Hello, your question is very important. This has been observed on other models of laptops and there has, to my knowledge, never been a clear and well expressed explanation of this. In my personal opinion, laptop makers have done a poor job of explaining how the battery system works and what the user should do.
Some investigation shows that these types of batteries should not be left on a charger and definitely. Charging the unit actually generates some heat and represents a waste of energy. The battery is capable of keeping most of it charge without having a steady stream going into it 24 hours a day. There are some references to indicate that this procedure of a 24-hour charge may actually be dangerous or shorten the life of a lithium-ion battery.
However, if you think there's something wrong with your new laptop, take advantage of the warranty positions right away. As you may know, the laptop manufacturers have been very reluctant to identify battery problems in a timely manner. Sometimes users find himself outside of the warranty. When a danger has been identified by the manufacture. So, if you have doubts about the quality of the battery in your computer, contact the vendor or the manufacturer right away.
Now, having said that, there's just too much conjecture and speculation about how the battery systems are supposed to work in a laptop battery. This has got to be the fault of the manufacturers themselves of not making clear exactly how the systems are supposed to work.
The following observations are not my opinion nor are they conjecture. This is based on documented material that has been published in papers for engineers and technicians who work with the sort of thing. Normally lithium ion and similar battery types should charge to near full capacity in a reasonable amount of time. This is usually much less than eight hours and in some cases only takes four hours to go from almost 0 to near 100%. This has been documented elsewhere.
Sometimes it is specified that at least once you should leave the system on overnight for complete charge. Yes, that also has been documented. But it does not mean you would do that habitually. The document states this would be done the first time you use the device you would charge it overnight. From then on, only a short period of time should be needed to charge the unit to its full capacity.
While using the units at home or in your office you can plug the charger into the AC power in order to conserve battery energy and to provide a brighter display. Even so, you should unplug the charger from the wall after you shut down your computer.
I am aware that many others disagree with this and think you can just leave it plugged in all the time. But most of the real technical documentation does not support this conclusion.
Personally, I do justly the thing plugged in all of time. Because I'm too lazy to unplug it or I forget to unplug it. So I phoned the habit of just leaving it plugged in all the time until later I think about it and realize that I'm not doing the battery in a good by leaving it plugged in all the time.
I hope this is of some help to you. If you need links to documents that support this kind of reasoning, please some come back and say you'd like to see where this information is found.
