Laptop's Battery Charge

In this article, I will explain what's in my mind when someone wanna charge his/her notebook. In fact,there's 3 possibility when someone wanna charge his/her notebook.

First, replug adapter whenever the battery going empty.
Second, ALWAYS plug the adapter with battery installed.
Third, plug the adapter with battery uninstalled.

So many opinion on these 3 points. I will explain what's my opinion.

First,
Like a cellphone, just charge your noteboook whenever your battery going empty. I believe it's only works with any notebook that stand more than 3 hours. Otherwise, you will feel bothered with this, and eventually leave the adapter attached. I'm sure many people do this in the first time. So, I don't think this option will be yours.
Conclusion : Effective, but trust me, you will sick with it.

Second,
Leave the adapter plugged while your battery attached. I think this is the best option. When your lights off, leave the rest to your battery. It'll backup your notebook, and you still have much time to save your work and shut down your notebook. The best features from your notebook is when your battery under 10%(adjustable), you can set it what you want your notebook do, is it "Standby" or "Hibernate". You can find this option in "Control Panel - Power Options"
Conclusion : Safety first... and I very vary recommend this option.

Third,
Leave the adapter plugged while your battery not attached.... I think this will be worst option. Just consider this illustration :
When you work with your notebook, copy-paste any file to your FDD, download any file, in another word "hardisk is working", the lights goes off or somebody accidentally pull out your adapter. Your notebook will be forced to turn off and in the end, there will be much problem with your hardisk, or maybe BSOD (Blue screen of death), power failure, etc.
Conclusion : I don't recommend this option

EXTRA INFO :
When your battery is full, your adapter will be change the path, from the battery to the notebook, you can see in your icontray, when your battery attached with the adapter plugged, your "power manager" smartly change the path into ac power

Different with cellphone's system, cellphone's power only depend to it's battery, so, when your battery 100%, when the power decreased, the adapter will force to charge the battery, in the end your problem will be "bleeding battery".
