label: The reason why laptops are so popular is because laptops are equipped with batteries and can be used for five or six hours without power. However, laptop batteries need to be charged after they are used up, but many people find that when charging their laptops. If you don't have access to electricity, let's take a look at how to do if the laptop battery is not charged. The reason why the laptop battery is not charged 1. First of all, many computer brands will provide power management software for their notebooks. If some kind of “battery protection mode†is enabled, the software will prevent the battery from being charged and discharged after detecting that the user uses AC power to extend battery life. Therefore, if you find that the notebook is not charging, you can first enter the relevant power management software to turn off the battery protection mode or tick off the prohibition charging option, if the hardware is no problem, you can charge. 2, Secondly, the battery's own hardware failure, usually can be used to restart the computer, re-plug the battery to determine, if the battery is still unable to charge, may wish to install some hardware detection applications, get the approximate battery loss reference information. If it is determined that the battery hardware is faulty, do not open it or try to repair it yourself. There is a certain risk. Do not blindly believe that some so-called small tricks may cause the battery to catch fire or even explode. What should I do if my laptop battery does not charge? 1. Use the software method to refresh the battery: You can use a computer optimization software or hardware detection software to perform a comprehensive check on the computer. These software will automatically check and discharge the battery according to the state of the battery. When the program ends, you can find the battery. The difference between actual capacity and design capacity will be smaller (but still exists). 2. Use the firmware method to refresh the battery: Some notebook manufacturers embed the battery correction program into the BIOS firmware (such as ASUS), as long as they enter the BIOS to perform the battery correction program at boot time. The way to use the firmware is to use the BIOS, enter the BIOS interface at boot time, and then correct the battery program in the BIOS. 3, replace the battery or deep discharge: For some of the battery chips that have a long time, there is a problem, you can replace the battery chip, but in the process of replacement should be careful, but also can be repaired with deep discharge, of course The method is risky, and these behaviors can cause the battery to be damaged or unusable. What are the misunderstandings of laptop batteries? 1. Misunderstanding 1: The notebook lithium battery is exhausted when it is used. In fact, excessive charging and discharging of lithium batteries will rapidly reduce the activity of the battery, so do not deliberately charge to 100% during use. 2, misunderstanding 2: as long as the shutdown power can also be placed on the bed. In fact, this is easy to cause the battery to overheat and catch fire. Therefore, you should try to avoid placing the computer on a sofa, bed, etc. where it is not easy to dissipate heat. 3. Misunderstanding 3: The laptop never removes the battery. In fact, the problem of overcharging does not exist for a well-designed lithium battery because the lithium battery has a protection circuit. 4. Misunderstanding 4: Fully charged and still connected to the power supply to continue to use. In fact, in addition to causing a reduction in battery life, the simultaneous use of AC and battery can cause overheating of the machine and damage other components. 5. Misunderstanding 5: The battery should be fully charged or placed in photoelectric storage. In fact, the notebook lithium battery should be activated regularly, whether it is fully charged or discharged, the correct method is to discharge about 30 ~ 40%.
