Comos battery
is installed on the computer and laptop's motherboard. Its complete form
(complementary metal-oxide-semiconductor) is a technology used to make
microprocessor, microcontroller and other digital logic circuits. comos battery
ensures time and data of hardware and system which is part of a BIOS setting.
CMOS battery maintains its data even after the computer or laptop is shut down.

battery details
Life line of Cmos Battery is 10 years old.
BIOS settings store non -Volatile, which does not
require constant power to retain data. However, the motherboard uses RTC (real
time clock) because clock is always active, whether the computer is active or
not. It's not a quartz watch like a simple clock used by people. When the
computer or laptop is switched off, then the RTC Clock takes the voltage to
work with the COMOS Battery, and in this way, it also tells the timing correct
when opening.
But the main function of CMOS battery is to store
the BIOS settings of your computer. BIOS allows the system to recognize
available hardware and device drivers. If there is a problem with the CMOS
battery, the BIOS will not get all the data that is required and the computer
will not work as it should. There are some hints that will tell you about the
failure of CMOS batteries, here you can come with:
- An indicator of CMOS battery failure is that sometimes
your PC does not turn on for some time after the shutdown. If the driver
stops working, it can also be tied to CMOs.
- Getting "CMOS checksum error",
"CMOSerror" or other similar notifications while booting.
- Hardware issues are also indicative of the failure of
CMOS batteries. You can also see that your computer is having difficulty
identifying the keyboard, mouse or printer.
- If your computer has incorrect date and time
settings, then it may be due to CMOS battery failure. In addition, you can
notice that the date / time is being reset even after you have fixed this
in the BIOS.
