That definition applies to versions of Windows prior to Vista. Vista uses a
sleep or hybrid sleep mode. Sleep mode is what the majority use, and likely
yourself as well since the contents of ram are lost when you remove the
battery. The hybrid mode is closer to the true hibernate, but is disabled on
most systems - particularly laptops. Regardless of which you use, some
components will remain charged by a trickle from either the psu or cmos
battery, and many support a 'wake' feature that can reinitiate the os.
