When charging for the first time, it is necessary to continuously charge the battery to 12 hours, and charge and discharge it three times in a cycle to fully wake up the new battery. 3. If the external power supply is used for a long time, it is best to take out the battery. Many friends have not noticed this problem. Not removing the battery when using the external power supply will not only affect the life of the battery, but also make the heat dissipation burden of the notebook computer heavier and shorten the life of the notebook computer. 4. Charge and discharge regularly. Even if the lithium-ion battery without memory effect has certain inertia effect, if it is not used for a long time, it will lose its activity and need to be reactivated. Therefore, if you don't use the computer for a long time (3 weeks or more) or find that the charging and discharging time of the battery is getting shorter, you should completely discharge the battery before recharging it, generally at least 1 time a month. It is best to turn off the laptop when charging, so that the battery is fully charged. Don't unplug the power supply in the middle of charging. Turning off the charging will shorten the charging time by more than 30% compared with turning on the charging, and can prolong the service life of the battery. It is best to use it after charging for 30 minutes. 6. Prevent exposure, moisture, chemical liquid erosion and short circuit between battery contacts and metal objects. The charge and discharge times of lithium batteries are generally no more than 800 times, and the service life will be shortened with each charge. It is recommended that you use an external power supply whenever possible. If the power supply needs to be plugged and unplugged many times during use, the life of the battery will be greatly shortened if the built-in battery of the notebook computer is not pulled out, because every time an external power supply is connected, it is equivalent to charging the battery once. Optimal setting of power management options For laptop users, we recommend using WindowsXP operating system. Of course, if the laptop configuration is too low to meet the minimum configuration requirements of WindowsXP, that is another matter. There are many reasons, the most important of which is that the power management of notebook computers is the most advanced in all computer operating systems at present, and it would be better if it were combined with Centrino platform. 1.6GHz Pentium-M only works at frequencies below 600MHz when the load is light. If your laptop supports Intel SpeedStep and AMD PowerNow? Or longrun technology of quanmeida, you must remember to install the latest driver to play a role. WindowsXP is automatic, and you can find a balance between performance and power consumption according to your own requirements. The optimal setting of power management that users can do. 1. Don't use a screen saver. 2. Select "Portable/Pocket" in the power plan, and set the following time reasonably according to your own needs. Everyone's situation is different, so it is not convenient to make rigid rules. Generally, the time to turn off the hard disk is set to be slightly longer than the standby time, so as not to affect the life of the hard disk. 3. Enter "Advanced" in the "Power Option" attribute and use the "Power Key" reasonably, which will bring you great convenience and improve the battery life. For example, setting "when the laptop is turned off" to "standby" can save electricity, which is very helpful to the privacy of private data after leaving the laptop for a period of time, and there is no need to wait for the restart time. For notebook computers using first-line manufacturers (such as IBM, Sony, Hewlett-Packard, Toshiba, etc.). ), they usually provide some better power management software and have some special functions: IBM's power management program can reduce the refresh rate of LCD screen; Toshiba Toshiba's power management program can directly shut down any equipment you specify in the case of insufficient power; Sony's special power management program can set the running speed of the cooling fan, and can also close the unused IEEE 1394 interface and memory slot to save power. Energy Saving of Hardware In the process of using notebook computers, we can mainly save energy on hardware as follows: 1. Reduce the brightness of laptop LCD screen. The LCD screen is a big power consumer in the notebook computer, so we can reduce the power consumption by appropriately reducing the brightness of the screen. Most laptops adjust the screen brightness by "FN+" or "F8" or "F9". There are usually eight brightness options, so the middle brightness is generally selected. 2. The notebook computer is designed with expandability in mind to facilitate the connection with other devices. So we will see that there are many expansion ports around the notebook computer to connect peripheral devices. As long as the layout is reasonable, of course, the more expansion ports, the stronger the expansion ability. However, each port needs power consumption, and too many external interfaces increase unnecessary power consumption and shorten battery life. The print port and serial port of notebook computer are rarely used by ordinary people, so it is recommended to disable them in BIOS. If your laptop has infrared function, please turn it off when not in use. Just disable it in Device Manager and turn it on if necessary. Now almost all computers have built-in modems and network cards, so it's best to turn it off and turn it on again when necessary. Many computers are equipped with wireless network cards. If it cannot be used temporarily, it is recommended to disable it, otherwise it will be in constant network search and consume unnecessary power. 4. Hard disk energy saving. Try to increase the memory capacity of notebook computer to improve performance and reduce the energy consumption of hard disk reading. If the memory reaches 5 12MB, using Windows XP system can disable virtual memory and avoid reading hard disk frequently. 5. Some notebook computers will adjust the energy-saving technology of CPU and other components in the BIOS. Check whether this function is turned on. Economical use in normal use, as long as we pay a little attention, we can reduce the power consumption of the battery. Let's summarize it for your attention in use. 1. Unplug the peripherals connected to the expansion port immediately after use, such as printers, scanners, digital cameras, mobile hard disks, USB floppy drives, etc. As long as these peripherals are connected to the notebook computer, even if they don't work, they will consume the power of the battery; 2. If the expansion card in PCMCIA slot is not used temporarily, it should be taken out immediately; 3. The optical drive of notebook computer consumes a lot of power, so you should take out the discs you don't need for the time being, otherwise you will read them intermittently, which will increase energy consumption. Smooth heat dissipation efficiency There is a close relationship between the heat dissipation and power saving of notebook computers, which is also determined by the heat dissipation mode of notebook computers. Notebook computers generally use the heat dissipation technology of temperature control fan combined with heat pipe, and the built-in heat dissipation fan will not start until it reaches a certain temperature. Once the air circulation in the notebook computer is not smooth, the heat of the heat pipe cannot be dissipated in time, which will lead to the non-stop operation of the fan. Since only the temperature-controlled fan inside the notebook computer will run when it reaches a certain temperature, we can pay attention to the following points to reduce the power consumption of the fan. 1. Try to use it in a well-ventilated or air-conditioned room. 2. Don't let sundries and dust block the cooling holes of the notebook computer. The inside of cooling pipes and fins should not be too dirty. The author once dismantled a notebook, and there was a thick layer of ash everywhere, which would lead to very troublesome heat dissipation. 3. When it is used at home or in the office, it is best to prepare a water pad with good heat dissipation effect below. I hope it can help you to make your notebook better radiate heat through the water pad! ! ! ! !
