Without shutting down XP

Laptop> set power setting for 'sleep' AKA 'Standby' when lid is shut.

Use either Hibernate of Standby. Set times in Control Panel> Power Options> Delete current power scheme> set new power scheme> Save.

Any of these will save your work, take you offline and keep the computer on a low power setting. IT will depend on which operating system you use as to which are available.
