Understanding CMOS Battery, CMOS Battery function and CMOS Battery working

Complementary Metal Oxide Semiconductor or what we are familiar with the term CMOS battery is one of the computer hardware similar to battery watch where this hardware is enabled and installed on the board or mainboard to be utilized by the computer's BIOS system.

The purpose of applying cmos battery is that the computer system can remain active and running even in the absence of an electric current. CMOS batteries are included in the type of chip with semi-conductor type used for data storage and this type of chip does not require an additional / external power.

In addition to the above explanation, there is also an explanation if this CMOS battery is often used to refer to a battery-powered chip found on many personal computers to function as a medium for storing some basic information, such as date, time and system configuration settings required by the input system / basic output (BIOS) to initiate computer activity.

CMOS can also be called a battery used by the BIOS to store its settings and remain active in the absence of electricity, a type of semi-conductor chip that stores data without requiring external resources.

Main function of CMOS Battery

• CMOS Battery serves as a device capable of storing time settings on a computer or other term can be called Time Setting, where setting is what will determine a performance for your computer system
• It functions as a medium for storing BIOS settings
• Serves as a medium that determines a computer system in order to perform a Backup & Restore and perform an update
• Gives power to the motherboard in recognizing the installed configuration, when the CMOS does not or does not yet get power from the power supply
• Storing data without requiring external power
• Gives power to the BIOS
• And a very important CMOS Battery Function is storing the BIOS Configuration

How the CMOS Battery Works

CMOS battery basically functions for storage of a diagnostic program, configuration program, sychronization of files that have been created will not be erased when the computer device has been turned off, as well as a media to display a day, date and time information.

You need to know that CMOS has a main character, the CMOS possesses a fairly high noise and the use of a low static, the power taken when the transistor inside the CMOS is doing the displacement from the position of life and death.

At the time of power supply on the computer device is on, CMOS batteries have an important role to do some checks to be ascertained if the computer system is really running well and do a calculation on the use of RAM. After the CMOS batteries have finished doing the main check above, and then the CMOS battery performs an examination of the RAID configuration, checks the format of the hard drive, checks for the presence of a pheriferal, and performs a boot boot preference.

Keep in mind, if you are going to do a change in CMOS, it would be nice to study the problems associated with CMOS Battery, because if you do a configuration on CMOS not in accordance with what is recommended, then your computer system can not be stable, causing a damage to the system and the thing that often happens when one make a change in the CMOS, your computer device will not be able to boot at all.

CMOS Treatment and Repair Steps

A. CMOS Causes Not Working Well

-It is likely that the CMOS battery you installed has been weak, so it can no longer support CMOS power when the computer is offline or off.

-The habit of using equipment such as USB Flash Disk, External Hardisk which is unplug without using Safely Remove Hardware feature, which activities like this can lead to software installed and in the data by CMOS will be stored, then when the computer is on again CMOS can not find the data The hardware.

-The second possibility that could happen is due to virus attacks that attack regystry windwos or other OS registry related to CMOS so that between CMOS and windows can not sync.

Symptoms of the frequency of the computer is turned off without going through the Shutdown feature, which resulted in the system not storing CMOS settings, and CMOS is ready to save the component settings because it is turned off unexpectedly.

When CMOS is disrupted then the use of the computer is not stable, although all computer components are not damaged.

B. CMOS Damage Indicators

-A fairly severe damage indicator is that no image appears at all on the screen when it is turned on or when restarting, even if you are sure that all devices in the system are still operating. If the indicator of this kind, many also suspect if the other hardware has problems like power supply, VGA Card, Processor or RAM that is no longer strong support system work, but you need to know that this is also often caused by CMOS holder that is less fit.

-The second indicator that indicates your CMOS battery is in trouble is when you often see "CMOS Checksum Error" on the screen when you start the system for the first time or when you restart. If you receive a notif or indicator like this, there is obviously something wrong with the CMOS you are installing.

-The third indicator is the date setting in the wrong BIOS. You need to know if the battery is "soak or weak", although you return to the correct settings, dating system still experience ganggguan. If you have this, it can be ascertained its CMOS is not working properly again, then the solution please you replace with a new CMOS
