What happens if your laptop doesn t charge for too long?

Not charging a laptop battery for a short time (a few days) after it runs out has little effect on the battery; If the laptop is stored for a long time and not recharged, it will cause the battery to gradually fail or the capacity will decrease. After the battery is automatically shut down after it runs out, it generally cannot be turned on normally, and the power adapter needs to be plugged in.

You can. One of the most widely circulated sayings about the use of laptop batteries is "be sure to use automatic shutdown and recharge", and to put it professionally, it is to perform deep discharge every time. This statement is in nickel-metal hydride batteries.

Times, because of the existence of the memory effect, makes sense. But we are in the era of lithium batteries, and it is best not to do this deliberately, because long-term over-discharge may damage the electrolyte of lithium batteries.

performance, resulting in unsmooth charging in the future, and serious will reduce battery life. Of course, don't dare to use the battery when you need it, over-discharge protection will not be idle, and the meaning of its existence is not to let your battery be seriously damaged.

All in all, the advice on when to start charging is to charge when it's convenient to charge.

Remember that when you buy a computer, the shopping guide will tell you to charge the first 3 times for 12-24 hours. In fact, because of the existence of battery charging chips, there will no longer be charging current after being fully charged, charging for so long is not only meaningless for the battery, but most importantly, it delays our time to play with the new computer!

The conclusion is that you can pull it out if it is full, and you can pull it out if it is not full, which will not affect the life of the battery. You don't have to wait 12 hours at all.

Myth 3: If it is fully charged, you can't continue to plug in the power supply.

Many people think that charging after 100% full charge is "overcharging", and it feels like it will be ** in minutes. In fact, the real problem with the use of 100% fully charged plug-in cables is "storage passivation", which is especially serious when fully charged. It doesn't matter if you don't understand the principle, the following conclusions can be optimistic:

The battery will be charged and discharged at least once a week, and there is basically no need to worry about this problem;

Perennial plug-in and full power use will indeed produce passivation, and at the same time, high temperature will greatly accelerate the passivation and aging process;

Batteries are often used, and the passivation is not too obvious if the power is not unplugged after the occasional full charge. However, do not use it on quilts, pillows, or other things that block the heat dissipation holes, and do not use it in places with high temperatures all year round.

Storing a laptop for a long time without charging it will lead to the gradual failure of the battery or a decrease in capacity. After the battery runs out and automatically shuts down, it generally cannot complete the normal boot, and you need to plug in the power adapter before you can do it.

Generally speaking, a complete charge and discharge should be done once a month, that is, the battery should be fully charged at one time after all the batteries are exhausted. This can greatly improve the battery life.

There are three main types of batteries used in laptops: nickel-cadmium batteries, nickel-metal hydride batteries, and lithium batteries; They are generally expressed as: nickel-cadmium Ni-CD, nickel-metal hydride Ni-MH, lithium battery Li.

Laptop batteries are lithium-ion batteries that consist of a shell, circuit board, and cells. Generally speaking, the battery cell refers to the number of cells in the battery, and the mAh refers to the capacity of the laptop battery. Battery cells are like small batteries, and the small units with voltage are combined in series, which is the battery we see.

For example, if a laptop battery is, and then divide it to get 4, it proves that 4 batteries are connected in series. Then look at the capacity of the whole battery, for example, 4400mAh, it proves that there are two sets of battery packs in series mentioned above, because those small batteries have a capacity of 2000-2200mAh, or even more, and the two groups must be combined together to reach 4400mAh. According to these two judgments, this battery is 4 2 = 8 cells.

The circuit board is mainly composed of two parts: a protection circuit (or a secondary protection circuit) and a capacity indication circuit, which manages the charge, discharge and safety of the notebook battery.

The standby time of a laptop battery is mainly determined by the mAh value. In general, the higher the number of cells, the greater the mAh value and the longer the standby time. The life of a notebook battery is mainly measured by the number of charging and discharging, and the quality of qualified products is generally 500-600 times.

Therefore, the effective life of laptop batteries is less than 2 years, and expired batteries will age, and the standby time will drop sharply, which will affect the mobility of laptops.

If your laptop has not been charged for a long time, you need to install the battery on your laptop to charge it, or replace it with a new battery.

First, the results caused by the laptop not charging for a long time:

1. The battery still has a very low or partial power, and the laptop can be used normally after charging.

2. The battery of the laptop is exhausted, it can't be charged, and the laptop can't be turned on.

Second, the solution:

Install the battery in the battery slot of the laptop to charge, if the battery is completely depleted, you need to wait for a while for the battery to charge normally. If the battery still can't be charged normally after charging for a period of time, and the laptop can't be turned on, you need to take it to the aftermarket to replace the new battery.

Third, the daily maintenance of the notebook:

1. Don't unplug the laptop battery and put it to sleep, try to charge it from time to time, and it is best to discharge and charge the electric oil once a month.

2. The notebook should be used frequently to prevent the internal wiring from being damp, and it should be turned on frequently.

3. If the battery has to be unplugged and stored, it is recommended to seal it in a packaging bag and store it in a dry and cool environment.

4. Try not to remove the battery, now there is a monitoring circuit inside the laptop battery, and it will automatically stop charging when the battery is fully charged, so it doesn't make much sense to remove the battery and save it.

Fourth, the reason for the automatic discharge of the laptop battery:

1. Since the inside of the battery cell of a laptop battery relies on chemicals and metal ions to store electricity, the stability of chemical substances will be affected by time and temperature. Even when stored in a conventional environment, the activity of the chemicals within the cell will collapse over time, and the battery's ability to store electrical energy will deteriorate.

