The reason why the notebook cannot be charged
As a result, 0% of the available power has been connected but not charged, that is, it can not be charged. Most of the reasons are that the notebook battery is aging or not paying attention to maintenance. For example, many friends often use up the battery until the computer automatically turns off, which is easy to damage the battery.
In addition, some notebook computer users take out the battery factory area and put it unused. If the battery is removed and stored, it will also consume the battery, resulting in poorer battery life.
How to do if the notebook can't be charged
Method 1
First of all, remove the source of the fault, unplug the battery and turn on the power adapter only. If the power on normally means that the power adapter and the motherboard are OK. If the fault persists, it may be the problem with the power adapter or the motherboard. At this time, try to power on with the battery. If the battery and power adapter fail to boot smoothly for the same reason, it may be the laptop motherboard There's a problem.
We can turn on 'power options' and click' change schedule settings'.
Next, select 'change advanced power settings'.
In the new pop-up window, check whether you have selected 'prohibit charging'. If so, you can choose to modify it, and then click 'OK'.
Method 2
When you enter the BIOS when the laptop starts, you will usually find the 'start battery calibration' option in the power project, that is, 'start battery repair'. Generally speaking, this will first remind the user to connect the power adapter for full charging, and then a text will be displayed to prompt the user to disconnect the AC power supply, and the system will continue to discharge the laptop until the battery is completely exhausted. After that, the laptop will automatically shut down. We can connect the power adapter to charge, but do not turn on the computer. The whole process will be completed after the charging indicator light goes out.
It should be noted that the battery repair process of BIOS may take 5 hours, so be sure to operate when you do not need to use the laptop. If this still can't improve the state of the battery, it can only be said that the battery has gone back to heaven. You can send it for repair or buy a new original battery.
