Should laptops remain plugged in when their battery is 100% charged?
Is there any problem if I left the charger connected to the laptop after full charging? And if there is, How can I deal with that to not harm the battery?

Yeah, there are at least a couple of duplicates, but no single one addresses all the issues, that I can see. – Daniel R Hicks Oct 04 '12 at 20:06

Minor gripe: When a thread is closed for being a "dupe" they say that some answers should be moved from the dupe to the "original". But I've never seen that happen. – Daniel R Hicks Oct 04 '12 at 20:18

Laptop chargers pretty much universally turn off (or go into low "trickle" mode) when the battery is fully charged.
There is a problem, however, that your typical Li-ion laptop battery "doesn't like" being fully charged -- the overall battery life (not the "life" of a single charge) will be extended if only charged to 60-80%. Some laptops have a setting to enable this lower-level charge (for those that hardly ever use the laptop on battery only), but many unfortunately do not.

Usually the battery stop charging after completion. So normally you can leave it. Actually, I think the charge/discharge process is what decrease the batteries performance.
You have more info here
