If the CMOS battery dies you lose the settings that are held in the BIOS (Basic Input Output System). These include settings such as date/time, boot order,etc.

What indicates that the charge on the CMOS battery could be getting low?
As far as I know, there is really no advanced warning, until the battery starts to fail. For example, on my computer, after using it for several years, the computer started to be unable to maintain the current time. I eventually figured out that this was a result of a weak CMOS battery.
What happens when the CMOS battery starts to die out?
You will lose all custom settings in the BIOS, and the BIOS will revert to the basic default every time the computer is restarted.
What should you do if you lose the settings saved in cmos ram?
Nothing, the computer will run fine on the default settings usually.
What should you do if you lose the settings saved in CMOS Ram because of the bettery going bad or being disconnected?
Reboot with a good battery and instruct setup to restore the default settings. Setup has to autodetect the hard drive present, and than you will need to set the date.
What keeps the CMOS data current and up to date?
The data is CMOS is on a chip called RAM. RAM will lose data when it loses power. A small battery on the motherboard is used to keep continuous power to CMOS when the PC loses power.
Will you lose your computer settings when replacing the battery on a 2004 jeep liberty?
Yes.
Why you are using cmos battry?
For starters, CMOS stands for Complementary Metal Oxide Semiconductor. CMOS is used in a form of non-volatile memory. To be non-volatile means means that it will not lose the data, even if the power supply dies or the power goes out. The CMOS battery also has a cool little trick it does - it tells time for your computer! That's right, at the bottom right (or upper right, possibly, depending on your liking of the Windows task bar) where it states what time it is, that is powered by your CMOS battery. Interestingly enough, it involves half-life, the process is really complicated and beyond my reach, however the substance that makes this half-life possible is completely natural! Thank you, nature!
What should you do if you lose the settings saved in CMOS RAM because of the battery going bad or being disconnected?
Data saved in cmos ram cant recovered if ram crashes suddenly but in case bettery or power failler 1) dont eject the ram runddnly wait for halting .2) use alternative system for power .3)detach the ram and place it in another ram reading system and fatch the data.
How is CMOS RAM able to hold data even when the power is off?
CMOS is not RAM. While it is memory, unlike main system RAM, CMOS is very tiny and only holds the BIOS configuration, nothing else. RAM is made from transistors and capacitors, which must be recharged. CMOS is made from several transistors wired as flip flops. It only needs a tiny amount of power to hold its data, and that comes from a small battery. If you remove the battery, it will lose everything.
How do you break a password on a laptop?
One can reset their Compaq PC's start up password by removing and returning the CMOS battery on the system board or shorting its terminals. This will cause the computer to lose all BIOS settings including the start up password.
The first component affected by a motherboard battery failure is?
assuming you mean the cmos battery on the motherboard itself, the first component to be affected will be the motherboards bios chip since that constantly needs power from the battery to run meaning it will lose all configured data stored and you may also notice an incorrect date and time on your device since it uses the cmos battery to keep track of time and date even when the device is "off"
Radio problems after changing the battery in a 1998 cirrus?
there is no problem you just lose all preset stations and any equalizer settings everything returns to default settings after a power loss you must reset all settings manually.
