Many people's notebooks have been used for a long time and found to be slower and slower. Notebooks are not as big as desktop upgrades. Many people tend to give up the old ones, don't rush to throw them! The system home introduces some methods for upgrading old laptops, but the method is simple and obvious. After two or three years, a laptop that is in good condition may appear to be old-fashioned. The aging of the device and the new system and new software that take up more resources make it start to slow down and even appear during use. problem. At the same time, the wireless network standards and equipped interfaces supported by old laptops have lagged behind, and the speed is much lower than the latest standard wireless network adapters and new interface speeds such as USB 3.0, which have gradually become the bottleneck of computer data transmission. Unlike desktop computers, laptops are not designed with much room for upgrades. They are not intended to allow users to upgrade significantly. Therefore, many users who have high performance requirements for computers are forced to purchase only one new computer. However, if the laptop is only an individual spare part that needs to be upgraded, then we can still do some partial upgrades. On laptops, a mini PCI-E slot is usually reserved for users to upgrade. With this slot, we can install an mSATA SSD as a system disk, taking full advantage of the advantages of SSDs and enabling the system to start and run faster without affecting the storage capacity of the device. It is also possible to install an adapter card with a high-definition decoder chip so that the old device can have enough performance to play HD movies. In addition, the hard disk, wireless network card, memory, mobile communication adapter and other modules on the laptop are usually installed in the slot. For these modules, we can adjust according to our own needs. For example, we can replace a wireless network. The adapter card allows the laptop to support the latest wireless networking standards. And which module should be replaced, and what device should be left to the mini PCI-E slot, we need to decide according to the bottleneck of the laptop and its own application needs. The following CHIP will introduce various upgrade methods for your reference. Limitations of upgrading laptops It is easiest to upgrade with a mini PCI-E slot, and replacing the original modules of the laptop is relatively difficult, which is a problem we must consider when deciding on the upgrade method. In general, the motherboard and graphics card of the notebook computer can not be replaced, and most of the processor can be replaced, but if you want to replace the processor, you need to carefully check the information of the notebook manufacturer, in addition to determining the processor that the motherboard can support. Beyond the type, we must also consider the heat generated by the new processor, whether the notebook's cooling system can withstand the problem. The upgrade steps are from easy to difficult. Below we will introduce the method of upgrading and installing various modules. Generally speaking, because upgrading the internal modules requires the laptop to be opened, the difficulty is relatively high. 1. Installing a USB 3.0 adapter card The slow USB 2.0 interface is awkward when transferring large files. It causes us to be unable to transfer data using USB 3.0 devices that are now available everywhere, and to solve this problem in laptops. Installing the USB 3.0 adapter card on the Express Card slot is the only way. USB 3.0 Express Card usually provides two USB 3.0 interfaces. Depending on the channel and brand of the product, the price is mostly between 50 and 150 yuan. Pay attention to the preferred 34mm card when purchasing the USB 3.0 adapter card for Express Card, because the 34mm Express Card can be used in the 34mm and 54mm Express Card slots, otherwise you need to figure out the size of the Express Card slot on the notebook. The Express Card is easy to install, insert the card into the slot and install the driver provided by the manufacturer. 2, increase memory If the notebook's memory is less than 4GB, then upgrade to 8GB is necessary. Use CPU-Z (www.cpuid.com) to check the memory capacity, model (“memory' tab) installed on the current laptop, and whether there are free slots (“SPD”tab). Next, according to the original memory situation, consider buying a higher capacity memory to replace the original memory or installing a memory module in the free slot with the same original memory. Locate the screw with the memory module logo on the back of the notebook and unscrew the screw to open the bezel to see the memory slot. Press the metal tabs on both ends of the memory module to open the fixture and remove the memory, then perform the reverse steps to install the new memory. 