What To Do If The Laptop Battery Is Not Charging? Software, Firmware And Methods Of Replacing Batteries, Etc.

Many friends have encountered this situation: the notebook is connected to the power supply, but the battery icon in the lower right corner shows "not charging".

It's obviously connected to the power, but the battery is not moving, and is even dropping.

Don't rush to replace the battery at this time, let alone send the computer for repair directly.

In fact, a large number of problems are not charging problems and can be solved with the help of a simple software method. Today I will talk to you about the detailed operations and precautions when using the battery in daily life.

Try software calibration first

Many notebook brands come with their own battery management software , can be used to calibrate the battery.

This notebook from Lenovo and IBM is used as an example, and a program called "Battery MaxiMiser and Power Management" is pre-installed in the system.

After running it, select the battery maintenance or calibration function, and the software will automatically control the computer to charge and discharge.

First, the computer will be fully charged during the entire process, then it will slowly drop to a very low battery state, and finally it will be fully charged again.

This process is to recalculate the true capacity of the battery and correct the system's judgment errors.

There are many "not charging" situations, and there are also situations where "the battery runs out of power after a short period of use". In this way, it can be restored to normal state after one operation.

Refresh in BIOS

If you can't find the management software above on your computer, don't be discouraged.

There are also many manufacturers Battery calibration function Directly integrated into BIOS inside.

For example, on some models such as ASUS and Dell, when the logo interface is just displayed when the machine is turned on, press F2 (or Del or F10, depending on the prompts given when turning on the machine), so that you can enter the blue and white BIOS setting interface.

Find an option like "Battery Calibration", select it and press the Enter key. The screen will turn black and the computer will start automatically calibrating the battery.

This process takes a relatively long time, about four or five hours. During this period, you can neither power off nor operate the computer. You just need to wait for it to end on its own and shut down.

Finally consider replacing the battery cells

If you have tried the above two software methods and the battery still cannot be charged, and the battery has been used for more than two or three years, it is very likely that the battery core has naturally aged.

At this moment, some friends will come up with the idea of ​​going to a repair shop to "replace the battery core." The so-called "replacement of the battery core" is to disassemble the battery case and replace the lithium battery inside with a brand new one.

But to be honest, this method is very risky.

If you do it yourself, it is very easy to damage the protection circuit inside the battery, and there is even a risk of short circuit and fire.

Even if you go to a small shop on the roadside for replacement, the quality of the welding involved and the source of the battery cells are difficult to guarantee. After the replacement is completed, the battery may not be used normally, or the computer may not recognize it at all.

Nowadays, most laptops have built-in batteries, which are compact in structure. The safest way is to directly purchase a new officially certified battery to replace it, which is worry-free and safe.

Avoid two pitfalls for daily use

The problem of not charging has been solved. How can I make the battery last longer with daily use?

There are two "old experiences" that we often hear are actually wrong.

The first misunderstanding is " Every time it needs to be refilled with light ".

Today's notebooks are all equipped with lithium batteries, and there is no memory effect. However, once they are over-discharged, that is, when automatic shutdown is used, it will cause extremely serious damage to the battery.

A better habit is to plug in the power when the battery reaches about 20%. There is no problem in unplugging it after charging to more than 90%.

The second misunderstanding is " You can put it on the bed as long as the power is turned off and the power is off ".

After shutting down, there is still a weak current inside the computer. If it is placed in a soft and airtight place such as a quilt or pillow, the heat cannot be dissipated. Although the probability of this happening is very low, there have been reports of the battery overheating, bulging, or even catching fire.

For safety, it is usually best to place your laptop on a desktop or hard tray.

Pay attention to storage and temperature

There is such a situation that some friends will encounter situations where they need not to use the computer for a long time, and how to save the battery is also a sophisticated knowledge.

Neither Fully charged to save , let alone Completely photoelectrically preserved .

When the battery is fully charged, it will cause the battery to be in a high-voltage state for a relatively long period of time, thereby accelerating aging; if the battery is completely discharged, it may cause the battery core to "starve to death" due to low voltage, so that it can no longer be charged.

The relatively scientific behavior is to use the battery power to about 40 to 50%, then turn off the power and place it in a cool and dry place.

in addition, High temperature is the number one killer of lithium batteries .

If the indoor temperature is quite high in summer, and you often use the computer with the power plugged in in a fixed place, then if the model is an old and removable model, you can consider removing the battery, or setting the charging threshold to prevent the battery from being fully charged and at high temperatures.

In fact, software calibration and correct usage habits can make most batteries last three or four years and still be in good condition.

When encountering a situation where it cannot be charged, first start with the simplest software and BIOS calibration that comes with it. Many times it is just a fault that does not really exist.
