Default Leaving laptop plugged in?

I heard that leaving a laptop plugged in for a long time isn't good for it. True? Why?

Unhappy i dont know...

personally, i would think it depends on how you use the laptop

if you use a laptop like a desktop computer (I.E. always leave it on, never take it around) then it might make the battery leak)

if you just recharge the battery once in awhile it shouldnt do anything bad

I would say that if anything, it would only mess up the battery. if you plug it in when it's half charged all the time, it's not good for the battery

Crap. That explains why I now only get about 20 minutes of life on a charge...

Yea, I allways let the batteries in my phone or something else completly die before I charge them because they have a chip in them that remembers how long it took to charge it last and it cuts the circuit when it reachs that time the next time or something..... But meh....

Leaving your laptop plugged all the time is not good for 2 reasons:
1) battery is aging MUCH faster when it's warm (warmer than room temp)
2) li-ion/polymer batteries does not "like" to be in 100% charged state. It looses it's capacity quickly.

If you want to use your battery when you need it - Better charge it to only 30-40%, unplug it , and store in cool place.

Yeah, I have, but I thought that was mostly in NiCad not Lithium ion.

Lithium and NiMh batterys are not really affected by memory at all.
