Since 1997, you’ve been coming to BarnesandNoble.com to discuss everything from Stephen King to writing to Harry Potter. You’ve made our site more than a place to discover your next book: you’ve made it a community. But like all things internet, BN.com is growing and changing. We've said goodbye to our community message boards—but that doesn’t mean we won’t still be a place for adventurous readers to connect and discover.

Now, you can explore the most exciting new titles (and remember the classics) at the Barnes & Noble Book Blog. Check out conversations with authors like Jeff VanderMeer and Gary Shteyngart at the B&N Review, and browse write-ups of the best in literary fiction. Come to our Facebook page to weigh in on what it means to be a book nerd. Browse digital deals on the NOOK blog, tweet about books with us,or self-publish your latest novella with NOOK Press. And for those of you looking for support for your NOOK, the NOOK Support Forums will still be here.

We will continue to provide you with books that make you turn pages well past midnight, discover new worlds, and reunite with old friends. And we hope that you’ll continue to tell us how you’re doing, what you’re reading, and what books mean to you.

Battery Life

I ran across this article on battery life.  Very detailed.  What I got out of it is don't allow your battery to fully discharge, keep it cool and unplug it when it is charged.

Re: Battery Life

I don't think they said you had to be sure to disconnect when it finished charging.  Here is a quote:

 

"The question is often asked: Should I disconnect my laptop from the power grid when not in use? Under normal circumstances this should not be necessary because once the lithium-ion battery is full, a correctly functioning charger will discontinue the charge and will only engage when the battery voltage drops to a low level. Most users do not remove the AC power, and I like to believe that this practice is safe."

Wrong battery. The NC has a lithium ion polymer battery, not the lithium-ion battery that most laptops have.

It still performs the same.  The only difference is that the electrolyte is held in a polymer instead of an organic solvent. 

 

The charger ceases to charge the battery as the battery reaches capacity. Current won't flow unless it has a path, and that path is essentially open when the battery and charger voltages match.  The NC senses this (the lack of current flow) and changes from saying "Charging" to saying "Full."
