If your computer is running slowly or shutting down unexpectedly, it might be time to change the battery in your CPU. Here’s how to do it: First, find the right replacement battery for your model computer. You can usually find this information online or in the owner’s manual.
Next, shut down your computer and unplug it from any power source. Then, open up the case and locate the battery. Once you’ve found it, remove the old battery by disconnecting the cables or clips that hold it in place.
Finally, install the new battery by connecting it to the appropriate connectors and closing up the case.
If your computer is running slowly or acting strange, one possible culprit could be a dying battery. The good news is that replacing the battery in a CPU is a pretty simple process.
Here’s a quick guide on how to do it:
1. First, shut down your computer and unplug it from any power source.
2. Next, open up the case and locate the battery. It will usually be attached to the motherboard in some way.
3. Once you’ve found the battery, gently remove it from its socket. Some batteries may be held in place with a clip or screw; if so, simply remove this before proceeding.
4. Take your new battery and insert it into the socket, making sure that the + and – symbols line up correctly. If there’s a clip or screw, reattach it now.
How Do You Remove a CPU Battery?
A CPU battery, also called a CMOS battery, is a small coin-shaped battery found on the motherboard of your computer. The battery provides power to the BIOS chip so that it can remember your settings even when the computer is turned off. Over time, the battery will begin to lose its charge and will need to be replaced.
Here are instructions for replacing a CPU battery:
| Step one | Shut down your computer and unplug all cords from the back of the tower. Flip the tower over so that you can see the bottom of it. |
| Step two | Find the small, round, silver battery on the motherboard and gently pry it out with a flathead screwdriver or your fingernails. The old battery may be soldered in place, in which case you’ll need to use a soldering iron to remove it. |
| Step three | Take note of which way the old battery was inserted into the socket before removing it so that you can insert the new one correctly. |
| Step four | If there is any residue left on the contacts from the old battery, clean it off with a cotton swab dipped in rubbing alcohol before inserting a new one. Gently insert the new battery so that it snaps into place and replace any screws or plates you removed accessit. |
Can I Replace My Computer Battery Myself?
As battery technology continues to advance, the need to replace your computer battery may arise less often. If you do find yourself in need of a new battery, you might be wondering if you can replace it yourself. The answer is: maybe.
It depends on the type of laptop you have. Some laptops, like many MacBooks, have batteries sealed inside with special screws that require a special tool to remove. Other laptops, like many Dell models, have user-replaceable batteries.
If your laptop has a user-replaceable battery, the process is fairly straightforward: just unscrew the old one and screw in the new one.
But there are a few things to keep in mind before doing so:
- First, make sure you get the right replacement battery for your specific model of laptop. Not all batteries are created equal and using the wrong one could damage your computer or void your warranty.
- Second, when replacing the battery, be careful not to damage any other components in your laptop while taking out or putting in the new one—a static discharge from your body could fry delicate circuits nearby.
- Finally, it’s always a good idea to discharge your old laptop battery completely before removing it (to minimize fire risk) and calibrate your new one according to manufacturer instructions after installing it (to maximize its lifespan).
- So if you’re feeling handy and want to save some money by replacing your own laptop battery instead of paying someone else to do it, go for it—just be sure to proceed with caution and follow all safety instructions closely.
Can I Replace CMOS Battery Myself?
Yes, you can replace the CMOS battery yourself.
Here’s how:
Step One
First, find the old battery and note its voltage and polarity. You’ll need to purchase a replacement battery that has the same voltage and is of the same type (alkaline, lithium, etc.).
Step Two
Next, locate the CMOS battery on your motherboard. It’s usually a small, circular coin-shaped component.
Gently pry it out of its socket using a flathead screwdriver or other tool. Install the new battery in the socket, making sure to observe proper polarity (the positive and negative terminals should match up).
Final Step
Once the new battery is in place, reassemble your computer case and plug it back in.
Your computer should now be working properly again!
Is It Worth Replacing a Computer Battery?
Assuming you are talking about a laptop battery, the answer is usually no. A new battery typically costs $100 or more, and only offers a few years of use before it needs to be replaced again. Unless your laptop is very old, it is probably not worth spending the money to replace the battery.
