Does leaving the laptop charged up continuously (plugged in) extend the battery life of a laptop computer. Or should it be fully discharged and then fully charged each time?

No, in fact it causes a battery to have a shortened life span =- typically laptop batteries only last 15 to 18 months with daily uses and good recharge practice -
I ran a laptop Program at a large University and saw nearly everything that can happen to a laptop -
most vendors only warrant batteries for one year,

Do you mean to say that to leave it plugged in continuously shortens the battery life??

Apparently so.
Batteries need to be cycled; charged and discharged --- but not totally discharged.
Most batteries are rated for a certain number of cycles in their lifetime.
I was confined to a rehab facility for a few months and kept my cell phone plugged in all the time. I had to buy a new battery much sooner than usual.
The salesperson at the store said the shorter life was from keeping it plugged into the charger all the time.
