Does it contain any inbuilt watch and also a software that reads the time from the watch and displays it on the screen? Please clarify my doubt.

    You can see a small battery placed in your motherboard.. this battery last for 3 years and keep the time...

    It's called a CMOS battery and it will eventually go bad and need to be replaced. When your system stops keeping the date and time, that means it's time to replace.

    There is a battery, about the size of a dime (like a watch battery) on the motherboard of your computer.

    Actually it's call a CMOS battery. In earlier computers, it didn't just keep track of time but also kept track of important booting information. When some older computers have a hard time booting and you have to reconfigure things each time, the first thing you would do is see if it was losing time - because it was a sign you needed a new battery. With the newer computers, I believe it just tracks time and date....

    all computers have built in battery.

    Its due to CMOS Battery provided by your motherboard manufacturer. Important system settings like Date, Time, Booting Sequence, Numlock On/Off at startup etc. are stored in CMOS. When your PC is switched off, these settings are saved powered by the battery.

    There is a component on the motherboard called "CMOS." CMOS is the component which is responsible for keeping time for the computer. CMOS has its own battery; therefore, it doesn't need the computer to be on for it to keep time.
