In my opinion, your info is 100% correct!! I too beleive that removing the bat when on AC is the solution to save battery life. Unfortually i learnt the hard way and ended up having to buy a new battery to replace my old one which i did not adopt this technique of removing when on AC.
Your analogy is false. it doesn't count as a cycle every single time you use the battery. For example, if you charge the battery, using it for 1 minute, then charge it again, it doesn't 'count' as a cycle - modern LiIon batteries JUST DONT work that way. The charging circuitry in your notebook DOESN'T just dump power into the battery all the time - if it did that, you'd find a leaking battery the first time you left it in for a few hours.
If you want to know what WILL kill your battery, its the following: Discharging below 3%. Just dont do that,and you battery will last for its designed period.
I've replied to your post in the First Time Users forum with a little more depth as to WHY it doesn't work this way. No reason for you to be embarrased, because battery chemistry is a complex (but cool!) topic...

This is along the lines of the age old question “Should I turn my computer off at night (I do)
What about the AC Adapter? Is there any perceivable advantage to unplugging the AC Power supply (With the green LED on) when the computer is shut down?
I would think that the only power being used is the miniscule current needed to power the LED, but what about heat?
On my Desktop I simply turn off the surge protector, but the Inspiron is plugged into another surge protector that is not easily accessible
I realize this is less-than a critical issue.

Srry took so long to get back to you - your post got lost in the pile!
leaving it plugged in is fine. No difference between that and unplugged. Things only generate heat when they use power, so if its not carging and not running, no heat will be generated. The power used by the LED is miniscule.
Theres also no reason to turn of the power strip on your desktop either. In fact, I would recommend against it, so that your CMOS battery is constantly being charged.
concerning the issue about leaving the battery in.... you said the circuitry keeps it from overcharging but what i have heard the problem is is that the battery slowly discharges on its own then when the circuitry detects that the battery is not at 100 percent (when it drops to 99) it charges again to 100 percent and this type of cycle is what causes problems

Thanks. My uncles IBM ran out of battery power in less than 5 months because of this. I should post this in the First time Users board. i'll do that.