2. Even if the laptop battery is not in use, its battery protection board is still working, in other words, it has been consuming battery power.

Generally speaking, if the laptop is not charged for too long, it may be in urgent need of charging as soon as it is turned on, you don't care whether you have charged it before or not, and when you want to enable it, it is best to charge it first.

In the process of using the laptop, if it is not charged for too long, it will lead to insufficient power, and it will also affect the effectiveness and safety of the laptop.

Then your battery will starve to death, once the battery starves to death, it can no longer be charged, you have to replace the battery with a new one, it is recommended not to let the battery in a state of not charging for a long time, it is very necessary to keep the notebook in a state of power often, of course, the local tyrant is at will.

It has a great impact on the battery, which can easily lead to over-discharge of the battery and cannot be charged.

If you don't use the laptop for a long time, it is easy to cause moisture inside, which can then corrode the circuit board and cause damage, so you should take it out every few months and charge it once every few months and turn it on for two hours to heat the laptop to exhaust water vapor.

1. First of all, check whether the battery charging is disabled in the laptop battery settings, and some laptop battery management software also has the function of disabling charging, you can check it; 2. It may also be because the battery has been put for too long and has not been used, resulting in poor contact, it is recommended to open the laptop to clean the dust, unplug the power cord and battery, and it may also be solved. 3. If there is no problem with the check settings, then most of the problems with the internal control circuit or battery cell of the laptop system need to be repaired. 4. When some laptop batteries have been used for a long time and are over-discharged, resulting in 0% of the available power supply has been turned on and not charged, and it will be repaired later, even if it is repaired, the battery life and life will not be long, it is best to buy a new laptop battery to replace it.

The battery will automatically age, which will cause the battery to not be charged, so it is recommended to use it for a long time.

Let's start by troubleshooting software issues. 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. Therefore, if you find that the laptop is not charging, you can first enter the relevant power management software, turn off the battery protection mode or check the prohibition charging option, and if there is no problem with the hardware, the battery will be able to charge.

It could be a hardware failure of the battery itself. If the battery still won't charge, you might as well install some hardware detection apps to get an approximate reference information about battery drain. 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**.

Here is a more effective battery repair method. Entering the BIOS when the laptop boots, it is common to find the "Start Battery Calibration" option in the Power project, which is "Start Battery Repair". Typically, this will first prompt the user to connect the power adapter for a full charge, then display a text prompting the user to disconnect the AC power supply, and the laptop will continue to discharge until the battery is completely depleted.

After that, the laptop will automatically turn off, and you can connect the power adapter to charge, but don't turn it on, and the whole process will be completed only after the charging indicator is off. The BIOS battery repair process can take up to 5 hours, so be sure to do it when you don't need to use your laptop. If this does not improve the condition of the battery, it will be necessary to repair it or purchase a new original battery.

The last problem that can cause the laptop to not charge is a faulty power adapter, but it is very rare, and there is no suitable self-test method, so it can only be sent to a repair station for testing.

Buy something big and charge for a longer time. It really doesn't work, you can use the power adapter directly, there is no effect, and there is electricity in the general working place.

If you have to use the battery, you have to replace it with a new one.

Then you have to change the battery.

Summary. It is better to keep the laptop plugged in, after the laptop battery is fully charged, the power supply will directly power the laptop, and there is no need to go through the battery conversion, so it is better for the laptop to be plugged in and used all the time, which not only saves the life of the battery, but also makes the power supply more stable and will not cause harm to the computer's battery.

Is it better to charge the laptop all the time or not when you use it.

It is better to keep the laptop plugged in, after the laptop battery is fully charged, the power supply will directly power the laptop, and there is no need to go through the battery conversion, so it is better for the laptop to be plugged in and used all the time, which not only saves the life of the battery, but also makes the power supply more stable and will not cause harm to the computer's battery.

Can you add, I don't quite understand it.

However, it is important to note that if the battery is not used for a long time, it may cause the battery to passivate, so it is recommended to use the battery power occasionally.

I believe that most of the friends who use laptops may encounter the above problems, so there are many reasons why the battery cannot be charged, not necessarily caused by the laptop not being used for a long time, in the previous many issues of Q&A, I have talked about the general idea of repairing the computer is "soft first and then hard", in this issue is no exception, and then I will explain in detail and demonstrate the method to solve this kind of failure,

First of all, the first method: open the notebook and use it until all the battery power is used up, and then try to charge it, and the detailed operation steps are shown in the figure below

The second method: remove the laptop battery and reinstall it, the detailed operation steps are shown in the figure below

The third method: (1) Click "Start" - "Settings" - "Control Panel" - "Change Plan Settings" in turn, and then click "Change Advanced Power Settings", the detailed operation steps are shown in the following figure

2) Enter the "Advanced Settings" option to check whether the battery is set to "Disable Charging", the detailed operation steps are shown in the figure below

The fourth method: boot and hold the "Delete" button to enter the BIOS interface, select "StartBatteryCalibration" (battery repair), and knock enter, as shown in the following figure

The fifth method: most of the factors that the laptop cannot be charged are caused by the "battery", if you confirm that there is no problem with the "battery", then it is likely to be the fault of the "power adapter".

It is very likely that the battery has been on standby for too long, resulting in the internal damage of the battery, so you can only replace the new battery.

1. The power adapter is faulty.

When the laptop's power adapter fails, the computer will not charge properly.

2. Battery failure.

When the laptop battery is aging or leaking, the computer will naturally not be able to charge normally.

3. The motherboard is faulty.

When the motherboard of a laptop fails, it will lose power faster when the computer is not in use, and charging will be intermittent.
