Remove the screws and open the host panel. We can use a hair dryer or vacuum cleaner to blow away most of the dust on the edge of the chassis. The remaining dead corners can be wiped carefully with an electric toothbrush.
I don’t recommend using a hair dryer in the position of the fan, because there is a lot of dust inside the fan. If you use a hair dryer rashly, it is likely to fly dust all over the place, so using a vacuum cleaner is the most appropriate choice. Then use an electric toothbrush to polish it to clean out some strongly attached dirt, and continue to use a vacuum cleaner to clean it. This kind of cleaning effect completely beats air blowing
I have a Lenovo B450, the basic configuration: CPU is Celeron T3100, memory 2G, integrated display 512m.
I should have bought this phone six or seven years ago. It is already very old. It often freezes after about a minute of being turned on.
For the win7 system, I tried my best to protect it, even reinstalling it was useless.
Considering that the mechanical hard drive is aging and other hardware cannot keep up, we finally upgraded with the attitude of treating a dead horse as a living horse.
First use CPU-Z to query the motherboard information. I decided to use P8800 for the CPU. I originally wanted to use T9300 or T9500, but I was afraid that the notebook’s cooling system would not be able to keep up and the temperature would be too high. Add one more 2G memory, for a total of 4G. Buy a 30G solid state drive to install the system. Except for the solid-state drive, all the above are new and cost about 120 yuan (plus optical drive bracket).
The CPU and memory are both in stock, and the price for both items on TB does not exceed 100 yuan.
Disassemble the machine, clean it, re-apply heat dissipation grease, install the machine, and install the system. Now it only takes 13 or 14 seconds to boot up, surfing the Internet, watching movies, office software, CAD, etc. run smoothly. The total cost of the above is about 220 yuan. The above is for reference only. If you want to mess with it, you must know the knowledge of hardware installation and system installation.
You can buy a 2GB memory directly. After installation, the memory will be expanded to 4G. Upgrading the graphics card is much more troublesome. Your machine's graphics card is directly welded to the motherboard. If you want to replace the graphics card, you can only replace the motherboard together. Memory can be bought for tens of dollars.
You can clean the heat dissipation yourself, or you can choose a professional store. There are detailed graphic and textual explanations for cleaning laptops online. When I dismantled the machine in a professional store, the price was 50, but it wouldn’t be much different elsewhere.
There are many factors to consider, including budget, performance requirements, personal preferences, etc. The following are some common upgrade methods:
Memory upgrade: Memory is an important part of computer performance. Upgrading memory can improve the computer's running speed and multi-tasking capabilities. It is recommended to choose memory modules with the same frequency and capacity to ensure compatibility and stability.
Hard drive upgrade: The hard drive is an important part of the computer for storing data. Upgrading the hard drive can improve the computer's storage capacity and reading and writing speed. It is recommended to choose a hard drive with the same or larger capacity to ensure compatibility and stability.
Graphics card upgrade: The graphics card is an important part of the computer’s graphics processing capabilities. Upgrading the graphics card can improve the computer’s graphics processing capabilities and game performance. It is recommended to choose a graphics card with the same or stronger performance to ensure compatibility and stability.
CPU upgrade: The CPU is the core component of the computer. Upgrading the CPU can improve the computer's running speed and multi-tasking capabilities. It is recommended to choose a CPU with the same or stronger performance to ensure compatibility and stability.
It should be noted that upgrading hardware requires consideration of multiple factors, including budget, performance requirements, personal preferences, etc. It is recommended to conduct sufficient research and comparison before upgrading to choose an upgrade plan that suits you.
If you want to wholesale computer hardware, you can consider the following ways:
1. Electronic product wholesale markets: These markets usually gather many electronic product wholesalers to provide wholesale services for various computer hardware. For example, Huaqiangbei Electronics Market in Shenzhen, China, Zhongguancun Electronics Market in Beijing, etc. In these markets, you can find many hardware wholesalers with more varieties and prices, but you need to pay attention to product quality, after-sales service and other issues.
2. Online e-commerce platforms: Such as Taobao, JD.com and other e-commerce platforms. There are many sellers on these platforms providing wholesale services of various computer hardware. You can use these platforms to find corresponding sellers and contact them to compare prices and quality, and choose the wholesaler that suits you best. It should be noted that you need to pay attention to the authenticity of the product and after-sales service issues.
3. Contact the manufacturer directly: If you want to customize hardware with special specifications, or purchase hardware of a certain brand in large quantities, you can contact the manufacturer directly for wholesale. This way you can get better prices and after-sales service, but you need to pay attention to the credibility and strength of the manufacturer.
It should be noted that no matter which way you wholesale computer hardware, you need to pay attention to product quality, after-sales service and other issues. Only by choosing a regular and reliable wholesaler can you ensure product quality and after-sales service.
Commonly used methods are as follows:
1) Direct observation method: Inspection by touching with hands, seeing with eyes, hearing with ears, etc. Hand touch: The normal temperature of the shell of general components is between 40°C and 50°C. Except for the CPU that requires a fan to cool down when the temperature is high, other components should not be hot under normal circumstances. Visual inspection: Check whether the connectors and jumper pins on each control board and card are inserted upside down, loose or short-circuited, whether the data cable is plugged in place or correctly, and whether the function selection switch is set correctly. Listen: Listen for any abnormal sounds when turning on or running. For example, if you hear a long "beep-beep" sound when you turn on the computer, it means that the memory module is not inserted properly, or there is a problem with the memory module. For example, if you hear a "beep-beep" sound when you power on, "One is long and the other is short, that is because the graphics card is not inserted properly. If a problem is found, it should be shut down immediately for maintenance.
2) Plugging and unplugging method: This is a method of identifying faulty components by unplugging and plugging in some plug-in boards in the machine. After each piece is pulled out, turn on the machine and check the status of the machine to find out the fault. If there is no fault display during startup, you can also unplug all plug-ins and peripherals first, leaving only the motherboard and graphics card. If the startup is normal, then plug in various boards and peripherals one by one to check until the crux of the problem is found. .
1. CPU test software, it is recommended to use SUPERpi, or the chess master test program, and the detection software is recommended to use CPU-Z
2. Memory test: memTest, this is currently recognized as a better test software
3. Power supply test: OCCT, this is of course also recognized
4. Graphics card: Of course it is the 3DMARK software, the most recognized testing software in the industry is this software
