How does my computer clock / calender stay working when I unplug it to go on holiday, does the C.P.U. have a rechargable battery, or what.

Zeus pally you unplug them for saftey reasons when the house is empty, for 2/3 weeks. You could say the same with a laptop with a flat battery that also looses all power.

cos it's got a little internal battery that keeps the clock going but eventually it'll stop (mine did after about 7 years), so before I can do anything I have to reset time and date or the computer's files get confused. It'd be easier to put new one in of course but it's a palaver on an apple. If I've switched computer off but it's still plugged in then there's enough juice to keep the clock going without resetting time.

There is a small battery on you mother board. The battery can last 3 to 5 years support your system time etc. After that you'll find it keeps lost settings and time, that time you need to change the battery.

There is a large button cell battery attached to the motherboard. This keeps the clock running and also ensures your usb devices, mouse etc, settings are kept running.

There is a little battery that keeps things ticking over while the computer is switched off.
