If there is a problem with the battery charging, it is extremely inconvenient for people who need to work with their laptops outdoor. What should we do when laptop plugged in but not charging? Here are some reasons and solutions.
1.The adapter is broken and the laptop can't be charged
Whether the laptop not charged due to the power adapter is also very simple, the replacement method to test. This kind of fault is more common in DELL notebook.For example, DELL laptop adopts LBK (DELL architecture). The charging circuit design is quite special. If the adapter has problems, it will be plugged in not charging. And if it is not the original adapter, it will not be charged.
In HP's newer notebooks, there are some models that use this charging circuit. The classic failure is that the HP NX6400 CPU usage is 100% due to power error. For this reason, laptop charger won’t working, just replace the new original adapter to test.
2. Battery Damage
Battery failure performance is more obvious, the charging icon has been shown 100%. In fact, unplugging the power adapter it will continue to consume power quickly or can’t detect the battery. This is generally the life of the battery to the limit, we can judge this fault by calculating the battery life or the speed of battery consumption.
Tips: The notebook is always in a power-consuming state even when the notebook is turned off, to maintain the basic standby voltage on the motherboard. Once connected to an external power source, the battery will automatically start charging by default. To use the battery correctly, we recommend that the laptop be taken out of the battery for a long time, the battery power should be controlled at 40%, and stored at 15° Celsius or lower and charged once for about 1-2 months.
So, try another AC adapter and battery. Sometimes you can't find the same type of battery, you need to go to a professional laptop repair center for help.
The price difference between replacing the OEM battery and original battery is not very large, so the battery can generally be replaced directly.
The price of the original laptop battery is about one-tenth of the price of the laptop. The best choice is the original battery, which is safer in quality and life.
3.Laptop Not Charging Cause by Motherboard Problem
The notebook does not charge due to the failure of the motherboard is the most encountered in the repair of the notebook, because it needs to do chip-level maintenance.
There are two kinds of faults in the motherboard. From simple to difficult, the power port-circuit fault. This is relatively simple. The performance is that sometimes the battery is not powered down when the battery is not used, and the power is turned off when charging. There is also a connection between the battery and the motherboard that will cause anon-charging failure.
Then there is the circuit failure. Generally, the charging circuit and the protection isolation circuit are malfunctioning. Such as the common charging IC MAX1772, ADP3860 (the charging chip commonly used in the IBM model).
In addition to the chip itself is easily damaged, the damage of its peripheral circuits is also very common.There is also the EC itself and peripheral circuit faults, EC is the upper circuit of the charging IC, responsible for turning the charging circuit on and off.
Note: The detection of the causes of laptop not charging are more than the above. If your notebook also has this fault, you can read this article in detail.
BIOS (Basic Input/Output System) is the program that manages the connection between the operating system and the laptop hardware devices. Sometimes faulty BIOS settings can result in the laptop not charging issue. You can update your BIOS to fix the faulty settings.
This type of motherboard failure can be attempted to update the battery by firmware before being sent to the repair professional. Some notebook manufacturers embed battery correction programs in the BIOS firmware (such as ASUS), we can test whether the battery charging failure can be solved by updating the BIOS or restoring the BIOS default program.
4.Forced Hardware Reset for Laptop Saying Plugged in not Charging
4.1 If your laptop has an external battery, remove the battery and all external power adapter, press the power button for more than 15 seconds, then connect the battery and power to boot and charging.
4.2 If it is a built-in battery model,you need to remove the power adapter. Generally, there will be a small hole on the back of the notebook, called the "reset hole". You need to press the reset hole with a needle, then connect the power to the boot test to see if battery can be charged.
5. Laptop Plugged in not Charging Windows 10 Update
If your laptop can't charge to the battery, even if it is plugged in,
this is what you need to do:
5.1 Open "Device Manager" by searching for Device Manager or by right-clicking the Start button and selecting.
5.2 Click on the battery on the list to expand it and you should see two items: Microsoft AC Adapter and Microsoft ACPI Compatible Control Method Battery.
5.3 Right-click each item and select "Uninstall Device". Yes, you are uninstalling the laptop's battery driver, but don't worry, because it will automatically reinstall when you restart your laptop.
And the update is performed on the Windows update interface. In the networked state, the system will automatically download and install the adapted driver, and then restart after completion.
6. The Laptop Says 0% Available Plugged in Charging
6.1 Check whether the laptop settings disable battery, and some laptop battery management software or bios also has a disable charging function, you can check it.
6.2 If your laptop battery is hot to the touch, excess heat may interfere with the charging process. Turn off the computer and let it sit for a few minutes to cool. If you have not cleaned the vents of your notebook recently, blow a can of compressed air at a certain angle (for a short time) into the fan vents to remove some dust. It may also be because the battery has been left unused for too long, resulting in poor contact. It is recommended to open the laptop to clean the dust, plug the power adapter and the battery, and use the professional cleaning tool to clean it in the interface. It may also be solved.
6.3 If there is no problem with the inspection settings, then most of the battery internal control cables or batteries have problems and need to be repaired.
6.4 When some laptop batteries have been used for a long time, over-discharge,resulting in the 0% available power has been connected to the uncharged. It is best to buy a new laptop battery to replaced.
7. When Battery is Charging Stuck at a Number and Cannot be Charged to 100%
This may be due to some settings in the power management software. For example, the ThinkPad's power management software has the option to set the battery charging threshold. This option can better maintain the battery life. So, if you have other battery management software, when there is a battery not charging laptop, you should check the power management software first, or uninstall him to test if the problem is solved.
8.Reset Windows System
If your battery is new and none of the above solutions solve your problem, you will need to try resetting the Windows 10 system. Because this operation requires you to backup all your data, and it will have a big impact, so it is recommended only if all the above methods are invalid.
If reinstalling the operating system still does not solve the laptop battery charging error, then refer to the possibility in the above the 3 way, you need to send the computer to the repair store to repair the motherboard or the circuit.
The Bottom Line:
The computer indicates that the power has been plugged in, but the battery has not changed. Most of the failures are caused by the battery life. You may need to purchase a new battery for your laptop. Before purchasing, please try whether you can solve the laptop not charging even with new battery according to the above method.
