Inspiron 15-5547 uses a mirror touch screen, which provides a smooth experience with no feeling of delay at all; it is also pre-installed with the latest Win8.1 system. Equipped with i7-4510U processor, R7 M265 2G independent display HD4400 core display dual graphics card; using 8G memory, 1T mechanical hard drive, the overall configuration is very excellent. Although it is not equipped with a solid-state drive, the actual boot speed and response speed for daily use are very fast. As an ultrabook, the thinnest point reaches 24.24mm, and with the eye-catching brushed metal top cover, it looks very fashionable and stylish. Unfortunately, although the thickness is slim enough, the weight has not been reduced. The travel weight is as high as 2.78KG, which can only be said to be a passing level among 15-inch notebooks.
The appearance has a strong metallic feel and the touch screen experience is smooth and sensitive
▲The top cover is made of metal brushing process
The Dell Inspiron series has always focused on the beautiful appearance of the product. Fashion. This Inspiron 15-5547 is no exception. The pure silver brushed metal top cover is comparable to Dell's high-end series XPS, and it doesn't have the cheap feel of ordinary notebook plastic shells.
▲The upper part of the top cover is rounded
The upper part of the top cover is rounded, which well neutralizes the excessive toughness of the metal casing, making it very harmonious for female users to use. Fashion. The silver casing is full of metallic flavor and also has a sense of future technology. It looks very coordinated whether at home or in the office.
▲The interior adopts a simple all-black color scheme
Lingyue's products are widely applicable and are equally suitable for business and home use. The interior adopts a simple all-black treatment and uses skin-like materials, which feels excellent to use. However, the more painful thing is that it can easily leave fingerprint marks and requires regular care to maintain its beauty. ?
▲Adopts 1080P full HD touch screen
▲The screen supports handwriting input
This Inspiron 15-5547 adopts 1080P full HD touch screen screen, which performs well on the color and brightness of the picture. I chose a mirror screen with better brightness, and there is no obvious color cast when viewed from left and right angles. However, the use of reflection in a well-lit environment is also more obvious. This ultrabook, which uses touch as its selling point, has a very smooth touch operation experience. Whether it is daily software operations, browsing the web, or directly using the screen for handwriting input, it is very sensitive and there is no feeling of delay. However, when using the screen to draw with drawing tools, you will feel a little frictional resistance. After long-term touch screen operation, a lot of fingerprints will be left on the screen, so it is recommended to apply a screen protector.
▲Using an island-style chocolate keyboard
The mainstream island-style chocolate keyboard is not only beautiful, but also easier to clean. Due to the limitation of the thickness of the whole machine, the key travel of the keyboard is short and the feel is slightly hard. However, the key design is very reasonable and the spacing between keys is large, which improves the typing experience. Dell still swaps the F1-F12 traditional function keys with the multimedia function keys, but users can modify this setting in the BIOS settings. The touchpad adopts an integrated design, supports gesture functions, and feels very smooth. The skin-like palm rest is very comfortable, but it leaves marks easily and requires regular care.
▲The surface of the keycaps is frosted
The keycaps of the keyboard are frosted, and the feel is excellent when touched. The relatively closed keycaps and larger key spacing make dust easier to clean. The uppercase and lowercase switching keys also provide switching indicators, which is very considerate.
▲Integrated touch panel
The integrated touch panel feels very smooth, the left and right buttons are relatively sensitive, and it supports gesture functions.
▲The thinnest part of the fuselage is only 24.24mm
The maximum opening and closing angle of the screen is about 130 degrees, and the thinnest part of the fuselage reaches an excellent result of 24.24mm. It looks incredibly slim from the side.
▲The back of the fuselage adopts a quick-release plate design
▲Internal structure
The back of the fuselage adopts a quick-release plate design. Tighten the two fixed screws. After downloading, it can be opened very easily. It is more convenient for daily dust cleaning or later upgrade.
▲Interface configuration
Inspiron 15-5547 provides 2 USB3.0 interfaces, 1 USB2.0 interface, HDMI interface, RJ45 network interface, card reader and headphones The two-in-one microphone interface has rich configurations and can basically meet daily needs. The built-in optical drive has been removed due to size reasons, which is also the current mainstream approach for ultrabooks.
▲Weight: 2.4kg
As a 15.6-inch ultrabook, the thickness is controlled within the range of 24.24mm~24.41mm, which is relatively slim. The bare machine weight is 2.422kg, and the travel weight with the power supply is 2.78kg. It is still a bit heavy and suitable for carrying in a backpack.
Provides 1TB large-capacity hard disk graphics card to support low-demand games
In terms of hardware configuration, the Dell Inspiron 15-5547 tested this time is equipped with the fourth-generation Intel Core i7-4510U processing The machine provides 8G memory and 1T mechanical hard drive, and uses AMD's new generation independent graphics card Radeon HD R7 M265 2G independent display. The whole machine has excellent battery life and a very excellent touch experience. It is mainly suitable for audio-visual entertainment or daily office work, and its gaming performance is weak.

The fourth generation Intel Core i7-4510U processor, main frequency 2.0GHz, maximum frequency 3.1GHz, It has two physical cores, supports Intel Hyper-Threading Technology, has a TDP of 15W, and is an upgraded version of the i7-4500U. It has a wide range of applications and mainstream performance, and is basically sufficient for daily web browsing and audio and video games. At the same time, lower power consumption brings lower heat generation and longer battery life.

It has 384 stream processors, a main frequency of 980MHz, a bit width of 64Bit, and a capacity of 2GB DDR3. Judging from the 3DMARK 11 running score, it surpasses the previous generation HD8750M graphics card with the same positioning. It is more suitable for ultrabooks with limited size and space. It can run "Devil May Cry 5" and "Metal Gear Rising: Revengeance" smoothly at 1366*768 resolution and low image quality, which require higher graphics card performance. Low game.
Game actual measurement
▲"Devil May Cry 5" low-definition actual measured frame number
"Devil May Cry 5" is another game after "Devil May Cry 4" The biggest difference between this new game and its predecessor is that CAPCOM did not participate in the direct production of this game. Instead, it was developed by Ninja Theory, a studio that had produced "Skyward Sword". This game does not have very high requirements on the graphics card and can run smoothly at 1366*768 resolution and the lowest image quality.

▲Game test screen
The R7 M265 is only suitable for occasional light gaming needs, or for running low-demand online games such as "League of Legends" at low image quality. For an ultrabook that focuses on audio-visual entertainment and touch experience, we don’t need to be too demanding on the performance of the graphics card. Such results are already qualified.
The temperature of the 30-minute copy test is within the acceptable range
▲The temperature is mainly concentrated on the right side of the keyboard
After the 30-minute copy test, the surface of the keyboard The highest temperature was 44.8 degrees, mainly concentrated at the air outlet on the right side of the keyboard and the palm rest. You will feel a little discomfort in the palm rest, and it is recommended to equip a notebook cooling pad with long-term use. Considering that the thinnest part of this ultrabook is only 24.24mm in size, this result is within an acceptable range. After all, you can’t have your cake and eat it too.
▲The highest temperature on the back is 45.6 degrees
After copying the machine for 30 minutes, it can be found that the temperature on the back of the fuselage is mainly concentrated at the air outlet, with the highest temperature being 45.6 degrees, and the average temperature remaining at 30 It can basically guarantee the stability of daily use.

The minimum thickness is controlled to 24.24mm, and the brushed metal top cover makes it look very stylish, but the 2.4kg body weight needs to be strengthened.
