How to charge a laptop battery?
In fact, when a laptop battery is fully charged, it basically only lasts about two hours. How to make good use of the laptop battery, how to extend its use time and use Issues such as lifespan are undoubtedly a problem that plagues the majority of notebook computer users.
So, what should I do if the battery cannot be charged?
How to charge the laptop battery
1. Unplug the power supply after it is fully charged
When the laptop battery is fully charged, the laptop should not be used with an external power source. Because when the laptop is used with the battery loaded, the battery is actually in a state of repeated charging at this time. In addition to reducing the life of the battery, using AC and batteries at the same time will also cause the machine to overheat and easily damage other components.
2. Not using the battery for a long time
Although the battery should not be used when connected to an external power supply, it is also wrong not to use the battery for a long time. The battery capacity needs to be activated regularly. Appropriate use appears more accurate. In particular, you should pay attention to charging the battery after it is used up every time, and try not to unplug it when it is not fully charged. After it is fully charged, you should use the battery or the power adapter alone, not both together.
3. Remove the battery frequently
Do not remove the battery frequently and expose the battery compartment. Doing so can easily get a lot of dust into the battery and cause poor contact during use. When disassembling the battery, you should Pay attention to dust, water, moisture and shock, and clean the warehouse regularly with a small brush.
What should I do if my laptop battery cannot be charged?
Solution 1: Use software to refresh the battery.
IBM notebooks provide a "Battery MaxiMiser and Power Management" software. Through this software, we can have a good solution to incorrect battery capacity display and reduced battery life. Run this software, and the computer will automatically calibrate and discharge the battery based on the battery's status. When the program ends, you can find that the gap between the actual capacity and the design capacity of the battery will become smaller (but still exists).
Solution 2: Use firmware to refresh the battery.
Some laptop manufacturers have embedded the battery correction program into the BIOS firmware (such as ASUS). We only need to enter the BIOS to execute the battery correction program when booting the computer.
Solution 3: Replace the battery or deeply discharge it.
If the battery has problems due to the aging of the battery cells, we can only solve the problem by replacing the battery cells or deep discharge, but these actions may cause the battery to malfunction. Damaged or unusable, so please be careful before handling.
