The use of notebooks is now a very common phenomenon. When the number and frequency of use remains high, some minor problems will inevitably occur. Failures include failure to charge. Faced with this phenomenon, many people don’t know where the problem lies, let alone how to fix it. If they ask professionals to repair it, they will not be able to use it normally for some time. If they can master some knowledge in this area, they can The difficulty can be eliminated. The editor below will introduce to you laptop computer battery not charging .
1. Circuit failure of laptop battery not charging
< p style="text-indent: 2em; text-align: left;">When you find that the computer cannot be charged, you should check whether the charging circuit and the protective isolation circuit are faulty. In addition to the chip itself being easily damaged, damage to the circuits around it is also common. Like extremely small zener diodes, this kind of failure is quite time-consuming in early repair work. There are also faults in the EC itself and its surrounding circuits. The EC is the upper-level circuit of the charging IC. If it fails, it will also lead to failure to charge.2. The laptop battery cannot be charged due to power adapter failure
First of all, you can determine whether it is not charging due to the power supply. Just use the substitution method. Take DELL notebooks as an example: Since DELL notebooks use LBK, the charging circuit design is quite special. If there is a problem with the adapter, it will not charge. Exceptionally, if it is not an original adapter, it will also not charge.
3. Laptop battery charging Battery failure that does not receive power
If it is a battery failure, you will find that the charging progress is always displayed, but when the power is removed The adapter will not detect the battery within a few minutes. This is mainly due to the normal wear and tear of the battery itself. The battery, optical drive, and fan consume a lot of power when in use.
4. Laptop battery failure due to motherboard failure
There will be two situations when the motherboard fails. One of them is: a non-charging failure caused by the virtual soldering of the interface between the battery and the motherboard. The other is a power port-circuit failure. The symptoms of a power port failure are: When the battery is not in use, it sometimes loses power and is recharged. You can make a judgment by using the manual power port.
The above is the relevant content about the laptop battery not charging, I hope it can help everyone Helpful!
