Swap the battery while the power is on. So long as you are careful not to drop the battery, you will be fine. The battery is only there to back up the CMOS and keep the time correct when the power is off.
Can I remove CMOS while PC is on?
Prominent. Nope, just did it twice. PC is completely fine and boots up properly. I still would recommend doing it though as it didn’t clear cmos until the PC was off.
What happens if I remove the CMOS battery?
Removing the CMOS battery will allow your computer to run however, you will lose the date and time settings, the computer will boot with default BIOS settings or you will have to choose the drive that the OS is installed every time you start your computer.
Can computer turn on without CMOS battery?
You can generally run your PC without the CMOS battery as long as your default CMOS parameters are compatible with the operating system, or as long as you manually set the appropriate CMOS parameters after every time the system loses power.
Is it safe to replace CMOS battery?
Generally the CMOS battery lasts for a decent duration of years together. You should keep an eye on the system date. If the system date keeps resetting to a previous value on a reboot, even after you setting it up, it’s time to replace the battery.
Why PC turn on but no display?
If your computer starts but displays nothing, you should check is if your monitor is working properly. Check the power light of your monitor to verify that it’s turned on. If your monitor won’t turn on, unplug the power adapter of your monitor, and then plug it back into the power outlet.
How long does a CMOS battery last?
CMOS battery
This cell battery has an estimated life of 3 years when power supply unit (PSU) is unplugged or when the PSU power switch is turned off. This battery type, unlike the Lithium-ion battery, is not rechargeable and trying to do so may result in an explosion.
Does removing the CMOS battery reset BIOS?
Not every type of motherboard includes a CMOS battery, which provides a power supply so that motherboards can save BIOS settings. Bear in mind that when you remove and replace the CMOS battery, your BIOS will reset.

Can a dead CMOS battery cause blue screen?
Some of the signs of a failing CMOS battery:
Your computer will sometimes turn off or not start and will generally show startup errors explaining an issue with the battery. (CMOS checksum and read error) Drivers may stop working, it can trigger driver blue screens and crashes.
Is resetting CMOS safe?
Clearing the CMOS should always be performed for a reason – such as troubleshooting a computer problem or clearing a forgotten BIOS password. There’s no reason to clear your CMOS if everything is working properly.
When should I replace CMOS?
It is recommended that you change the CMOS battery every 5 years. Open the BIOS screen and note all the information on a piece of paper. It’s important that you don’t make any modifications.
Can RAM cause no display?
Can RAM cause my display to go black? Yes. Without RAM, your computer can’t function, which means your display will be black when you turn it on. If you think this is the cause of your display problem, try reseating the RAM or installing new ones.
What type of battery is a CMOS battery?
CR2032
A coin-cell battery (CR2032) powers the real-time clock and CMOS memory. When the computer is not plugged into a wall socket, the battery has an estimated life of three years.
How do I know if my power supply is going bad?
Symptoms of a failing computer power supply
Random computer crashes. Random blue screen crashes. Extra noise coming from the PC case. Recurring failure of PC components.
What kills CMOS battery?
Also, the temperature inside computers is usually increased, when compared with the temperature in the typical office or home – increased temperature also leads to the increased self-discharge rate. So, constant current drain and increased temperature eventually kill the CMOS battery.
How can I make my CMOS battery last longer?
You need to use the computer regularly to extend the life of the CMOS battery. The computer power supply increases the availability of a standby current and hence increases the life of the battery. If the computer is not plugged in regularly, the life of the battery is normally 3 years.
What does CMOS stand for?
Complementary Metal Oxide Semiconductor
Like CCDs, CMOS(Complementary Metal Oxide Semiconductor) sensors are semiconductor image sensors that convert light into electrical signals.
Are all CMOS batteries the same?
Today, just about every PC motherboard made today, and since about 1992, use the CR2032. From about 1981 to 1992, they often use some variation of a larger 6 volt battery (about 2 inches x 0.5 inches by 0.5 inches) that plugged into the motherboard.
What is CMOS battery failure?
The most common symptom of CMOS battery failure is incorrect or slow system date and time in the BIOS, loss of BIOS settings when the computer is powered off, time-of-day clock stopped error message and so on. If the CMOS battery is out of charge, the BIOS settings will be lost when the computer is powered off.
Where do I find the CMOS battery?
Find the CMOS battery, which is located on the right side of the motherboard. It will look like a quarter. Take note of the orientation of the battery facing up (+ or -). On Creation Stations, the direction of the battery has the + (positive) side facing up.
