How to Avoid Laptop Battery Swelling

Laptop battery swelling may be caused by the battery being used in an overheated environment or the battery is too old. The laptop battery uses lithium batteries. What causes the laptop battery to be swollen and how to fix swollen laptop battery?


Laptop Battery Swollen Reason

1. Generally speaking, a small amount of gas is generated inside the battery during charging and discharging of the commonly used lithium ion polymer battery, which is generally absorbed during discharge, so it is normal for the laptop battery slight swelling.

2. If the appearance of the battery is obviously bulging, it is likely that there is a problem with the battery itself. For example, the voltage and current are too large, and the battery will be overheated and deformed.

3. There is no protective plate inside the laptop battery, the distribution of positive and negative is error.

4. Other reasons may cause problems with the battery, such as the battery impurities inside, or electrolyte leakage.

5. The battery has been used for along time, and the swelling battery should be discarded, and continued use it will cause safety risks. Once it is determined that the battery is swollen and malfunctioning, you must stop using it and seek a replacement battery.

How to Avoid Laptop Battery Swelling?

1. After the battery is fully charged,please unplug the power adapter and replug it after draining battery.

2. This is especially important when using the device for the first time. when you get a new battery, please insert adapter before the battery is completely discharged. Wait for the device to turn off before you start charging the battery.

3. If you want to leave the laptop idle for a long time, please remember to remove the battery and store it separately.

4. It is forbidden to use the laptop on any fabric surface, this will make the battery fan not work properly and cause the battery to overheat quickly.

5. Try to keep the battery cool. If you want to work on the laptop for several hours, for example, it is best to lift the back of it with a book to allow better air circulation.


6. Please use a best charger. If you don't have the original charger for the battery, please get a charger with exactly the same output power as the original charger. Just choose the charging plug is suitable does not mean it is suitable for your laptop battery configuration.

7. The laptop C D cover is opened for no reason. At this time, you should pay attention. Usually in the case of battery expansion and in this case, it is usually impossible to close the back cover.

Why My Laptop Battery Does Not Fully Charge

How to Fix Laptop Adapter Making Beeping Sound

I have a Dell Inspiron 6400 and have used it for many years. Now when I use it, why does my laptop adapter produce electric buzzing sound? Is something wrong with it?
In this post, I will tell you how to solve laptop charger making noise yourself.


It is normal for the computer adapter to make electrical noise. Because the power adapter will emit a sound with a fixed frequency when switching the power supply, because the rated power of the inductance coils of different frequencies is different, the sound of the induced current is also different.

There may be many reasons why the laptop charger making beeping noise and cannot charge the laptop correctly. Here are some possible reasons and solutions.

1. The Cord of the AC Adapter is Loose

The laptop needs to be charged with DC power, so the AC adapter will convert the AC voltage to DC voltage, but if the AC power cord is loose for some reason and the AC adapter cannot supply power normally, it will beep.

Check whether the power jack of the adapter is correctly inserted into the laptop plug. The correct jack should beeasy to plug into the laptop. Make sure that the AC power cord is properly connected and the AC adapter is working properly.

2. Check the Appearance of the Charger

Check the power cord for signs of burns, frayed wiring, and severe kinks. Any of these symptoms indicate that the adapter cord is malfunctioning and the cord needs to be replaced as soon as possible.


3. Is the Charger Overheating?

If it is, the normal working environment will not generate too much heat. Please remove the items that affect the heat dissipation of the charger and make sure that the laptop charger is working at a suitable temperature.


4. Is the wall socket supplying powernormally?

Another reason that may be a faulty power outlet. Therefore, your AC adapter cannot supply power normally and will beep.

Please make sure your AC adapter is properly connected to the socket, or try to replace the socket.

5. Laptop Adapter Short Circuit

The main reason for the beeping soundof the laptop charger is a short circuit in the DC circuit. The solution is checking the short circuit with a multimeter, and then solder it correctly, and make sure that DC "+" and DC "– " do not touch each other.

The adapter may cause a short circuit because it provides too much power. Check the voltage output of the adapter with a voltmeter and compare the reading with the value listed on the adapter. Small fluctuations above or below the listed value are normal, but if the reading changes too much, it indicates that the power cord is faulty and needs to be replaced.

If using another replacement adapter does not any noise, you need to replace the laptop charger.

If laptop charger making noise and not charging even with other adapters, and the computer need to check and repair.

6. Replace the Adapter that Beeps and Does not Working

In most cases, Dell can provide a replacement power supply compatible with your laptop model.

A laptop power supply failure should normally be covered by the Dell's warranty, unless the power supply is damaged by water or abuse. If Dell no longer has the replacement adapter or is not covered by the warranty, you can purchase a universal power adapter from most laptop repair stores. This will save you more cost than buying the laptop adapter from the brand website.


Replace the faulty power supply as soon as possible, as it may surge and damage the internal components of the laptop.


The above is about why is my laptop charger making noise and solutions. If it still cannot be repaired, I suggest you buy a new laptop charger. You can buy a new and original charger from GEMWON.

