Is it wise to leave a (fully charged) battery in a laptop while it is plugged into ac power plug. Will hurt or dimish the battery. Or is best use the ac plug and take the battery out while at home. I have a duo core chip.

The laptop charging circuit automatically limits the charge when the battery is fully charged, there should be no issue in leaving the battery in. Also, LiIon batteries don't like to be fully discharged, they're not like NiCad batteries, charge/discharge cycles are NOT good for lithium batteries.

This is what I believed as well. However, I just read in Laptop magazine a few weeks ago that all laptop users should allow the batteries to discharge completely on a regular basis.
