preface:

With the release of Xiaomi Notebook on July 27th this year, products like "Ultrabook" have been pushed up again. According to the Baidu index query of the word "Ultrabook", we can see that the word has an obvious upward trend in search, and we can also see that the market demand for "Ultrabook" is also very large! In addition to Xiaomi notebooks, do we have more "super extreme" choices with high appearance and good price? Today, I would like to tell you about this super book "Lefan S1" with a 2K resolution screen design!

I won't tell you more about the packaging and accessories of Lefan S1, because there is only one charger for accessories. In terms of appearance design, there is only one gold color for Lefan S1 to choose from, while the laptop shell is made of all aviation aluminum alloy, and the anodizing process is used on the shell, making the Lefan S1 shell feel very delicate.

Lefan S1 has a high face value. The overall design adopts the diamond cutting process, which makes people feel very elegant and thin. Maybe not many people know about the Lefan brand, but from the various design details of Lefan S1 notebook, Lefan is also very quality oriented, so I think it is not necessary for big brands to have good workmanship and quality. Other domestic "small brands" also have excellent products.

The thinnest Lefan S1 Ultrabook is 5.8mm. Compared with my iPhone, you can see how thin Lefan S1 is!

In addition, when it comes to thinness, it reminds me of one thing on the release of Xiaomi Notebook, that is, "thinner than a dollar coin".

Lefan S1 is mainly divided into 128G SSD, 256G SSD and 512G SSD, The CPU uses the Core M processor, the running memory uses 8G, and the graphics card uses an integrated graphics card. In addition to these, the most distinctive hardware design of Lefan S1 is to use a 13.3-inch IPS colorful screen with a resolution of 2560 * 1440. You can also select a customized version of the built-in 4G flow module, and plug in the SIM to access the Internet.

Lefan S1 adopts the popular tpye - c data interface, and this type - c interface also supports the dual charging function, and can also be used with Apple Macbook accessories! Let you use it more "cool"!

In addition to using the popular type - c interface, Lefan S1 also has USB 3.0, USB 2.0, 3.5mm headphone interfaces, and Micro HDMI interfaces. The rich interface design also makes this Ultrabook more practical.

The first thing I see when I open the Lefan S1 is the full fitting 13.3-inch display screen. Even if I use the Lefan S1 in the high contrast sunlight, I don't have to worry about not seeing the screen clearly. How excellent the display effect of the Lefan S1 screen is, I will make a careful evaluation at the end of the article. In short, the 2K resolution screen display of the Lefan S1 is very exquisite, which is not as "egg sore" as that of ordinary laptops Mosaic.

Let's talk about the keyboard experience of Lefan S1. Lefan S1 uses a full-size keyboard design, with moderate key spacing, good press rebound, comfortable press, and timely response. If you are a typing office party, I believe Lefan S1 will satisfy you.

Lefan S1 also designed some decorations on the axis between the screen and the keyboard, making the whole product more scientific and technological. This may also be the only pattern design of Lefan S1. The rest of the body design can be described as "simple".

The touch pad design of Lefan S1 is a circle larger than that of other notebooks, which increases the range of touch. The left and right key holders of the touch pad are also large, which is very suitable for office workers who type for a long time. The workmanship of the touch control panel, the rotating shaft and the keys is fairly good. There are no gaps due to the workmanship.

The back of the Lefan S1 is the same as the front, which is very simple. In terms of battery life, the Lefan S1 has a built-in battery of 9600 mAh. The battery life is about 5 - 7 hours, which is enough for daily office use.

A total of 4 anti-skid silicone pads are designed on the back of the fuselage, and because of the design of this anti-skid silicone pad, the speakers on the back of the fuselage will not be blocked.

Here I also want to tell you one of the design highlights of Lefan S1, that is, this Ultrabook supports the replacement of your own DIY hard disk, but only the replacement, not the expansion of an additional hard disk.

Lefan S1 also provided a screwdriver and gloves in the package. This detail is worthy of praise.

The way to remove and replace the hard disk is very simple. You can find a child to be competent. In addition, the SSD process uses NGFF specification M.2 interface.

There are few models that use 2K resolution screens on Ultrabooks, and most of them stay at 1080P. I believe that when you are used to the Lefan S1 with 2K resolution screens, you will never want to use laptops with 1080P screens again.

The Lefan S1 Ultrabook weighs only 1.15kg, which is very suitable for mobile office workers, as well as junior and junior college students. Light and thin, metal machine height and appearance, 2K screen, these are the advantages of Lefan S1.

In the week when I invited my sister to experience Lefan S1 Ultrabook, most of her was used to write word documents. I think if the keyboard keys of this home-made Ultrabook are not comfortable, she will not be used to write documents.

Although it is said that Lefan S1 is a super notebook for positioning mobile office, I personally feel that its performance is pretty good. It scored 93 thousand points after being evaluated and experienced by Master Lu in private. Therefore, in addition to some video card games with special requirements, it is also possible to play ordinary casual games with Lefan S1 or online games with low requirements! But please don't compare Lefan S1 with the game book, because Lefan S1 is a super book!

Well, finally, let's talk about the screen display effect of Lefan S1! The contrast with Lefan S1 is a laptop with a resolution of 1920 * 1080. You can see that the screen display effect of Lefan S1 is close to the original picture, and the picture is bright, while the display effect of other laptops is dark, and the brightness is not high, and the details of the black bread below can not be seen clearly. This shows that the Lefan S1 screen is not only as simple as 2K resolution, but also performs well in display brightness.

In this group of photos, Lefan S1 also performed well, while other notebooks were dark and dark.

In the last group of display effect tests, the display effect of Lefan S1 is completely close to the original picture, while the display effect of other notebooks is still the same. Through the comparison of these three groups, it is not difficult to find that the 2K resolution display effect of Lefan S1 is excellent. It has both appearance and excellent display effect. I think there is no reason to refuse this ultrabook, right?

Experience summary:

As a 2K resolution Ultrabook, Lefan S1 also supports DIY hard disk disassembly. I think the price should be reasonable, and the weight of 1.15kg is undoubtedly the favorite of schoolgirls, office white-collar workers, and office users who often travel. Because it is light and thin, it is convenient to take it to the classroom and dormitory! If you are looking for a slim, high appearance Ultrabook recently, then I believe Lefan S1 should be a good choice!
