Are you been using a laptop for several years? It is good when the laptop is running smoothly for a long time without any issues. However, you cannot take that for granted as the CMOS battery will stop working eventually. So, you need to know how to remove the CMOS battery from the laptop. CMOS is a vital part of your laptop that is in the charge of storing all information about vital settings.
If you are wondering if the CMOS battery is removable or not, then the answer is yes. You can remove and replace it if you have the right tools and you know the steps. However, if you are not sure about the steps, you will need to learn them first. So, let’s take a look at the steps without any further ado.
What Is The CMOS Chip?
Before learning the steps to remove it, you need to know what a CMOS chip is. The full form of CMOS is “Complementary Metal Oxide Semiconductor.” It is one of the most important parts of a laptop that helps power the laptop’s BIOS firmware. BIOS needs to be fully operational even when the laptop is not plugged. This is when the CMOS battery comes in handy.
BIOS runs using the CMOS battery to stay operational when you turn off your laptop and unplug from a power source. Not only laptops but the CMOS batteries are also used on desktops. However, the use of CMOS batteries is much more frequent in laptops. The average timespan of CMOS batteries is around 3-5 years.
Reasons To Remove The CMOS Batteries?
There are plenty of reasons available for removing the CMOS batteries. One of the most common reasons is when your laptop starts to lose time and date settings very often. This happens when the CMOS battery malfunctions and fails to meet the power demands.
Apart from that, you might also get an error message that will warn you about the damaged battery. This message mostly appears during the boot-up process of the laptop as “CMOS Read Error” or “System Battery Voltage Is Low” If any of these messages are showing on your laptop, you will need to replace the CMOS battery as soon as possible.
Early replacement helps the laptop to resume operating normally and recover. CMOS is a very important component that maintains some of the sensitive operations that determine the condition and health of the computer.
Steps To Remove The CMOS Batteries
Finally, coming to the part where you will learn how to remove the CMOS batteries. Again, it is not very hard if you know the steps to remove it, the location of the battery, the required tools, and the procedure.
Here are the steps with detail that will help you a lot to remove the batteries successfully. Make sure to go through every step to remove them successfully. If you make the slightest mistake, then it might cause any other issues.
1. Open The Laptop
The first step to removing the CMOS battery from your laptop is to open up the laptop. To open the laptop, you will need some tools like screwdrivers. Next, turn off the laptop, and unplug it from the power source.
Now, turn the laptop over and find all the screws you need to open at the back. Now, unscrew all of them and remove the back case from the laptop. After you have opened the back, locate the CMOS battery.
2. Locate The CMOS Battery
One of the hardest parts of removing the CMOS battery is locating it. Mostly, it is located in the middle, near the motherboard bridge. So, look carefully at the motherboard to find the CMOS battery. You will recognize the battery easily as it is silver and round.
Most CMOS batteries are even smaller compared to a quarter. The thickness of the CMOS battery is around ¼ inch thick. Additionally, you might find 3V CRV032 written on the battery as well.
3. Removing The Battery
To remove the battery from the motherboard, you will need to follow a very easy process. Just undoing a small clasp of silver color will help you to remove the battery. All you have to do is pull the clasp up and slide out the CMOS battery. Also, while removing it, make sure to note or remember how the battery was set previously. It will help you to insert a new battery easily.
