Should laptops remain plugged in when their battery is 100% charged?

I want to expand the lifetime of my battery which is a 6-cell lithium ion. I've read somewhere for Li-Ion cell phones that we should let the battery die before charging it. Is that the same with my laptop? My laptop is always plugged in. Should I not use it plugged in and keep on using it on battery and charge when low?

Lion batteries can be damaged by draining them completely before recharge, that method is for old Nicad/Nmhi batteries.
