How to repair laptop battery loss? Many children lament the short battery usage time when using laptop computers; or after a period of use, the laptop battery usage time is short. These are all caused by the loss of the laptop battery. So what are the several ways to repair laptop battery consumption? What is battery consumption and how to repair laptop battery consumption to make this book last longer. Loss of cells Any battery (including laptop) will have a design capacity, such as 4800mAh, 23Wh, these are the maximum capacity of the capacitor. In fact, the actual capacity is not that high at all, or it will become smaller and smaller after a period of use. For example, the battery is labeled 4800mAh, but it is actually only 4500mAh, so the difference between the two is battery consumption u003d (4800-4500)/48008100%u003d6.25%. There are many reasons for battery wear. When using, try to prevent the following situations: 1. The quality of the battery itself is poor, and the battery loss will increase after a period of use. 2. The charging voltage and current required by the battery cannot meet the charging requirements of the battery. 3. Long-term use in high or low temperature environments will also increase battery loss. 4. The battery has remaining power protection. Generally, the protection will be activated when it reaches below 3% , But sometimes the method used by users is to put all the power before charging, which is also wrong. 5. Frequent incomplete discharging, charging the battery when it is not in use, it will also cause loss to the power supply. 6. Non-standard plugging and unplugging of the battery, or long-term use of the battery under very humid conditions, long-term use of the power supply under electromagnetic radiation (the conductivity of the metal inside the battery). The most common way to repair the loss of the laptop battery is to repair the laptop battery. It is to charge and discharge the laptop. You can use small external software to monitor battery consumption (see below). It is normal for the battery to have a certain loss, and the new notebook pen is generally not stored for use. I want to analyze how to charge and discharge to repair the loss of the battery: 1. The easiest way: open the computer control panel-power usage plan, select all time parameters of the power option as never, and cancel the check of the alarm option. Unplug the power cord of the laptop, let the laptop automatically shut down (do not let the computer in the standby state during the shutdown process); then turn on the power for charging (don't turn on the power during the charging process), such as repeated three times, the laptop can be maximized Minimize the repair of battery consumption. 2. System method: Answer: First, restart the laptop. Press F2- to enter the BIOS of the laptop. B. At this time, the screen turns blue, prompt: plug in the laptop power adapter to charge, and then follow the prompts to connect the power adapter to charge the laptop (if the power adapter is plugged in, there will be no prompt); after the power is fully charged, there will be a break Turn on the prompt of the power adapter, at this time we disconnect the power, and the power of other laptops will automatically turn off. After c waiting for the power of the laptop and automatically shut down, we connect the power adapter and wait for the power to be full of power (don't turn it on, look at the charging indicator), then turn on the computer and charge it. At this point, we have done a complete battery loss repair operation, and we can also use the method on lumaster to check the battery loss and current capacity. In this system method, if someone cannot start the battery calibration, then use the simplest method. To sum up, the repair method for the loss of the laptop battery is to perform a deep discharge operation on the laptop. The number of deep charging and discharging of the notebook computer battery is limited, about 200 times. Therefore, the deep charging and discharging operation of this book cannot be performed frequently. Generally, it is recommended to be once a month. Hope this helps everyone.
