Do All Clevo Laptops Have CMOS Battery

Welcome to this informative article on Clevo laptops and their CMOS batteries. As a laptop user, you may have heard of the term “CMOS battery” before, but do you know what it is and why it’s important?

In this article, we will explore the role of a CMOS battery in a laptop and specifically focus on whether all Clevo laptops have one.

We will also provide you with some tips on how to check if your Clevo laptop has a CMOS battery and what to do if you need to replace it.

So, let’s dive in and learn more about this essential component of your laptop!

What is a CMOS Battery?

A CMOS battery, also known as a motherboard battery or RTC (Real Time Clock) battery, is a small coin-shaped battery that powers the CMOS memory chip on a computer’s motherboard.

This memory chip stores important information such as the system’s date and time settings, BIOS configuration settings, and other hardware settings.

Without a functioning CMOS battery, a computer may experience issues such as incorrect date and time settings or failure to boot up properly.

It is important to note that not all laptops have a CMOS battery, but most desktop systems do .

In recent years, some laptop manufacturers have opted for fixed (soldered) RTC batteries and non-volatile flash RAM to store EFI (Extensible Firmware Interface) settings instead of using removable CMOS batteries .

Does a Clevo Laptop have a CMOS Battery?

Many modern laptops, including some Clevo models, do not have a removable CMOS battery.

Instead, they use a fixed RTC (Real-Time Clock) battery and store the EFI (Extensible Firmware Interface) settings in non-volatile flash RAM .

However, some older Clevo laptops may still have a removable CMOS battery that can be replaced if needed.

It is important to note that even if a laptop does not have a traditional CMOS battery, it still has some form of backup power to retain BIOS settings when the laptop is turned off.

This backup power can come from the main laptop battery or other internal components .

If you are unsure whether your Clevo laptop has a CMOS battery or not, there are ways to check which will be covered in the next section.

How to Check if a Clevo Laptop has a CMOS Battery

To check if a Clevo laptop has a CMOS battery, you will need to locate the motherboard of the laptop.

The CMOS battery is usually located near the motherboard and looks like a small silver coin. If you are unsure where the motherboard is located, you can do a quick Google search to find out.

Once you have located the motherboard, look for a round silver object that resembles a coin.It is important to note that not all laptops have a removable CMOS battery.

Some modern laptops have fixed (soldered) RTC batteries and store their settings in non-volatile flash RAM .


However, most Clevo laptops still have removable CMOS batteries that can be replaced if needed.

If you are unsure whether your Clevo laptop has a removable CMOS battery or not, it is best to consult with an expert or refer to the manufacturer’s manual.

CMOS Battery Replacement for a Clevo Laptop

If you have determined that your Clevo laptop does indeed have a CMOS battery and it needs to be replaced, don’t worry! It is a relatively simple process.

First, you will need to locate the CMOS battery on your specific model of Clevo laptop. This can usually be found by doing a quick online search for photos of the motherboard or by consulting the user manual.

Once you have located the CMOS battery, carefully remove it from its socket. Take note of which side is facing up so that you can insert the new battery in the correct orientation.

You can purchase a replacement CMOS battery at most electronics stores or online retailers. Simply insert the new battery into the socket and press down gently until it clicks into place.

Finally, replace any covers or panels that were removed during the process and power on your laptop to ensure that everything is working properly.

If you are still experiencing issues with your Clevo laptop after replacing the CMOS battery, it may be time to consult with a professional technician for further assistance.


In conclusion, the presence of a CMOS battery in Clevo laptops is not a universal feature. While some models may have this component, others may not require it due to advancements in technology and design.

It is important for users to understand the purpose of a CMOS battery and how to check if their laptop has one, as well as how to replace it if necessary.

By following these steps, users can ensure that their Clevo laptop functions properly and maintains its settings even when powered off or unplugged.

Overall, while the absence of a CMOS battery may not be a cause for concern, it is always best to stay informed about the components and features of your device.
