Is it a hardware problem that the computer won t charge

1. Check whether the laptop battery is installed correctly. Is it because of the poor contact caused by the incorrect installation of the battery, so that it cannot be charged.

2. Secondly, if there is no problem with the installation, it is recommended that you check whether the metal splice and contact on the battery and battery slot are normal, whether the spring contact is pressed and does not bounce up, whether the metal splice is attached to the surface of the insulating substance, whether there are signs of rust or corrosion, if so, please clear if it has been checked above.

3. If there is still no troubleshooting, then it may be a problem with the battery, I don't know if your battery will heat up when charging, if the temperature does not change in the slightest, or it is the same as the temperature of the machine, it is considered that there is no normal charging, you can find customer service to replace, 4. You can also try some notebook BIOS has the option of battery correction, the specific method will be in the manual, if there is no option or can not find the manual, you can refer to the following practice.

Official Practice:1Put the battery in the notebook to drain the power.

Change the power options in the power control in the control panel, such as the time to turn off the display, the time to turn off the hard board, etc., to never, turn off the low battery warning, and then wait for the machine to automatically shut down when the power is low;

2.Reactivate the battery.

Three times in a row to completely discharge, shutdown and charge for more than ten hours, but try not to exceed twelve hours (depending on the battery instructions), the discharge can be discharged normally, not necessarily as thorough as the first time, but not while flushing;

3.In a certain period of time, try to fully charge and discharge the battery as many times as possible (the battery is not programmed, who said that charging and discharging three times can be fully activated?) How can it be so accurate) when using, try not to charge when the battery is still half charged or 30% (who said that laptop batteries have no memory effect), either use less for a while, 70% or 80% to charge, or use more 20% 10% and then charge.

Unofficial practice.

First use the mobile phone universal to rush to the top for half an hour, then clean it and recharge it to reactivate.

The probability that the computer cannot be charged is a hardware problem is relatively high, and it is recommended to go directly to the after-sales customer service to check it, and you can know the result, which is not very troublesome.

1. Cause analysis.

1) Software issues.

Generally speaking, many computer brands such as Dell, Lenovo, Sony, etc., will equip their laptops with power management software, if a certain "battery protection mode" is enabled, the power management software will disable the battery charging and discharging after detecting the user's use of AC power, so as to extend the battery life. So, if you find that your laptop is not charging, you can first go to the relevant power management software, turn off the battery protection mode or check the no charging option, and if there is no problem with the hardware, the battery will be able to charge.

2) The hardware itself is faulty, the battery itself is faulty, generally speaking, we can use to restart the computer, replug the battery to judge, if the battery still can't be charged, you may wish to install some hardware detection applications, get the approximate battery loss reference information. 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, it is recommended to take it for repair.

2. Security repair methods.

1) Enter the BIOS when the computer starts, usually find the "Start Battery Calibration" option in the power project, that is, "Start battery repair", generally speaking, the user will be reminded to connect the power adapter for full charging first, and then the text will be displayed to prompt the user to disconnect the AC power supply, the win7 system will continue to discharge the notebook until the power is completely exhausted, and then the notebook will automatically shut down, We can connect the power adapter to charge, but don't turn it on, and the whole process will be complete only after the charging indicator is off.

2) When the computer boots up, enter the BIOS, usually find the "Start Battery Calibration" option in the Power project, that is, "Start Battery Repair", generally speaking, the user will be reminded to connect the power adapter for full charging, and then the text will be displayed to prompt the user to disconnect the AC power supply, and the win7 system will continue to discharge the notebook until the power is completely exhausted, and then the notebook will automatically shut down, We can connect the power adapter to charge, but don't turn it on, and the whole process will be completed after the charging indicator is off.

The reason why the laptop cannot be charged may be:

1.Power adapter failure: The power adapter has many friends who call it a charger, although it is not accurate enough, but it is indeed very vivid. It's also very simple to determine if it's not due to the power supply, just replace it with a new power adapter.

2.Battery failure: The battery failure performance is relatively simple, most of the charging progress has been displayed at 100%, in fact, the battery life is less than a few minutes after removing the power adapter, or the battery cannot be detected directly.

Mainly due to the normal wear and tear of the battery itself, replacing it with a new one will do.

3.Motherboard failure: If it is useless to replace the power adapter and replace the battery, it is necessary to consider whether there is a problem with the motherboard of the computer, and then you need to send the computer to a professional repair shop to deal with the problem.

What to do if your laptop won't charge.

Hello is happy to answer for you, the possible reasons are as follows:1Power adapter failure:

If there is a problem with the charger itself, it may cause the charger to not be charged, but the computer can be used normally. You can try charging with another adapter, if it can be charged normally, it means that there is a problem with the adapter and needs to be replaced. 2.

Charger port Battery interface failure: If there are problems such as dirt or deformation in the charging port or battery interface of the computer, it may affect charging, it is recommended to clean these ports. 3.

Aging battery: If the charging effect of the computer is not obvious after a period of use, it may be that the battery has been used for too long and cannot be charged normally. It is recommended to replace the battery.

4.System software problem: If the above methods still fail to solve the problem, it may be a system software problem, and it is recommended to perform a system update or replace the operating system to fix it.
