Slightly OT:
“The question is often asked, should the laptop be disconnected from the
main when not in use? Under normal circumstances, it should not matter with
lithium-ion. Once the battery is fully charged, no further charge is applied.
However, there is always the concern is malfunction of the AC adapter, the
laptop or the battery.”

I have owned laptops since the early '90's and have not experienced battery
failure or significant short-lived battery life due to leaving the battery in
the laptop while plugged-in. As long as the battery is used once in awhile
and recharged about once a month, the user should not worry about the battery
being seriously harmed during times when laptop is plugged-in. In the design
of laptop battery, there are current and voltage limiters that do not allow
the battery to be cooked. Heat is the main enemy of lithium-ion batteries.
Heat usually from being stored in high temperature areas or being used under
high temperature conditions such as non-air conditioned or poor air flow
environments. I have found that leaving the battery in my laptop is far
better than taking it out in a hotel room and then accidentally leaving it
behind.
The myth of significantly damaging the laptop battery by having the laptop
plugged-in is perpetuated by Websites who cut and paste from each other. I
have yet to find technical data to back-up the claims that these websites
(usually sellers of laptops batteries) make.
