I recently bought a new Samsung R480. It's capable of handling games pretty fairly cause of the nVidia GeForce 330m discrete graphics card. The problem is that it can only last on battery for approximately 2 hours. My question is whether or not it's okay to leave the battery in while I use it with the adapter plugged in.
The difference of my question with other questions very similar to this is that Samsung has a feature that lets the laptop charge only until 80% supposedly prolonging battery life. Also, when I check the battery icon on the taskbar, it says that it's not charging, which i assume to mean that it's not wasting cycles.
Answer
Yes, its fine to leave it plugged in.
Nowadays, manufacturers use very advanced circuitry when it comes to regulating batteries. This is to prevent things like overcharging, being given the wrong voltage, or wasting cycles etc.
As soon as the battery is charged, the circutry should stop supplying power to the battery and the laptop should take power from exclusively from the mains.
So essentially when the battery is charged, it should'nt be getting used by the laptop, which is the same effect as physically taking it out. (Which is likely why its showing 'Not Charging', because the battery is full and it has, correctly, stopped charging it)
This is not so common in older (3+ years old) laptops though, where you will find leaving it plugged in for extended periods of time (weeks or months) will degrade battery performance. This is because the charging circuitry used was not as smart.
