The memory and hard disk are both storage devices in the computer and assist the operation of the CPU. The performance of the memory and hard disk determines whether the performance of the CPU is fully utilized.
Software and documents are generally stored on the hard disk. When the user runs the software and processes the document, the memory will fetch the corresponding data from the hard disk, and then transfer it to the CPU to run in the CPU. The results of software operation and document processing are generally temporarily stored in memory, and then stored in the hard disk when long-term storage is required.
The speed of accessing data from memory and hard disk cannot keep up with the speed of CPU. Therefore, when purchasing a notebook computer, the stronger the memory and hard disk performance, the more fully the performance of the CPU will be exerted.
There are two main types of hard drives, SSD and HDD.
The mainstream 256GB SSD is more expensive than the mainstream 1TB HDD; there are some SSDs with relatively strong performance, and the price of 256GB is similar to the price of 128GB SSD + 1TB HDD.Therefore, you can see that most models are equipped with 256GB SSD, or 128GB SSD + 1TB HDD.
The equivalent of a desktop desktop computer, a laptop is more difficult to replace or upgrade the internal hardware. In everyday life, laptop keys wear out and accumulate debris or dirt from heavy use. If you need to clean dirty or worn keys, this guide will show you how to do.
If you're looking to expand your laptop monitor to your primary desktop PC and use your laptop as a second monitor, in this article we'll show you how to do that.
Notebooks need to support two-way video transmission when the monitor is used. At present, the HDMI interface of most notebooks only supports output and does not support video input; only a small number of notebooks support bidirectional transmission, such as Alienware. If the notebook itself does not support video input, it can be achieved with the help of a USB capture card. The following is a detailed introduction:1.First connect the display and the notebook through a VGA or HDMI cable, the goal is to display the main screen, and the notebook display is used as a sub display.
The above is the method of using a laptop as a monitor. Generally speaking, as long as the laptop needs to support two-way video transmission, you can turn laptop into monitor.A friend in need can operate through the above steps and hope to help you.
The combination of notebook computer and LCD TV is a computer. In this combination, the TV is equivalent to the original monitor or the 2nd monitor of the computer. As long as the computer host and the TV have matching signal input and output interfaces.The solutions are as follows:
There are two sources of power for notebook computers, one is the power adapter (external power supply), and the other is the rechargeable battery. The service life of a rechargeable battery is determined by the number of charges. Lithium-ion batteries used in laptops can be recharged about 400 times, so be sure to develop good habits: When there is an AC power source available, don't be afraid to plug it in instead of the battery. This ensures that the battery is fully charged when the battery is really needed. If a battery is used, it is best to use it up and then recharge it in one go. 2-3 months for a complete charge and discharge of the battery, so as to maintain the activity of the battery.If your charger is lost or broken, there is 2 ways to charge your laptop without a charger.
Since the car's 12V power supply is not stable enough, it is best not to charge the computer or mobile phone directly from the car charger. After the inverter is converted to 220V AC, and then use the special power adapter for the device to charge, the voltage will be relatively stable and there is no damage to the device.
Since the power supply in the home is generally about 100V-240V (alternating current, AC for short), the power supply on the car and the plane is generally about 12V (direct current, DC for short), but these three commonly used power supplies are unstable. Do not charge the laptop directly, otherwise you will probably end up with a dead or failed battery. The power supply required by the notebook computer is a stable constant voltage direct current.
It is worth noting that this conversion circuit must have a protection circuit (overcurrent protection circuit, overvoltage protection circuit,Short circuit protection circuit, etc.) to prevent accidents and protect the notebook computer from burning. When choosing a charging device for a notebook, you can't choose it casually. You must choose it according to the parameters of the notebook's original adapter.
Just like charging a mobile phone, even if there is no plug, as long as there is a power cord and a power bank, you can charge your laptop through the USB Type C interface. But it is worth noting that usually charging a laptop requires a voltage of 8V to 12V, so the required power bank output voltage needs to be 12V and above.
