Lenovo is a company that specializes in producing computers. Its main sales scope is domestic, and there are also a few foreign sales channels, but most of them are Chinese people buying this computer. Lenovo was founded in 1984. It has been more than 30 years now. It is considered a very old computer company. Therefore, the computers it produces are acceptable in terms of quality and technology, and the price is acceptable. It’s not too high. After all, Lenovo is not the only domestic computer manufacturer. Therefore, in order to compete, its computer products have not set very high prices.
Lenovo price of g500
Lenovo g500 is a laptop launched in 2013. The price at that time was 4,000 yuan. Now it should only cost more than 3,000 yuan. arrive. Prices are from the Internet and are for reference only.
g500 Lenovo review
Advantages: The i7 version of the G500AM graphics card is HD8750m DDR3, not HD8570m. The graphics card is okay. The CPU is 3612QM low-voltage quad-core (TDP 35W), and the performance is better than Ordinary i5 is more than 75% higher. The heat dissipation is okay, the maximum temperature is 75 degrees with Turbo frequency on, and the maximum temperature is 65 degrees without Turbo frequency. The C surface is painted metal.
Disadvantages: Side A is just a fingerprint collector and the texture is not good. The hard drive speed is poor. The continuous writing speed is only 50MB/s. The most important thing is that the screen brightness cannot be adjusted. I have to re-flash the motherboard bios.
Features of Lenovo computers
The microprocessor (or CPU) works together with the operating system to control the operation of the computer. It's like the brain of a computer. CPUs generate a lot of heat, so desktops use air circulation, fans, and heat sinks (a system of base plates, channels, and cooling fins that take away the heat generated by the processor) to cool the temperatures of various components. Since there is little space inside a laptop to use these cooling methods, its CPU typically: has a lower operating voltage and clock frequency - this produces less heat and consumes less power, but also reduces processing speed of the machine. Additionally, most laptops will run at a higher voltage and clock frequency when plugged into an external power source, and at a lower voltage and frequency when running on battery.
It is not installed on the motherboard through pins - the pins and sockets in desktop computers take up a lot of space. In some laptop motherboards, the processor is mounted directly onto the motherboard without the use of a socket. Other motherboards use Micro-FCBGA (Flip Chip Ball Array), which uses balls instead of pins. This design saves space, but in some cases also means that the processor cannot be removed from the motherboard for replacement or upgrade. Have a sleep or slowdown mode - The computer and operating system work together to slow down the CPU if the computer is idle or the processor doesn't need to be running fast. The Apple G4 processor also prioritizes data to maximize battery savings.
In addition to being beautiful and outward-looking, the outer casing also plays a protective role in the internal components of the desktop computer. The more popular shell materials include: engineering plastics, magnesium-aluminum alloy, and carbon fiber composite materials (carbon fiber composite plastic). Among them, the shell of carbon fiber composite material combines the low density and high ductility of engineering plastics with the rigidity and shielding properties of magnesium-aluminum alloy, making it an excellent shell material. The shell material indicated by general hardware suppliers refers to the upper surface material of the notebook computer. Engineering plastics are generally used for the hand rest and bottom.
Liquid crystal screen (LCD) notebook computers have used LCD screens as their standard output devices since their inception. They are generally classified into: STN, thin film transistor liquid crystal display (TFT), etc. Today's more excellent civilian-level LCD screens include SHARP's "Ultra Black Crystal" and Toshiba's "Low Temperature Polysilicon", both of which are thin film transistor liquid crystal display (TFT) LCD screens. removeThe light-emitting device of the LCD screen outside the screen is also very important. Poor-quality lamps will cause the color temperature deviation of the LCD screen to be very serious (mainly yellowing or redness).
Lenovo's computers use many new technologies, one of which is fingerprint recognition technology. Its principle is to use the fingerprint information of a biological finger to , converted into computer passwords. This technology actually belongs to file encryption technology. With this technology, users can use computers more safely and conveniently. It is precisely because of this technology that many people want to try such a magical thing. Technology has also attracted the attention of many consumers. In addition to fingerprint unlocking technology, its high-performance Core I7 processor is also a selling point. This processor can also be regarded as a high-end processor.
