You should always go to the owners manual first, as there are a number
of different battery types and what works well for one type may not for
another. If your laptop uses lithium-ion or lithium polymer batteries,
no cycling or complete discharge is necessary. Some modern batteries
can become permanently damaged through a complete discharge, typically
through polarity reversal. Most batteries of this type have built-in
protection to keep them from being completely discharged, but I suspect
this might not help if an already discharged battery is then left in a
closet for a couple of months over summer vacation in a school setting.
It's probably a good idea to completely charge all batteries before
storing them away for long periods of time. Again, Read The Fine

Subject: laptop battery cycling
What do people do about maintaining laptop batteries?
The advice I've been given is to completely discharge them once a month
First - does this advice agree with your opinion/experience?
Second - if you do this, how do you go about it, and keep from having
the laptop go into "sleep" mode?
Thanks in advance for suggestions.
