The Myth of Leaving it Plugged In
The aged old myth of leaving your laptop plugged in forever and a day remains strong even today.
Many people claim that this is an old adage that doesn’t apply to modern Li-Ion (Lithium Ion) batteries, however there is just as many people who disagree. Even Apple agree with an official statement on their site about not leaving your laptops plugged in all of the time:

However, an article on the Dell website doesn’t recommend the same thing – In actual fact it neglects to comment on what you should do once your notebook is fully charged. HP even circumvent the topic in their article.
