when the pc is switched off its internal clock remains active as it has its own energy supply.(a battery).

It continues the time from when you disconnect and runs off the internal battery.

why it didnt help?what u didnt understand?:) The battery is using its charge while the pc is off,but when the pc is on battery is not being used so it should last for a long time. If you leave your pc off for a long time it means that the battery will last less.

There is a small battery (like a circle), it's responsible for letting the clock works either the PC is on or off.
