There is no harm in what you are doing, in terms of the AC adapter.
Batteries ARE damage by being left in a laptop that is constantly plugged in. The culprit (and this varies by model) is a combination of slight overcharging and heat (from other components of the laptop, and possibly from being slightly but continuously overcharged).
The best scenario for a laptop that is used in a fixed location and doesn't travel is this:
-Remove the battery and store it in a drawer
-Get a good low-cost 300 to 500VA UPS (about $30 for an APC model ... sometimes less with rebates)
-Plug the power supply (adapter charger) into a battery backed up outlet of the UPS
-Give the battery a bit of "exercise" (use and recharging) about every 60 days.
-Battery makers recommend storing the battery in such cases with about a 60% charge

Here's a basic question. I have an Inspiron 2200 laptop..
I usually keep the AC Adapter (is that what it's called?) plugged in. So the green light on the adapter unit is always on.
I then connect the laptop when it needs charging (or just run it off the adapter when that's feasible).
Am I doing any damage by keeping it plugged in like that? Should I unplug the adapter when not in use??
Also, some of the time when I'm not using the laptop, I just keep it plugged in. I assume there is no such thing as it being overcharged and that the battery is not damaged in any way. Correct?
OK, that was two questions. Told you these were basic questions!
