Is it bad to keep a computer plugged in?
Keeping it maxed out @ 100% I heard was bad.... Does it really matter? I go through the process of draining and charging, and I had my computer for 7 months.... In fact I am draining it now... So is it true? Does it really hurt the battery? :) Thanks

It's good to put it on battery and drain it down from time to time. Keeping it plugged in 100% of the time isn't ideal.
I've found that different brands give different information to maximize the life of the battery. I noticed that the manual for your laptop says that there is information on maximizing the life of the battery here:
The Battery information section of the Help and Support Learning Center provides the following tools and information:
● Battery Check tool to test battery performance
● Information on calibration, power management, and proper care and storage to maximize battery life
● Information on battery types, specifications, life cycles, and capacity
To access Battery information:
▲ Select Start > Help and Support > Learning Center > HP Power and Battery Learning
Center.
Not sure if that will help...
Hi there
I think this is a hangover from the days of older batteries (NI CD / Nickel Cadmium)that used to have a "memory effect" which would "remember" the charging levels and deteriorate much more quickly. These batteries would hold their charge for shorter and shorter periods.
Modern batteries don't suffer from this memory effect but they still have a "Duty Cycle" (finite number of charge / discharge cycles) after which it will have to be replaced.
I don't think leaving a modern battery fully charged most f the time makes any difference at all although some people recommend that a BRAND NEW battery should be conditioned by charging and completely discharging a few times (3 or 4).
The Jury's still out on that one however.

Brand new modern Batteries have to be drained at least 3 times before reaching their best. Then it is a matter of customers action and how they use it in Power Plan settings. Drain it at least every month could be well...or everything two month but anyway it will die sooner or later. I don't give mine more than three years!
That's right NI CD / Nickel Cadmium had a memory effect...and on my first laptop, the battery dyed very fast due to me not caring.
I you think you're actual battery doesn't hold and it should, you can reset the Battery memory and Windows battery management by drain it 6 times the same day. This should erase old infos. I'm responding here to someone asking how to reset memory battery. There's not much to do...
Well, I have drained and changed my battery ever since I had this computer... (July 17th 2010) If I sat on my computer all day..
I think I could go about 6 charge cycles..
Personally, I keep the battery on my laptop fully charged, and in my laptop bag. WHen I am at home, i just plug straight into the mains, with no battery in at all.
I've always followed the HP recommendations and conditioned my battery when I first got my laptop (about 1 1/2 years ago) and then drained the battery to 10% every 7 - 10 days. Didn't help --- the battery only lasted a little over a year (and of course --- it didn't die until it was just out of warranty) and had to be replaced!
