First it’s important to understand what overcharging is:
Over-charging occurs when the charger keeps the battery at a temperature that is warm to touch (body temperature) while in ready condition.
Li-Ion laptop batteries have built-in controller chips which prevent it from overcharging, as they can explode if overcharged. Overcharging does not affect the life span other than potentially destroying the battery.
A lithium-based battery should never be allowed to get warm in a charger. If you have this happen, the battery is no good or the charger is not working properly. Don’t continue to use the battery or charger if this happens.
A Lithium-ion battery may be damaged by extensive overcharging (continuously on a charger for more than 24 hours). Damage to the battery from overcharging would only occur in the very unlikely event of a malfunction of the charging system.

uhhhhhhhhhhhh huh........ do you want a medal?
my G7 and phones have Li-Ion batteries and i leave them on charge at home - no issues because they stop charging when there 'full' same as laptops etc
Well, in my experience with laptops and other rechargable stuff, leaving them plugged in all the time does seem to shorten the battery life (not a very scientific statement, I know). Li-polymer stuff doesn't like to be fully discharged either.
what is Overcharge? The forcing of current through a cell after all the active material has been converted to the charged state, that is, continued charging after reaching 100 percent state-of-charge.

well, every laptop battery should work in a reasonable temperature, when you over charge it, the temperature is ascend at the same time, if it is hot enough, the PCM pannal may be destroy and self-ignite may happen.most over charge will improve the decline of the laptop battery. i have a battery for toshiba satellite A65 and i often over charge it before, and the capacity decreased to 70% of standard.for my over charge it over 1 month,i stop this stupid method by a friend's suggestion that "not only charge when your toshiba satellite A65 battery is 100% empty! it may be more and more hungry!" so charge your laptop battery when it is near to empty.
