I've not seen a laptop that won't run without the battery installed in
quite
some time.
Batteries have a limited number of charge/discharge cycles. If you don't
need to run on the battery, you shouldn't. Staying plugged in does not
overcharge or damage the battery.
Lithium-ion batteries (used in all modern laptops) should not be
discharged
down to nothing. Laptops will turn off before discharging the battery too
far, but even when off continue to use a small amount of battery power.
If
a laptop is left on the shelf, never plugged in, the battery can be
damaged.
NiCad and NiMH batteries prefer to be fully discharged before being
charged
again.
I hadn't heard of that before that you shouldn't discharge the Lion
batteries fully. So I went googling and found the following article:

By the way, removing the battery while on A/C power depends on the laptop.
I'm able to do this on my Acer Travelmate 250. It depends on whether the A/C
plugs into the laptop or the battery, in my case it's the former.
