Choosing a good notebook can be your right-hand assistant in your life and office. Many small white users don't know that there are many skills in choosing notebook, otherwise they will be completely destroyed. So How to choose notebook? The following small edition to bring you notebook purchase strategy, I hope to help you!
2017 notebook purchase tips
I. household notebook
For home notebook, price is the primary consideration. The basic psychological price is between 3000 yuan and 5000 yuan. The performance requirements are relatively not too high. As long as it can meet the needs of online chat, video viewing, word processing and entry-level games, etc., the requirements for mobile portability are relatively low, and the endurance is not too high Such as Lenovo, Dell, HP, etc.
For notebook configuration, it is recommended to choose a 14 inch screen, of course, the 15.6 inch large screen is also the mainstream choice. The processor is recommended to be equipped with I3 or i5 CPU, 4G memory, 500g hard disk or 128G solid-state hard disk, and an entry-level independent graphics card.
II. Commercial notebook
For commercial notebooks, portability and endurance must be considered. The weight of the notebook is no more than 2kg, and the endurance is no less than 4 hours. For brands, it's better to choose ThinkPad or apple macboook. After all, it's a facade.
As for performance, we can only make selective sacrifices, and the price of such business notebook is certainly not cheap. For configuration, it is recommended to choose 12 / 13 inch screen, i5 or i7 CPU, 4G or more memory, 128G or more solid-state drive, and non independent graphics card. In addition, some of them are also good choices.
III. game notebook
As for the choice of the game notebook, the first consideration is naturally that the performance CPU and graphics card of the whole machine should be highly matched, while the brand can consider the merchants who are developing the main game notebook in recent years, such as Raytheon or the mechanical revolution, while the traditional manufacturers have also promoted a series of notebook products which are the main game, but the price advantage is not obvious.
As for endurance and portability, it can be ignored. For notebook configuration, it is recommended to use i5 or above, i7 processor, 8GB or higher DDR4 memory, 128G solid-state hard disk plus 500g mechanical hard disk, and gtx1050 / 1060 or above graphics card.
Using skills of notebook
1. When you are dealing with text content, it is very wise to reduce some brightness and contrast This can save a lot of power resources. You need to know that this screen can account for as much as 30% of the overall power consumption. At the same time, when processing text content, reasonable brightness and contrast will not stimulate the eye too much, but also play a role in protecting vision.
2. The new generation of i5 and i7 processors have the function of riff, which is actually the automatic overclocking within the range allowed by the manufacturer. However, compared with the increased 5-10% performance, it is hard to detect. The price paid is the increase of power consumption and the terrible heat dissipation. Generally, in the CPU performance of power management, the maximum performance is set to 99%, so that the REMAX function will not be automatically enabled.
3. When you do not use this book temporarily, the standby function is very convenient. You can start it by covering the screen, but the power consumption is the same. Instead of using the sleep function, the startup speed is only ten seconds slower than the standby speed, but this function will not consume power, saving a little bit.
4. If you don't use the battery for a long time, you can unplug it and use only the alternating current. However, it's better to charge and discharge the battery once a month. Pay attention to that the battery is fully charged (at least 60%) before unplugging. If you don't use the battery for a long time, you can easily 'starve' the battery, because the battery is slightly discharged even when it is taken down.
5. Heat dissipation. If you feel hot in summer, you'd better use cooling (fan) equipment; [2]
6. Maintenance is to keep the computer clean at ordinary times. Try not to use it in dusty places. If there is no film on the LCD screen, you don't need to wipe it if it is dirty. The more you wipe it, the easier it is to scratch.
Notebook maintenance methods
1. Turn off the computer when you go out
Because the computer is still on, and the hard disk is still working in the background. When you go out, you will encounter some vibration or bump, which will damage the hard disk. Although many computers now use the solid-state hard disk, which is much better than the mechanical hard disk in terms of earthquake resistance, in case of going out, try to shut down the computer as much as possible.
2. Do not force shutdown
Due to the forced power failure, the hard disk is still working. After the power failure, the hard disk head is reset under the rotation of the disc, but the data writing will be terminated, the cache data will be lost, and the system will crash seriously. So don't force the computer to shut down. Shut down the software running in the computer, and then shut down.
3. Use of battery
Nowadays, people usually charge the laptop battery only when it is used up. In addition, the battery should be unplugged when it is plugged in. In fact, there is a misunderstanding. Nowadays, the laptop battery is lithium battery. Recharging when it is used up is useless or even harmful. Unlike nickel battery, lithium battery has no buffer effect. And the battery power will be scrapped soon when it is full for a long time, so it is best to keep the battery power between 20% - 80%.
4. Screen protection
The notebook has been used for a long time, and there is a lot of dust on it. It needs to be wiped with a soft cloth (computer off). To avoid using the computer in the place with strong light, the LCD screen temperature is too high to accelerate aging. When using the computer, the intensity will reduce the brightness and extend the service life. The strength does not need to touch the screen directly, so as not to damage the surface coating of the screen and affect the display effect.
5. Notebook dust removal
Due to its small size and high heat output, the notebook has only one hot air outlet. After a long time of use, some dust will block the air outlet and the cooling fan inside, causing the computer to crash and shut down due to the high temperature. So we need to regularly remove the accumulated dust for the notebook. The general notebook only needs to open the back version to remove the dust for the computer. If you dare not do it yourself, you can also go to a professional maintenance shop to remove the dust.
The development trend of notebook
Today's notebook computers are differentiating into different trends according to their uses. Netbooks tend to be used in daily office and movies, business books tend to be stable and low-power consumption, and get longer endurance. Home books have good entertainment performance and high cost performance. Game books are specially designed to cater to a small number of people who go out to play, with fever level configuration and good entertainment experience effect However, the price is not low and the endurance is not ideal.
With the same configuration, functions, thin body and light weight, this kind of laptop can truly reflect the so-called "notebook" feeling.
According to a foreign media survey, the volume of commercial notebook computers has been developing in the direction of smaller and smaller, and the function and configuration have not 'shrunk'. Compared with sub notebook, this kind of laptop can really be called laptop.
According to the report, with the continuous improvement of the notebook industry technology and the launch of the second generation of sandy bridge processor, the 8-12 inch screen notebook computer has become a simple notebook computer, and is tending to the balance of price, performance and portability. The internal configuration of ultra-thin notebook computers, no matter from processor, memory to hard disk and other major accessories, is never inferior to those large notebook computers in terms of performance. Of course, there is no difference. The most obvious reason is that general ultra-thin notebook computers generally do not use high-end configuration due to volume, heat dissipation and other reasons. In addition, the battery volume also determines the relationship between performance and endurance to a certain extent.
Light and thin netbooks generally do not use the built-in optical drive, wireless local area network (WLAN), Bluetooth and other functions have long been popular, the size is also light. However, high configuration is not without cost. We all know that the price of high configuration ultra-thin laptop is not amiable.