On the other hand, if your laptop is several years old and the battery is starting to lose its charge quickly, replacing it may extend the life of your computer by a year or two. If you plan on keeping using your laptop for several more years, then it may be worth investing in a new battery.
CMOS Battery
The CMOS battery is a small, round, flat battery that looks like a watch battery. It powers the Real Time Clock (RTC) and CMOS memory on your motherboard. The RTC keeps time even when the computer is turned off, and CMOS memory stores BIOS settings like system passwords.
If you’ve ever noticed your computer’s clock resetting itself after you unplug it from the wall or replace its batteries, that’s because it’s using the CMOS battery to stay powered. The CMOS battery also comes into play any time you change BIOS settings – if you’ve ever had to re-enter your date and time after starting up your computer, that’s because the power for those settings comes from this little battery as well. You can check the CMOS battery in the BIOS.
Fortunately, replacing the CMOS battery is a pretty easy task:
- You’ll just need to unscrew a couple of things to get access to it – usually just a few screws on the back or bottom of your computer case will do the trick.
- Once you have access to where it sits on your motherboard, carefully remove the old one (being careful not to touch anything else in there) and put in a new one – again, taking care not touch anything but the edges of the new battery.
- Put everything back together, screwing everything in tightly so nothing can come loose, and you’re all set!

| Step four | Finally, reattach all of the cables and power on your computer. If everything goes well, you should now have a working computer with a new CMOS battery! |
CMOS Battery on the Motherboard
If your computer won’t start, one of the first things you should check is the CMOS battery on your motherboard. The CMOS (Complementary Metal Oxide Semiconductor) battery provides power to the Real Time Clock (RTC) and settings stored in the BIOS. If the battery is dead, the clock will reset itself, and default BIOS settings will be used.
In this blog post, we’ll show you how to check if your CMOS battery is dead, and what to do if it is.
To check if your CMOS battery is dead:
- you’ll need to open up your computer case and take a look at the motherboard.
- On most motherboards, the CMOS battery will be located near the RTC chip. It will look like a small coin-sized button or disc. Once you’ve found the battery, use a multimeter to test it for voltage.
- A good working battery should have a voltage of 3 volts or more. If it reads 0 volts or close to it, then the battery is most likely dead and needs to be replaced.
What to Do If Your CMOS Battery Is Dead?
If your CMOS battery is indeed dead, don’t worry – it’s an easy fix! Just head over to your local electronics store or order one online and replace it with the old one. Once you’ve done that, all your BIOS settings should be restored back to normal.
Motherboard Battery Dead Symptoms
If your motherboard has a dead battery, there are a few things you might notice:
| Number one | First, your computer may not start up as quickly as it used to. This is because the battery is responsible for keeping the date and time correct, and without it, your computer will need to retrieve that information from the internet or another source every time it starts up. |
| Number two | Additionally, you may notice that your computer’s CMOS settings have reset themselves – this is also due to the loss of power from the battery. |
| Number three | Finally, if your motherboard uses a lithium-ion battery (most do), it will slowly lose its capacity over time until it eventually needs to be replaced. If you suspect that your motherboard’s battery may be dead, check for these symptoms and replace the battery if necessary. |
Where is the CMOS Battery Located?
The CMOS battery is located in the computer’s motherboard. This battery provides power to the computer’s BIOS, which allows the computer to keep track of time and date even when it is turned off. The CMOS battery can be found in different locations depending on the make and model of the computer, but it is usually located near the keyboard or CPU.

CMOS Battery Price
A CMOS battery is a small, coin-shaped battery that provides power to a computer’s motherboard. The battery helps to keep the date and time settings on the computer accurate. It also helps maintain other settings in the BIOS, or basic input/output system.
When CMOS batteries go bad, computers can experience a number of problems. The price of a CMOS battery will vary depending on the brand and model of the computer. For example, a Dell Inspiron laptop may use a different type of CMOS battery than an HP Pavilion desktop.
Some computers may have proprietary CMOS batteries that can only be replaced by the manufacturer. When shopping for a replacement CMOS battery, it is important to know the make and model of the computer as well as the voltage and amperage requirements of the original battery. Many electronics stores carry generic CMOS batteries that will work with most computers.
These generic batteries are often less expensive than those made by specific manufacturers.
