When we use a notebook, we may encounter such a situation, that is, the battery of the notebook cannot be charged, which is a headache.
So what if the laptop battery doesn't charge?
Let's take a look at the repair method for notebook batteries.

When the battery of your favorite notebook does not charge:

With the use time getting longer, notebooks will have various problems. There is a phenomenon that the notebook can be used for a long time when it is disconnected from the power supply, but the battery can't be charged due to the long use time, leading to the notebook computer’s inability of being used without the power supply finally.
Why is this situation happening and how to solve it?

Cause Analysis:

1. Software Problems

Generally speaking, many computer brands, such as Dell, Lenovo, Sony, etc., will equip their notebooks with power management software during the production. If a certain "battery protection mode" is enabled, the power management software will prohibit the battery from charging and discharging after detecting that the user uses AC power, to prolong the service life of the battery.

Therefore, if you find that your notebook is not charged, you can first enter the relevant power management software, turn off the battery protection mode or tick off the charging prohibition option. If there is nothing wrong with the hardware, the battery can be charged later.

2. Hardware Problems

There are hardware problems with the battery itself. Generally speaking, we can judge by restarting the computer and reseating the battery. If the battery still can't be charged, you may want to install some hardware detection applications to get the approximate reference information of battery loss.

If a battery hardware failure can be determined, you’ll be recommended not to open it by yourself or try to repair it, because there will be certain risks. In this way, it is better to find someone professional to repair it.

The Windows7 Ultimate system will continuously discharge the notebook until the power is completely exhausted, and then the notebook will automatically shut down. At this time, we can connect the power adapter for charging, but don't turn it on. After the charging indicator light goes out, the whole process will be completed.
