2.How to measure laptop size？
what size is your laptop?how to know screen size of laptop?How do you measure laptop size?This is a problem that many computer users will mention.To better understand how these dimensions are calculated, look at the following:Height: This is the dimension of the laptop from the bottom to the back of the monitor when the laptop is closed.
Width: The width is measured from the left side of the keyboard to the right side.
Depth: Depth is measured from the front of the laptop to the back.
- Find the specific brand and model of the laptop computer, directly search the laptop name in the search engine, and see the specific parameters.
- You can directly measure the size of the screen, measure the diagonal of the screen, excluding the frame, the measured value is in centimeters, and then converted into inches, 1 inch = 2.54 cm cm, and the final data can be rounded up,then you can get its inches measurements and determine its size.
- If the laptop has a laptop housekeeper, you can use the hardware detection function of the laptop housekeeper, where you can see detailed laptop configuration information, including laptop screen size, model, etc.
- 13.3inch 11.1inch(282mm) 7.1inch(180mm);
- 14.1inch 11.3inch(338mm) 8.4inch(213mm);

3.How much storage do i need on my laptop？
When we want to buy a new laptop, what many people think about the most is how much storage do I need on my laptop? We need to combine the use of the laptop, whether it is playing games, office work, drawing, etc., the memory requirements for different people are also different. First of all, let's talk about the factors that affect the size of the hard disk:
- For office workers:
Office workers generally only use basic office software such as Word and Excel, especially when encountering some large Word documents with a lot of text and pictures, it is often difficult to edit them. In addition, it is often necessary to use image processing software such as Photoshop, which takes up a lot of memory, and opens a few more pictures on various cards. Therefore, it is best for office workers to have 4G or more memory, and 8G is standard. The hard disk does not need to be very large, because it does not need to store a lot of things, and 500G of space is basically enough. - For Gamer:
Like gamers, the current mainstream large-scale 3D games will clearly indicate the minimum configuration, recommended configuration and maximum configuration on the system configuration. And now more and more games indicate that the minimum configuration requires 4G of memory, and even more, such as Call of Duty 10, requires 6G of memory, so you can choose 4G/6G RAM and 256GB or 512GB SSD. Therefore, the memory of gamers is best to be 8G or more. If you play games, you should not only play one or two games, but also play other games occasionally.when your drive is about 80% full, this drive size fills up quickly and performance starts to suffer. Therefore, a mechanical hard disk with a capacity of about 1T is basically enough, the laptop you can choose 8G RAM and 1T SSD. If your budget is enough, gamer can choose 512G SSD + 1T HDD. - For professional users:
For advertising production design, it can handle large-format pictures such as high-precision posters such as 1x2m 300dpi. 4G memory will explode immediately, and the standard 16G will be the best to start. In addition, professional software like 3DMAX depends on the complexity of the model, and generally requires at least 16G memory. There are also some users with virtual machine needs, who also start at 16G and increase the memory as needed. Therefore, professional design users must have sufficient budget. It is best to have 8G of memory. Considering the need to store a lot of design files, 500G to 1TB of memory can be used, depending on personal needs. So the professional user can choose 8G/12G/16G RAM, 500GHDD+ 1TB SSD.
- For ordinary users:
Compared to the previous laptops, the requirements for ordinary users are slightly lower. For general use, you just need to studies, watch movies, listen to songs and other entertainment. 6G is enough, and 8G of standard memory is standard. If you need to store some movies or something on the hard disk, about 512G is good. If your budget is enough, you can mainly study use , for reading documents, study and watch dramas, then you can choose 256G SSD or 512G SSD.
The above are all matched according to the needs of different people. According to the current market, the starting capacity of mechanical hard disk is the best IT capacity, while the starting capacity of memory is 8G. For newly installed or upgraded users, it is recommended to add a solid state drive to improve the speed of the laptops, and the effect is obvious.
4.How many watts does a laptop use？
- How many watts does a laptop use, and what is the actual power? How much is it generally?
The power of each laptop is different, generally around 60W-80W, but it is not actually used. The accessories of laptop are generally designed for low energy consumption, and the power is generally between 1/2 to 1/3 of desktop computers, or even lower.
The power of laptop is generally about 20W, which is highly related to the size of the screen, and also related to the CPU,higher performance CPU require higher wattage draw. For example, the second generation of Centrino saves power compared with the first generation.
The power of the laptop varies depending on the operation you do on the laptop: whether you are surfing the Internet, using an optical drive to watch movies, or using a mobile hard disk, and the brightness of the display screen. The automatic power management system adjusts your power at any time.
The algorithm of laptop power: if the output voltage is 16 volts and the output current is 3.75 amps, then the power of the laptop is 16X3.75=60 watts.The power of the independent graphics laptop is mostly about 90w.
- How much electricity can a laptop use in a day The power consumption of laptop computer is generally about 60W to 80W. If it is a laptop with a general configuration, the power consumption is about 65W. Ultra laptops are more power-efficient, 20 to 40 watts. If it is used 24 hours a day, it will not exceed 2 kWh.
- How much electricity does a laptop consume in a day when it is on 24 hours a day? Usually run a laptop power is about 65W, (AIWO laptop, the rated output voltage of the power adapter (that is, the charger) is 19V, the rated output current is 3.42A, so the rated power is 64.98W,)
Calculation method of electric power consumption:
The power (watts, represented by the letter W) will be marked on the manual or nameplate of the electrical appliance. Usually, the electricity consumption is how many kilowatt-hours of electricity. The amount of electricity consumed by an appliance in one hour.
The calculation method of electricity consumption is as follows:
Electricity consumption (kWh) = power (W) / 1000X time (hours)
Now calculated according to the rated power of 65W, 1000W.hour/65W=about 15 hours, that is, about 15 hours with one kilowatt of electricity.
One hour of electricity consumption is about 0.07 degrees, In other words, a day is 1.68 degrees,Of course this is a theoretical value. It depends on the actual power of your power supply. For example, if you play games, listen to songs, watch movies on the Internet, chat with QQ, and adjust the brightness of the notebook to the brightest, your actual power is definitely not only 65W.
