Laptops are an indispensable part of modern life, but sometimes we encounter some annoying problems. One common problem is that the laptop cannot charge even though it is plugged in. This usually happens when the laptop has already indicated that the battery is low, which catches people off guard.
As we all know, laptop batteries generally use lithium-ion batteries. If they are charged frequently for a long time, the battery will be damaged. Or if you only rely on an external power adapter to use the laptop from the beginning, and never use the built-in battery alone, it will shorten the battery life and even cause failure. After confirming that the battery has no deformation, you can try to disconnect the battery cable and reconnect it, or go to a regular store to activate the battery (usually free of charge).
Recently, my Lenovo Legion laptop also encountered a similar situation, so we summarized some repair methods that can be performed by yourself, hoping to help everyone solve this problem.
Check the laptop battery
Physical inspection
When troubleshooting any electronic device, the first step we must always remember is to check the most basic factor: power.
Many times, we overlook power issues, especially when using multi-purpose sockets or charging ports. For example, some power strips have independent switches. If the switch is turned off, the device will not be powered. Or, the charging port may have poor contact, which can also cause the device to not charge properly.
Take a laptop for example. When the battery shows that it cannot be charged, we must first check the external reasons, make sure that the power adapter is working properly, the socket is powered, and confirm that the power cord is firmly connected .
Only after solving these most basic problems can we further troubleshoot the problem.
Software Troubleshooting
Many computer brands develop power management software for their products, which includes a “battery protection” mode. When the power management software detects that the laptop is connected to a power source, the program will prohibit charging the battery in order to extend the battery life. This “battery protection” mode is designed to reduce the number of battery charge and discharge cycles, thereby extending its life.
However, this mode may also cause the user to be unable to charge the laptop while using it, causing inconvenience to the user. In order to restore the charging function, the user can enter the power management program and turn off options such as the “battery protection” mode or the “charging prohibition” mode.
When the laptop is plugged in, the screen displays “Battery 0%, plugged in, not charging/charging”, which usually means there is a problem with the driver.
Drivers are the bridge between the hardware and the operating system, and they are responsible for managing the operation of the hardware. When there is a problem with the driver, the laptop may not recognize the battery, resulting in failure to charge.
Hardware troubleshooting
First, check your original power adapter. It may be the culprit. Long-term use can cause the adapter to malfunction and affect charging efficiency. Try charging your laptop with another adapter. If it charges normally, then the problem is with the original adapter.
If your laptop supports USB-C charging, you can try using another adapter that supports USB-C charging . If the problem persists after changing the adapter, you need to consider other hardware problems. For example, the laptop’s charging port may be damaged. Or, the battery inside the laptop may be aged or damaged and cannot charge properly.
Steps to Fix a Laptop Battery That Won’t Charge
Replace or repair the power adapter
If it is determined that the problem is with the power adapter, we can try to replace it with a compatible power adapter for charging. If the power adapter is only slightly damaged, you can also consider repairing it. It may be a simpler option to directly replace it with a new power adapter, so that you don’t have to worry about using a slightly damaged adapter for fear that it will suddenly fail one day. Of course, it is recommended that users compare the price of the new power adapter with the repair cost in order to make a wise choice.
Replacement battery
If the battery is old or the internal circuit is seriously faulty, you need to replace it with a new one . If your laptop battery is still under warranty, that’s good news, which means you can get free repair services. Please don’t hesitate to contact after-sales technicians. They will determine whether the battery needs to be replaced based on your specific situation. If your computer has been with you for many years, you may face additional costs and troubles when it needs a battery replacement or repair.
Although replacing the battery yourself may save some money, it may bring risks and uncertainties. Choosing official repairs, although more expensive, at least guarantees quality and service. This does not mean that replacing the battery yourself will definitely lead to adverse consequences.
In fact, many users choose to buy batteries for replacement on their own. They do not need to worry about whether they have the necessary tools and detailed tutorials, because the merchants will provide everything, and there is also a free warranty after-sales service guarantee. When buying a new battery, be sure to choose a formal channel and a well-known brand to ensure the quality and safety of the battery.
Update software or drivers
If the battery cannot be charged due to software or driver problems, we can try to update the operating system, power management software, and related drivers. Before updating, be sure to back up important files and data. During the update process, unexpected situations may occur, resulting in data loss. Backing up data can effectively prevent data loss and ensure the security of important information. Updating the operating system can fix system vulnerabilities, improve system performance, and may solve battery-related software problems.
