Yes but you will reduce its life a little if you usually just leave the laptop parked at home. For maximum life of the battery (not run time, but the time until you need a new battery) you can remove the battery and store it if you will not be using it for a week or more. Run it down to 40-60% and store it in a cool dark dry place.

 

Every time you turn the laptop off and back on the battery drains just a little and then it charges back up when you turn it back on. The smart chip counts that as a cycle and you only get so many cycles.

You should not. Disconnect the moment you shut your laptop down. The power converter works all the time when connected to AC power; by keeping it connected you will shorten its life.

If you leave the AC adapter plugged in with the laptop off it will draw a very small trickle charge through the adapter, not enough to cause any harm. Electricity requires a  complete circuit and if the laptop is not drawing much power, the adapter is not working hard. By this logic we would unplug a desktop computer, even when the computer is off, so the internal power supply would last longer. Not necessary and nobody does it.

February 2014.

 

Since some years Ago I leave my HP laptops (and Mac) all the time connected for weeks in my Office and at home and I have not issues with the battery or the laptop. The battery life is normal no less no more...

 

 

Para mis amigos en español.

Dejar la laptop conectada todo el tiempo a la electricidad, Yo dejo mis laptops (HP y MAc) conectadas todo el tiempo y no he tenido ningùn problema, no se reduce el tiempo de vida de la baterìa ni tiene ningùn problema la computadora

 

regards / saludos
