The laptop can t be charged in, why can t the laptop be charged?

1. Software problems, generally speaking, many computer brands will equip their laptops with power management software. If a certain Battery Protection Mode is enabled, the power management software will prohibit the battery from charging and discharging when it detects the user's use of AC power, thereby extending the battery life. Therefore, if you find that your laptop is not charging, you can first enter the relevant power management software, turn off the battery protection mode or check the no charging option, if there is no problem with the hardware, the battery can be charged;

2. The hardware failure of the battery itself. Generally speaking, you can use restarting the computer and replugging the battery to tell if the battery still won't charge, you may want to install some hardware detection apps to get an approximate reference information about battery loss. If it is determined that the battery hardware is faulty, do not open it by yourself or try to repair it, there is a certain risk, do not blindly believe some so-called tips on the Internet, which may lead to the battery**even**;

3. If it is a hardware failure, it is recommended to send the laptop to the repair shop for after-sales maintenance testing, and if it is a replaceable design, a new battery can be replaced;

It's better than charging it basically, so how about taking a look at the charger? Don't need to change a charger?

If the battery power increases, it means that the battery is over-discharged, and it can be charged in time.

If the battery level is still 0 after charging for a long time, it may be a battery failure and it is recommended to send it for repair.

The laptop has a noisy function in the battery option, such as "disable charging", under this function, the adapter directly supplies power to the laptop without charging the battery, in which case it cannot be charged. It is recommended to check the battery options to see if the charging function of the notebook is disabled, of course the win8 system is slightly different.

If the charger is not the original charger to charge the computer, sometimes the computer display link can not be charged, if this situation is recommended, it is recommended to use the original charger to charge the computer, and you can buy it if you don't have it.

In the battery options, click on the display plan used by the computer in the display plan, as shown in the figure below, click to change the advanced power settings, check whether the power supply is used, of course, some computers have a display plan for maintaining the computer, and selecting this letter plan will also appear that the power supply has been connected and does not slip into the slag charging.

1.The laptop charger is damaged. In this case, changing the charger can solve the problem.

It can't be charged, and the power won't be off. In this case, there is no problem with the charger. It is likely that there are a few problems with the following.

But he's charging.

There is no change in charge percentage.

If charging is displayed, but the charging percentage does not change. There was also no significant power loss. Then there are the following questions.

Hello! According to your problem description, the first factor is that there is a problem with the connection between the laptop's power cord and the computer, such as poor contact, which is also a very common problem. The reason for this question is that it is not used properly, such as excessive force in the process of unplugging and plugging in the power supply, resulting in serious damage to the charging port, and the solution is to replace the charging port, or pad it every time you plug in the power supply.

The second reason why the laptop battery is faulty and the power light below flashes red is that the laptop battery has a problem, after all, for users who often use laptops, they all know that the battery is a hard injury, and the battery can't be charged after an average of three years, and the final result is that the battery is directly broken. However, due to battery failure and can not be charged, the computer is prompted, look at the computer's power light, under normal circumstances, the power light is white and always on, and after the battery failure, the power light shows a red light or orange light has been flashing. If there is a problem with the power adapter, you need to check it in time, and the laptop cannot be charged, sometimes it is not necessarily the fault of the computer, and the power adapter may also be broken.

At this time, what we have to do is to check, first see if the light of the power adapter is still on, if it is plugged in and it does not light up, then it is 100% that the adapter is broken. At the same time, you should also test the temperature of the adapter by hand, under normal circumstances, the adapter is warm, if it is cold, it proves that the adapter is not energized. Computer software problems, the fourth factor that opens the function of battery protection mode, is the software problem of the computer, some computer guard software is the same as the software on the mobile phone, and the battery protection function will be automatically turned on, and even some brands of laptop wheels come with battery protection function, in this case, the battery protection function will be charged reasonably according to the current voltage and the remaining power, if it is detected that it does not need to be charged, at this time, even if it is plugged in, it will not be powered on, If you don't want to use this function, you can just turn it off in the background.

Hello dear, glad to answer for you, there may be several reasons why the laptop won't charge:1Power Adapter Failure:

The power adapter is the bridge between the laptop and the outlet, and if the adapter itself fails, then charging will naturally not work. 2.Battery aging:

After a long period of use, the life of the battery will gradually decay, and if the battery has reached the end of its life, then it can no longer be recharged. 3.Charging line failure:

The battery needs to go through the line and control circuit to manage and distribute the charging current and voltage during the charging process, and if the line is faulty, then it cannot be charged properly. 4.Power Management System Abnormal:

If the battery management system is not connected with the battery or other reasons, the battery cannot be charged. The above is the original cause of common laptop charging problems, which need to be troubled and solved according to the actual situation.
