well,
how much power(watt) does a normal laptop needs?

is it possible to use external batteries with the laptop..or is there provision like mobile where we can have any numbers of batteries..charge batteries with out mobile...and if one finishes put another one...
is it possible with the laptops...?
are there any brand or technique for it?

thanks

^^ all the laptops (except macbook air and new macbook pro) comes with external batteries. You can replace the batteries yourself, carry new batteries.

how much power a laptop needs depends on the configuration.

thanks was really helpful

no. it won't void the warranty. for most of the laptops, the battery is at the bottom on the rear. There will be one or two locks (kind of switches). turn them to one side and remove the battery.

here is an example for Lenovo T43 laptop:
