Several reasons for not charging the battery into the notebook

Check for software problems

In general, many computer brands such as Dell, Lenovo, Sony, etc., will be equipped with their own notebook power management software. If some kind of "battery protection mode" is enabled, the power management software can prolong battery life by detecting that the user uses AC power to prohibit battery charge and discharge.

So, if you find your laptop is not charging, you can go to the relevant power management software, turn off the battery protection mode or check out the Forbidden charging option, if the hardware is no problem, the battery will be able to charge.

The hardware itself is problematic

The battery's own hardware failure. In general, we can use the restart computer, reseat the battery to judge, if the battery is still unable to charge, may wish to install some hardware detection applications, to obtain the approximate battery loss reference information. If it is determined that the battery hardware failure, do not open or try to repair, there is a certain risk, do not blindly believe that some of the online so-called tips, may cause battery fire or even explosion.

How to fix it safely

When the laptop is booted into the BIOS, the "Start battery calibration" option, "starting battery repair," is usually found in the power project. Generally, this will first remind the user to connect the power adapter for full charge and then display text prompting the user to disconnect the AC power, and the system will continue to discharge the notebook until the battery is completely depleted. Since then, the notebook will be automatically shutdown, we can connect the power adapter to charge, but do not boot, the charging indicator is off after the whole process is completed.

It should be noted that the BIOS battery repair process may take 5 hours, so be sure to do it when you do not need to use the notebook. If the move is still not improving the battery state, then you can only say that the battery has been beyond resurrection, you could either repair or buy a new original battery.