How to Fix Screen Backlight Not Working on MacBook

One day my screen started flickering then it went black. I thought the LCD/LED screen was dead but on further investigation (shining a light through the apple logo) I found that the screen is working fine it’s the backlight. Why is my backlight not working mac laptop? How to fix MacBook display backlight not working?


Why is my Backlight Not Working Mac Laptop?

No matter which MacBook you are using, if you do not touch the keyboard or mouse, the power settings may dim the screen after a few minutes. This is a warning that the display will go to sleep soon, so adjust the sleep settings to eliminate this problem.

How to Adjust Power Settings MacBook?

1. Click the "System Preferences" icon in your Mac's dock, or click the "Apple" menu and choose "System Preferences."

2. Choose the "Energy Saver" icon from the "Hardware" area.

3. Choose "Battery"from the top of the window.

4. Click and hold on the slider next to "Display sleep" and drag it to the right to increase the amount of time before the display goes to sleep. You can set it anywhere from 1 minute to 3 hours or "Never."

5. Deselect the box that says "Slightly dim the display when using this power source."

6. Deselect the box that says "Automatically reduce brightness before the display goes to sleep" if you do not want dimming as an indicator that your display will sleep soon.

7. Select "Power Adapter" at the top of the window and use the same method to adjust your sleep settings. The "Slightly dim the display" option does not appear in this pane, as it is designed to help prolong battery life and is therefore not relevant when your computer is connected to the power adapter.

8. Click the red "X" in the upper left corner of the window to close the power saver settings when you are finished.


How to Set the MacBook Pro/Air Screen from Dimming with Ambient Light

Please open the "System Preferences" window from the Apple menu and select "Displays".Enable "Automatically adjust brightness" and your Mac will use the ambient light sensor to automatically adjust the brightness. Disable this option and your MacBook will not perform this operation.

Check Screen Hardware

To check the display, connect the system to an external monitor to see if you can see the desktop icon on the external monitor. Then take a flashlight and place it on the desktop at an angle to see if you can see the blurred outline of your desktop icons.

If your external monitor is working properly, and the light of the flashlight allows you to see desktop icons, the problem can be attributed to a malfunction of the backlight circuit.


Okay, that's the problem. There is a chip on the logic board that converts the power from the battery (DC) to the correct voltage for the backlight LED. These are usually damaged by getting the system wet, if you have ever put the laptop on a wet surface or somethings plashed on it.

If you don't have Spilled Water on a MacBook?

A completely extinguished screen usually points to a blown fuse, and the ribbon connection inside the cover maybe damaged. Usually, I regard the recessed cover as the root cause. Has the computer been hit?

Therefore, if you open the bottom cover, you can see whether the inverter chip is damaged, and it is usually obviously burned. This is the logic board. The blue chip is what you want to view: the logic board. The display ribbon cable is connected at an angle to the logic board on the left side of the yellow marked chip.

Conversely, if the image displayed on your external monitor is also display colored lines, it means that there is a problem with internal hardware such as the motherboard or graphics card, and you need more hardware detection.


Update Graphics Card Driver

The horizontal or vertical lines on the MacBook screen are related to the software, and the most likely culprit is your outdated graphics card driver. You should upgrade it to the latest version to resolve driver compatibility issues. For this, you can go to the driver download page of the computer manufacturer to obtain the appropriate graphics card driver.

How to Fix MacBook Some Keys not Working

When turning my MacBook back on I noticed my J key does not work. Do I need to replace the entire keyboard or is there something else I can try? What should I do if my MacBook keyboard not working?


1. Set Option to Turn off the Mouse Keys

Most of the keys on the keyboard can respond, but nothing is entered when u, i, o, j,k, l is typed.

From the replies in the forum, many people have mentioned this problem. Just cancel the setting.

The method is as follows:

System Preferences - Accessibility - Mouse and Trackpad - Options -"Press the option key five times to toggle Mouse Keys"


If the account you logged in has disabled the mouse button, but the MacBook keyboard does not respond, switch the button of the mouse button to "On" and"Off" to restore functions.

Double-clicking option 5 times is used to turn on the keyboard to control the mouse pointer, so the mouse button is the most obvious indication that the MacBook air number keys not working. When you type numbers, the mouse cursor moves very slightly.Therefore, if you try to type a number, the mouse cursor on the screen seems to be shaking in a small area.

2. Software Conflict

MacBook keyboard stops working after login. So, it may be that the keyboard is not broken. After entering the system, due to some program conflicts, the keys do not respond.

Does it happen after installing a new application? It is very common for applications to cause conflicts and cause other error. Try to delete the latest application to check if the MacBook keyboard is working.

MacBook some keys stopped working maybe caused by the driver not being loaded or the keyboard setting error. The most straightforward solution to this is to reinstall the system. If there installation MacOS is too troublesome, you can try to check background services/programs, check the programs and services whether it is normal uninstall. Troubleshooting is a waste of time and some service cannot be checked.


When resolving software conflicts. Prioritize virtual OS, optimization application,etc. Due to the operating system environment, such problems may be caused.

3. Perform PRAM Reset

5. MacBook Some Keys not Working after Spill

Many users have reported repeated or unusable keys.
