What should I do if my laptop battery won't be charged? The reason why laptops are so popular is that they are equipped with batteries that are capable of using it for five or six hours without power. Once the battery runs out, it needs to be recharged.

However, some users reported that their batteries could not be charged, what is going on? Today, U Daxia will talk to you about the reasons and solutions for the laptop battery not charging.

Laptop.

Cause analysis: 1. Software problems.

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. There is a problem with the hardware itself.

Generally speaking, we can use restarting the computer and replugging the battery to judge, if the battery still can't be charged, you might as well install some hardware detection applications 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, it is recommended to take it for repair.

Have you tried changing the adapter?

1. Use a multimeter to check whether the socket is normal and whether the power supply voltage is 220VIf the mains voltage is abnormal, it is recommended to replace the use environment test.

2. Use a multimeter to check whether the output voltage and current of the power adapter are consistent with the marked. If the gap is very large, or there is no output voltage, and the mains voltage is normal, it can be judged that the power adapter is faulty and the laptop power adapter needs to be replaced.

3. If the above check is normal, Changpai removes the laptop battery and does not connect an external adapter. Press and hold the power on/off button for 5 seconds and repeat 3 times. After releasing the residual charge of the notebook, plug in the power adapter separately and power on for testing.

4. If the fault persists, check the power interface of the notebook to see if it is abnormal.

5. The above checks are normal, and basically it can be preliminarily judged to be a failure of the notebook motherboard.
