Why does the Acer laptop suddenly fail to charge?

Regarding the above questions, first of all, check whether the original charger is correct.

Often. Check whether there is poor contact inside the original charging data cable.

Elephant. Check whether there is poor internal contact between the charging data cable plug and the charging interface of the notebook.

Condition. Check whether the battery inside the notebook is normal (this inspection is best to ask a professional master to test the internal battery of the notebook).

After the above checks, if everything is normal, then this situation may be a problem with the charging control circuit on the motherboard.

1.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 prohibit battery charging and discharging after detecting the user's use of AC power, so as to extend the battery.

2.Security Fix Approach When entering the BIOS when the computer boots up, it is common to find the "Start Battery Calibration" option in the Power project, which is "Start Battery Repair", and generally speaking, the user will be reminded to connect the power adapter for a full charge first, and then it will.

Why does the Acer notebook suddenly not charge, it is possible that the battery has reached its service life, because the general lithium battery only has a life of about 500 charging times, and more than this number of times is considered to be earned.

There are three main reasons why laptops are not charging:

1. Generally speaking, many computer brands such as Dell, Lenovo, Sony, etc., will equip their laptops with power management software. If a "battery protection mode" is enabled, the power management software will prolong battery life by disabling charging and discharging the battery when it detects the user's use of AC power.

2. It is also possible that the battery itself is a hardware failure. Generally speaking, we can use restarting the computer and replugging the battery to tell if the battery still won't charge, you might as well 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, and do not blindly believe some so-called tips on the Internet, which may lead to the battery**even**.

3. The last problem that may cause the laptop to fail to charge is the power adapter failure, but it is very rare and can only be sent to the repair station for testing.

Solution: Detect the power adapter, battery itself, battery management IC chip and other hardware devices, if the fault cannot be determined, it can only be sent to the repair center for processing.

First check if you have the battery software installed, and if so, switch the charging mode of the battery.

If not, it may be due to the following reasons:

1. The battery is protected.

2. There is an error in the BIOS recording.

3. The battery interface is slightly loose.

4. The voltage of the power adapter is low.

For the above reasons, you can try the following solutions:

1. Activate the battery: turn off the battery and charge the battery for half a day or about a day.

2. Update the BIOS and reboot the system.

3. Plug and unplug the battery

1) Turn it off, unplug it, and unplug the battery.

2) Plug it in and turn it on.

3) Turn off and unplug the power.

4) Plug in the battery and plug it in. At this time, the battery indicator light is on, which means that it can be charged normally.

5) Power on. The message "Power is on, charging" is displayed.

4. Replace a power adapter with the same specifications.

1. Cause analysis:

1. The battery is damaged. 2. System failure. 3. Charger reasons or poor contact.

Second, the solution:

1. Try to change to another charger or data cable, or clean the charging port.

2. Boot into recover mode, select advancsd advanced mode, select wipe battery, and clear battery traces.

3. Restore the factory settings to see if it is the system reason.

4. If the battery is damaged, it can only be sent for repair and replacement.

The reasons why the laptop cannot be charged are as follows: First, check whether the rechargeable battery of the laptop is normal Second, check whether the rechargeable battery contact part of the laptop is in good contact? Finally, it is possible that there is an abnormality in the charging circuit of the notebook.

If the battery is broken, or there is a problem with the charger, it is recommended to replace it.

Hello, I am Xiao Ai, an electronic consultant, and I am happy to answer for you Please later, I am working hard to sort out the answer for you, and I will reply to you soon

Dear, this is a battery hardware problem, that is to say, the battery is aging. If it is within the warranty period, you can get the corresponding warranty point for warranty, so you can do it without charge. May you have a light when it's dark, an umbrella when it's raining, someone to accompany you on the road, and if there are no other problems, I wish you a happy life.

Questions. What is the situation of you, I want to disassemble the battery, pay to ask how to disassemble, I don't explain it, what should I do?

One of the masters asked me to open the lid the way he said, and there were no batteries found inside.

Dear, notebooks need to be specially repaired and after-sales to do, and hardware problems cannot be solved online.

This is just to give you the best advice.

If the laptop battery is broken, it can only be replaced, and there is no other way to do this.
