How to choose a graphics card for a laptop? How to check if a laptop is new?

Recently, I found that many friends have not noticed this problem. Not removing the battery when using an external power supply not only affects the battery life, but also makes the heat dissipation burden of the laptop heavier, shortening the life of the laptop. Have you learned it? In addition, today we are learning how to choose a graphics card for a laptop, hoping to have a good computer that satisfies your needs, so that you can work and study more efficiently.

How to choose a graphics card for a laptop

1. First, let’s talk about core graphics cards. What is a core graphics card? It is a graphics card integrated in the CPU, which we call a core graphics card.

2. The performance of the core graphics card can meet the needs of playing 1080p high-definition movies and running general 3D games. People who do not have high requirements for display performance do not need to purchase a graphics card separately.

3. Next, let’s talk about integrated graphics cards. Many laptops have integrated graphics cards on their motherboards. The performance of this type of graphics card is very low or average.

4. Therefore, for buyers who only want to watch some non-HD movies, do some documents or browse some web pages, this integrated graphics card is sufficient.

5. Finally, let’s talk about discrete graphics cards. Some users may not be satisfied with the functions of core graphics cards and integrated graphics cards, so many laptops now use discrete graphics cards. Discrete graphics cards are equipped with independent video memory and have high performance, but they generate a lot of heat and consume a lot of power.

6. For users who often do 3D rendering work or play large 3D games, the laptop must be equipped with a powerful independent graphics card.

7. However, not all independent graphics cards have very powerful performance. Some independent graphics cards are also very ordinary. Don’t think that the performance of this laptop is good when you see the independent graphics card. You also need to judge the pros and cons based on the specific model and parameters.

How to check if the laptop is new?

1. First, right-click this computer on the desktop and select Properties to enter the computer properties interface and click Control Panel Home.

2. Select System and Security in the Control Panel, enter the System and Security interface, click Administrative Tools, enter Administrative Tools, and then double-click Computer Management.

3. Enter the system tool, event viewer, windows log system in sequence. In the log list, click Filter Current Log on the right. In the ID box of the filter interface, enter 6005 and 6006 as separations. 6005 is the startup time and 6006 is the shutdown time.

4. Then click the OK button to see the relevant information of the notebook. For new hardware, its manufacturing date must be close to the current date. Hard disks generally do not display the manufacturing date, but the usage time. New hardware hard disks must not be used, or the merchant has turned on the machine for debugging and installing the system after receiving the goods, resulting in a short number of times of use. In short, new hardware will not have too long usage time and boot times.

How to maintain laptop battery

1. When charging for the first time, you should charge the battery continuously for 12 hours and cycle it fully charged and discharged 3 times to fully wake up the new battery.

2. If you use an external power supply for a long time, it is best to remove the battery. Many friends have not noticed this problem. Not removing the battery when using an external power supply not only affects the battery life, but also makes the heat dissipation burden of the laptop heavier, shortening the life of the laptop.

3. Charge and discharge regularly. Even lithium-ion batteries without memory effect have a certain inert effect. If not used for a long time, the lithium ions will lose their activity and need to be reactivated. Therefore, if you do not use the computer for a long time (3 weeks or longer) or find that the battery charge and discharge time is shortened, you should fully discharge the battery before charging it. Generally, you should fully charge and discharge it at least once a month.

4. It is best to turn off the laptop when charging so that the battery can be fully charged. Do not unplug the power supply during charging. Charging with the laptop turned off will shorten the charging time by more than 30% compared to charging with the laptop turned on, and it can also extend the battery life. It is best to use the laptop 30 minutes after charging is completed.

5. Avoid exposure to sunlight, moisture, chemical liquid corrosion, and avoid short circuits caused by contact between battery contacts and metal objects. The number of charge and discharge times of lithium batteries generally does not exceed 800 times. Each charge shortens its life.
