CMOS RAM is Powered by a trickle of electricity from a small battery located on the motherboard or computer case, usually close to the firmware chip, so that when the computer is off, CMOS RAM still retains it's data.

Where does the CMOS RAM receives its power when the computer is not turned on?
The CMOS is run off of a battery on the motherboard.
How is the CMOS RAM chip powered when the system is turned off?
The coin-cell battery powers CMOS RAM when the system is turned off.Pg.162: A+ Guide to Managing and Maintaining Your PC. Jean Andrews 8th Edition.
Memory that loses its contents when the computer power is turned off?
Random Access Memory (RAM) is the kind of memory that loses its content when the computer power is turned off.
Is the RAM volatile storage that is erased when the power is turned off?
Yes
When you restart your computer the error message cmos setting wrong and cmos cheksum bad comes up?
Chances are that the CMOS Battery on the motherboard is dead and needs to be replaced. Without this battery, the computer can not remember the CMOS settings when the power is turned off.
How is CMOS RAM powered when the system if unplugged?
By an external battery that is not connected to the PSU and only used for the CMOS RAM, this could be in the form of a Coin cell Battery (a silver coin shaped battery) or a barrel soldered battery. This is why the date and time settings are not lost when the computer is unplugged.
What retains the data even when the computer is off?
The internal hard-drive, USB flash drive, external hard-drive can all be used to save data, provided the document (for example) has been saved occasionally while the document was being worked on. If working in RAM (Random Access Memory) the data is lost as soon as the power is turned off, as RAM is a volatile memory, unless a battery back-up system is used.
Why does a computer turn on if the CMOS battery is removed?
Removing the CMOS battery will not prevent the computer from turning on, it will only cause the information in the CMOS RAM to be lost (while the computer is turned off). When you turn on the computer after the CMOS battery has been removed, while it will turn on it will most likely not boot the OS correctly but will stop in the BIOS and require you to completely setup the CMOS parameters again before you can tell it to continue..
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.
Memory that loses its contents when power is lost?
Random Access Memory (RAM) is the kind of memory that loses its content when the computer power is turned off.
What is a technical name for the volatile computer workspace that is erased whenever the power is turned off?
Three letters: RAM
What component is necessary to save system settings whe you power off the computer?
CMOS battery
