Should I keep my laptop battery in while plugged into the AC adapter? Why or Why not?

I've been googling this topic for awhile but so many websites/forums say different things. Some sites say its best to remove the battery while plugged in while some say its best to remove the battery. I have an HP and they are notorious for having bad battery life so I would like to optimize my battery. I read somewhere that HP suggests keeping the battery in with the AC adapter but they might just be deceiving and want the battery life to die faster so I could buy their batteries.

I have the HP dm3 (13 in) and its "supposed" to run ~5-6 hours on regular use BUT ive been using it for class and even on Battery Saver Option, the dimmest brightness, only Microsoft Word open, and very very light wireless it can survive a little over 3 hours on a good day (about two classes).

Keeping the battery in is the more convenient option but psychologically, I feel that its eating my battery life fast. which may in fact be true.

Moved to a more appropriate forum

Never had a battery last 5-6 hours. On my laptop it's not an option to remove the battery so I leave it in when hooked to AC power but will cycle the the battery once a week (unplug AC power and run the battery down to 5% power, then plug AC power back in and recharge). Li-on batteries usually only last 2-3 years of use anyways.

Most laptops do not let you boot up without the battery. Though, its generally good advice not to always keep your laptop hooked up to the AC adaptor 24/7, Id say drain that battery at least once a week (dont let it completly die, just get down to around 5%) and that should boost your battery life.
