A laptop computer has a battery that has a wonderful battery life. As long as you charge your laptop battery for the appropriate amount of time, then you can use your laptop without the need to plug it in for many hours. This will allow you to be free and not be tied to finding an outlet to plug in your laptop.
8 hours for the first time....1-2 hours afterwards is good enough..Charge until the battery is fully charged.Modern Lithium-ion batteries will not get over-charged (as long as the charging equipment is working properly). I leave my laptop in for weeks at a time with no detrimental effects noticeable.

Many laptop users have this question and we will answer it right now: The answer is: YES and NO, it depends on the situation. Having a battery fully charged and the laptop plugged in is not harmful, because as soon as the charge level reaches 100% the battery stops receiving charging energy and this energy is bypassed directly to the power supply system of the laptop.
