article.

The article will include the following contents:

Summary

Unpacking and Use
I received a huge parcel in the afternoon of one day, and it was outer packing box of S431. Generally there is no problem with transportation with a kraft-paper box.

After unpacking, open another layer to see the main body wrapped by flocked cloth. It is mainly silver with sides A, B and C of aluminium alloy material. The touchpad in the middle occupies a very large area.

The power adapter attached to the laptop has an output of 19V and a power of 39.9W. There is also quick guide and warranty card in the package.

I feel the bezel is really thin at first sight. I can see it slim with naked eyes, and the actual width of the left and right bezels is about 3.1mm.

The weight of the laptop is 1.3kg and the screen is 14 inches. The laptop in my hand is 8GB+256GB.

The metal material offers strong promotion of hand feeling. Compared with laptops using plastic as surface material, it will not have a sense of low price in delicate hand feeling.

Apart from the foot pad, the middle thickness of the laptop is 18mm, in line with the positioning of lightweight laptops. The mold technology is good. I didn’t encounter misalignment or big gaps in the interface.

The maximum opening angle of the screen rotating shaft is 135°. The selling price is not high, but it is well equipped. Even kensington lock holes are provided.

Lock holes, USD interface, 3.5mm headphone jack and MicroSD card reader are arranged on the left of the laptop.

There is HDMI interface, Type-C interface and USB interface, power jack and charging indicator light on the right of the laptop.

Side D adopts plastic casing for skid resistance and insulation on the one hand, and for the design demand of Bluetooth and Wifi antenna on the other hand. As we may only touch this side when we carry it, I don’t think it has much to do with the performance of hand feeling and texture.

Luckily, the MicroSD card slot is self-push type, while many existing laptops are designed as direct-insert type.

At first I think the top is designed terribly, wondering why there is a bulge for the camera.

Then when I used it, I found that the blind opening design is very convenient for people who is used to opening and closing the laptop with one hand. It is a design returning to the original meaning. After all, practicability is more important than beauty of the laptop.

A self-contained fingerprint identifier is same with that of numerous mobile phone manufacturers, which is based on contact capacitance technology. Therefore, its unlocking is same as fingerprint unlocking effect with mobile phone, which has advantages in speed and safety over password.

The keyboard looks like Apple. The actual experience is similar to MBP with a non-butterfly type keyboard, with long key travel. Therefore, there is a sense of rhythm when beating, and character input is satisfactory.

It’s good that the touchpad is large. We can use various touch control methods offered by Win10 conveniently, but I wonder whether typing will touch mistakenly sometimes. I tried and didn’t encounter the problem. If you are really worried about that, the official organization also offers [Fn]+[Esc] to directly disable the touchpad.

The screen of Maibook S431 is IPS screen of 1080P 60Hz, with not bad impressions. Among the equivalent IPS products, its color is not poor, and it can meet most of the usage scenarios. I feel satisfactory when watching movies.

A minor obstacle in design is the arrangement of the power line and Type-C on the right. If you use mouse with right hand, there is a bigger distance between the hand and the computer. The effect will be better if the left and right interfaces are exchanged.

Disassembly
To disassemble the laptop, you need to remove all screws at the bottom, and then overcome the force of friction of clips.

I can see the inside of the laptop after disassembly. The battery occupies about 2/5 of the bottom. As the circuit is covered by PVC sheet, it is not disordered at a glance.

The battery is 8.7V lithium battery from LeCroy, with a capacity of 4830mAh. The capacity can theoretically offer satisfactory duration. I will test it later.
