Thin and light notebooks have developed to this day, and it is indeed a market with a lot of flowers. The industry does not have a strict definition of thin and light notebooks, so there are all types and models of weight. However, from the products currently on sale, most of their weights are between 1-2kg, and although products under 1kg are available, they are rare. Today, the author specially searched for it. Currently, there are roughly the following thin and light notebooks with weight less than 1kg. Users who have high requirements for body weight, prefer ultra-light bodies and have no gaming needs, can pay attention to this type of model.
01 12-inch: VAIO SX12
Body weight: 899g
VAIO SX12 is an 899g notebook, and it also has Intel's tenth-generation Core i7-10710U, which is a six-core twelve-thread processor . The ultra-light weight, small body, and the one on my hand is cherry blossom pink, which is especially suitable for female users. In addition to the cherry blossom pink color scheme, VAIO SX12 also has Yaoshi Red, Zunyao Black, Golden Palme d'Or, Late Night Black and Moonlight Silver color schemes. Friends who often travel on business or are used to carrying laptops to and from get off work can always find a color scheme that suits them.
02 13 inches: Dell Lingyue 7391
Body weight: 0.955kg
Dell Lingyue 7391 is a mainstream priced nuclear display ultra-light notebook. The machine is 13.3 inches and weighs only 0.955kg. The reference price of its i5 10210U processor, 8GB memory, 512GB SSD, and 72%NTSC FHD IPS screen is 5,999 yuan.
Dell Lingyue 7391 uses an magnesium alloy body, including ACD surface and skeleton and other metal areas. The configuration of this phone is a regular configuration. The screen is a 300 nit high color gamut screen. The camera is at the top of the screen. There are no flaws in the configuration and no big highlights. The main advantage of this phone lies in the after-sales service. Lingyue 7391 supports two-year full-smart service, including hardware door-to-door machine warranty, telephone support, overseas after-sales service and other services. After-sales guarantee is relatively comprehensive and worry-free. The number of interfaces is a bit cramped, and there is only one USB port, but fortunately there is a full-featured Type-C port, which has a certain scalability. The battery capacity is 45Wh, not large. The biggest feature of Lingyue 7391 is its ultra-light body + complete after-sales guarantee, which is suitable for users with high requirements for these two aspects. Also a reminder: The phone also has an MX250 independent graphics version, but the purchase value is not great. It is recommended that you consider the i5 core graphics model.
0314 inches: LG gram 14
Body weight: 999g
LG gram 14 uses a 16:9 1080P IPS screen, with a size of 14 inches, a color gamut covering 96% sRGB, and a maximum brightness of 300nits; due to its smaller size, the weight of the whole machine is only 999g, less than 1kg. Due to its smaller body size and a battery capacity of 72Wh, it is still very large in 14-inch products. In addition, the other parts are basically the same as LG gram 15.
04 14-inch: Thor MixBook Air
Body weight: 1.065kg
Thor MixBook Air is a 14-inch ultra-light notebook with a weight of about 1kg. This model is focused on the i7 processor model, because the battery capacity of different processor versions is different: the battery capacity of the i5 processor version is only 36Wh, while the i7 processor version is 72Wh, and the battery life difference is obvious. The reference price of its i7 10510U, 16GB memory, and 1TB SSD version is 7,499 yuan.
So how do these thin and light notebooks reach less than 1kg?
Let’s talk about the conclusion first. The weight of thin and light notebooks is controlled within 1kg, with two points: one is to use lightweight body materials, and the other is to "leave blank" inside. Let’s talk about it one by one below.
• Use lightweight body material
Currently, many notebooks use aluminum alloys on body materials. Aluminum alloys can not only increase the metal texture of the notebook, but also play a certain role in heat dissipation. It is a material with the best of both worlds. However, its disadvantage is also obvious, that is, it is heavy.

In order to reduce the weight of the whole machine, notebook manufacturers have begun to explore new body materials. For example, the notebooks listed above with weights of less than 1kg use some different materials:
LG gram uses nano-carbon-magnesium alloy, and VAIO S12 uses unidirectional multi-layer composite carbon fiber material.The most common words "magnesium", "magnesium alloy", " magnesium lithium alloy ", etc. So what kind of metal material is "magnesium" and "magnesium lithium alloy"?
Mg (Picture from Wikipedia)
Simplely put, magnesium is a lightweight metal with a density of 1.74g/ cubic centimeters , while lithium is the lightest metal on the earth, with a density of only 0.53g/cc, which is lighter than water (1 g/cc). Magnesium lithium alloy is the lightest commercial alloy, and its density is only 1.48 grams per cubic centimeter, while aluminum alloy has a density of 2.72 grams per cubic centimeter, so under the same volume, the weight of magnesium lithium alloy is almost half that of aluminum alloy.
That is to say, the reason why those thin and light notebooks can control the weight within 1 kg depends largely on the use of lightweight body materials.
• Optimize internal space
Optimize internal space, to put it bluntly, it is weight loss.
In general, thin and light notebooks within 1 kg mostly use the following two methods to reduce weight for notebooks:
First, use lightweight body materials, such as magnesium alloy, magnesium lithium alloy, etc.; second, "leave blank" inside to achieve the purpose of reducing weight.
Finally, let’s talk about whether these thin and light notebooks within 1kg are worth buying. If you need to travel frequently or go out, are very sensitive to weight and can accept prices from around 7,000 yuan to 12,000 yuan, then I suggest you choose a thin and light notebook with a weight of less than 1kg.
