Correct charging method

For the new laptop just bought back, because the manufacturer has charged it for the first time during the test, the battery should have 3% of the power when it is started for the first time. At this time, do not use the external power supply immediately, but use the remaining 3% of the power until it is turned off, and then charge it with the external power supply. Do not start the laptop when charging. The charging time must exceed 12 hours, Until it is fully charged (for example, unplug the power adapter after it is fully charged, and then recharge it after the battery is discharged at one time. Repeat it three times to activate the maximum potential of the battery.

In daily use, you should try to reduce the number of times you use the battery. Because the number of times you charge and discharge the laptop battery is limited, the battery life will be reduced once you charge it. Therefore, if you use an external power supply, you should remove the battery. If you often plug and unplug the power supply many times a day, and the laptop is equipped with a battery, the damage to the battery will be greater, Because each time the external power supply is connected, it is equivalent to charging the battery once. In addition, the notebook battery has a memory effect. Partial charging (less than 100%) will lead to inconsistent chemical properties of the battery cells, which will degrade the battery performance. Therefore, the battery must be recharged after the power is exhausted (the power is less than 1%), which is the best way to avoid the memory effect. Otherwise, the battery will easily lose its power supply capacity temporarily.

The laptop battery has been used for a long time. It is often under charged and even shows battery damage. For example, the standard battery life could have been up to 4 hours, but the battery life after charging is less than 40 minutes. It can be recovered as long as the battery is discharged. First disable the screen saver of the system, then enter the "Power Options" attribute interface, set the "power plan" to "high performance", then click "change plan settings", set all options under "battery" to "never", and finally enter the "advanced power settings" to set the battery power alarm prompt, such as the alarm when the battery power is lower than 5%.

At this time, adjust the screen brightness to the maximum, confirm that all program windows are closed, and save all previous working data. After confirming that the battery is charged at more than 80%, unplug the power supply and all external devices for discharge. After discharge, the laptop will automatically shut down, and then plug in the power supply to charge the laptop. This process can be repeated for 2 to 3 times. The purpose is to make the battery discharge continuously with low current, This discharge state is impossible to achieve in our daily use, and its effect is basically consistent with those special discharge software. If the power management attribute has no alarm operation function, we need to use the highest intensity artificial discharge operation at this time. The method is to enter the BIOS setting to turn off the power management function, that is, set "powerswitchmode" to "off", because many laptops have a power-saving mode. When the power is too low, they will automatically shut down. After saving the settings, restart the notebook, and press the pause key to stay in the windows screen before entering the system, Power off until the battery is exhausted, and charge it after 3 times.

Battery management tools

When the battery is powered on, sometimes we are dealing with important files. If the laptop battery suddenly runs out of power, it is an embarrassing thing. In serious cases, it may also cause the loss of important data. However, the laptop will provide power management software, which often also provides an alarm function, allowing users to set up a reminder mode when the battery is low or seriously low. For example, with the built-in power manager of ThinkPad notebook, after running the software, the user can select "enable low battery power alarm" in the "global power settings" window, and then set the battery power supply to drop to a certain period of time (such as 10%). When the battery life is only 10%, the system will sound an alarm to remind the user to save the data as soon as possible, so as to prevent the laptop from suddenly powering off when the battery runs out, Let unsaved work go to waste.

Notebook battery is a consumable accessory. The longer the service time and discharge times, the shorter the endurance time and service life. Therefore, for business users, the daily maintenance of notebook battery is also very important. ThinkPad power manager provides battery data viewing and battery maintenance functions. In the "battery information" window, the battery health status, voltage, temperature, retention capacity, remaining time Charging times and other information, so that users can reasonably carry out daily maintenance. For example, the health status is displayed in red, indicating that the battery life is about to expire. Please replace the battery in time, while yellow indicates that the battery has partially aged, and users should pay attention. In particular, it is necessary to mention the charging times. For convenience, many users sometimes connect to the power adapter when the battery is installed. Each time they plug in the AC, the battery will be automatically charged. The more such cases occur, the more the battery is charged, which seriously reduces the battery service life. In order to facilitate the user to charge and discharge the battery, the software provides the battery charge and discharge limit function. The method is to click the "battery maintenance" button, Then select "custom" under "charging valve". At this time, you can set when to charge and discharge the battery. For example, if you do not want to remove the battery because of trouble, you can set "start charging when it is lower than the following value" to less than 10%, so that the battery will not be charged even if it is connected to AC.