3, install SATA solid state drive For all laptops that use mechanical hard drives, installing a solid state drive can effectively improve performance, operating system and application startup speed will be much faster. There are two options for installing a solid state drive. One option is to replace the mechanical hard drive with a solid state drive. The hard drive is usually mounted close to the bottom of the laptop, so you can open the hard drive cover on the bottom or side of the laptop and easily remove the hard drive for replacement. Then, just install the SSDs in the reverse order. Next, we can install the original hard disk to the mobile hard disk box to copy the required data from it. However, in order to get the best performance, CHIP does not recommend copying the original operating system, but should reinstall the operating system on the SSD, so that the new version of the Windows installer will be able to automatically adopt the SSD after identifying the SSD. Optimized settings allow SSDs to maximize performance and extend the life of SSDs. 4. Install the mSATA SSD to upgrade the SSD for the old laptop. In addition to using a SSD to replace the mechanical hard drive, in the case of a laptop with a mini PCI-E slot, you can also consider the mini PCI in the laptop. Install an mSATA solid state drive on the E slot. The installation of mSATA SSD is very simple. Just open the slot cover on the bottom of the laptop and insert the mSATA SSD into the slot. However, it should be noted that the mSATA SSD must be fixed to the mini PCI-E slot by a small screw, but some laptops do not have the appropriate screws reserved. Some mSATA SSD products are not equipped with screws, so they are purchasing Before we must first find out whether there are reserved screws on the slot, if not, you need to consider the screws when purchasing the mSATA solid state drive. After installing the mSATA SSD, set the priority to use the SSD boot in the BIOS, and reinstall the operating system and applications on the SSD, then store the photos and various video and audio files on the mechanical hard disk to make full use of the SSD. Performance and capacity of mechanical hard drives. The performance of mSATA SSDs is close to that of SATA SSDs. In our tests, the Samsung 840 Evo mSATA SSDs performed very well. 5, install high-definition accelerator If the laptop can not play HD video smoothly, or rely too much on the processor during playback, seriously increase the load of the cooling system, affecting the battery life, then installing a high-definition accelerator will be an effective method. Broadcom's Crystal HD chip is the current mainstream solution, and its latest version is BCM-70015, which is equally effective for Flash HD video decoding. Through online trading venues such as Taobao, we only need to spend about 100 yuan to buy a mini PCI-E HD accelerator equipped with BCM-70015 chip. Just insert the mSATA SSD into the mini PCI-E slot and install the 32-bit or 64-bit version of the driver depending on the version of the operating system. Usually, Windows Media Player will automatically use the chip to decode HD movies, but if the player fails to do so, we can manually select Broadcom's video decoder in the Windows Media Player Settings & Options dialog box. And if you want to speed up the decoding of Flash HD video, then we need to reinstall Adobe Flash after installing the Broadcom driver. 6. Replace the wireless network adapter card If the wireless network speed is the bottleneck of the laptop, then we can consider replacing the wireless network adapter card. In general, the laptop's wireless network adapter card is installed through the slot, and most of them only need to remove the baffle on the back of the laptop to replace it directly. Therefore, simply remove the old card, install the new card, and update the device driver. However, during the replacement process, special attention should be paid to the antenna of the wireless network adapter card. The newer standard wireless network adapter card usually requires at least two antennas, and the wireless network adapter card on the old laptop may have only one antenna. Antenna, this will require us to proceed with the next step of the upgrade. 7. Adding a wireless network antenna If the notebook computer has only one wireless network card antenna, it may not work stably and use the 5GHz frequency band after replacing the new wireless network adapter card, which will seriously affect the speed and stability of the wireless network. Therefore, in this case, users with certain hands-on ability can consider installing a wireless network antenna. First, select the appropriate antenna according to your choice of wireless network adapter card, then open the display and bring the antenna to the back of the display so that the antenna can be in a higher position when the notebook is turned on. Get a better signal. Each laptop has a different way to open the display. For example, in the Lenovo X201, we must unscrew the 3 screws on the lower edge of the display and release the panel and display frame to open the display. The connection of the antenna can be adjusted according to the direction of the display wiring, and the antenna is led to the laptop and inserted into another antenna connector of the wireless network adapter card. This series of operations requires us to have some hands-on ability. CHIP recommends searching and learning the screen disassembly method of the laptop used by the Internet before the actual operation to ensure that the operation can be completed smoothly.
