Welcome to Stack Overflow! This site is for programming questions, so your question about laptop battery is off topic. The associated site would be better for this question. – Greg Hewgill Dec 3 '10 at 11:47
If you want your battery to go dead, you should avoid plugging your laptop into the wall. – Marcelo Cantos Dec 3 '10 at 11:49
the suggestions of removing a fully charged battery to prevent it from receiving excess heat (in the links above) are all well and good, but doing that mitigates the advantage of having a built in UPS. – Xantec Dec 3 '10 at 13:32

If you have electricity available, you obviously want to use that. Your battery has a limited number of recharging cycles and should be used only when necessary.

In addition to Pekka's reply, a comment:

When the laptop is not on mains power, it may enter power-saving mode, which will degrade the quality of the display or other components. For better user experience, use mains power.
