With the progress of the times, notebook computers have become a common tool in people's lives, and are favored for their portability and convenience. When using a notebook computer, the battery is particularly important as a key component of battery life. However, when there is a problem with the laptop battery, how should we solve it? Here are three common battery failures and how to fix them:
The system shows that the power is 0%
There are usually two possible causes for a battery that is charging normally but the system shows 0% charge. First of all, after replacing the new batteries, the battery board may not be able to correctly identify the power, resulting in the display always being 0%. This can be caused by incompatible cells or a faulty battery board, and the solution is to replace it with a new battery.
Another possibility is that the battery's internal metering circuit is malfunctioning, resulting in inaccurate display and charging. In this case, the battery also needs to be replaced. Since the laptop battery is usually a closed design, internal faults cannot be repaired, and the problem can only be solved by replacing the entire battery.
When encountering the situation that the battery display is always 0%, it is recommended to try to reinstall the battery first to ensure that it is well connected. If the problem persists, then replacing the battery with a new one is the only way to solve this problem. When purchasing a new battery, choose a model that is compatible with the original battery, and be sure to buy a reliable product.
Automatic shutdown when running on battery power
When the notebook computer automatically shuts down when using battery power, it is probably caused by the battery overheating. Modern laptops are often equipped with protection circuits to protect the battery and device from damage caused by excessive temperatures and excessive discharge currents. When the battery temperature exceeds the safe range or the discharge current is abnormal, the protection circuit will trigger automatic power-off.
In order to prevent the battery from overheating, there are several points to pay attention to. First, make sure your laptop's air vents are clear and unblocked. Blockage of the vents can restrict air flow, causing the battery and other hardware to heat up. It is a good habit to regularly clean the vents to remove dust and debris.
Secondly, try to avoid long-term high-load operation. Continuous use of high-performance tasks and large applications will generate more heat and increase the risk of battery overheating. For heavy workloads, consider using a proper cooling pad or cooling base to help dissipate heat.
Also, don't place your laptop on a soft surface, such as a bed or sofa, as these can hinder heat dissipation. Using a hard board or thermal pad as a support surface can provide better airflow. battery won't charge
When the battery is fully charged and has not been used for a long time, when you want to charge it again, you find that the battery cannot be charged and there is no remaining power. This may be due to passivation and deactivation of the battery due to long-term idleness. You can try to find a professional to discharge the battery and then charge it; if the problem persists, it is likely that the battery has been damaged and needs to be replaced with a new one.
Also, buying a low-quality laptop can also lead to battery problems. When buying a laptop, you should choose a regular sales store and carefully select products with reliable quality.
In short, laptop battery failure is a common problem, the above reasons are only part of the situation, more complicated problems may need to seek professional help. In daily use, reasonable maintenance of the battery, avoiding over-discharge and overheating will help to prolong the service life of the battery.
