    Probably doesn't matter these days. You don't say what laptop you have but assuming it is fairly new (last decade) then I'd not worry about it.

    It probably isn't charging all the time anyway - mine runs down to 95% and then recharges to 100% and I haven't unplugged it for several years. Hover your cursor and have a look:

    @jamos316, It's quite safe to leave it plugged in, charging will turn off when the battery is full. Li-ion batteries do wear out with use. General rule of thumb - don't let it fully discharge before charging the battery, a deep discharge then a full charge puts more strain on the battery than lots of little top-ups.

    Similar to a mechanical device that wears out faster with heavy use, the depth of discharge (DoD) determines the cycle count of the battery. The smaller the discharge (low DoD), the longer the battery will last. If at all possible, avoid full discharges and charge the battery more often between uses. Partial discharge on Li-ion is fine. There is no memory and the battery does not need periodic full discharge cycles to prolong life...

    ...The question is asked, “Should I disconnect my laptop from the power grid when not in use?” Under normal circumstances this should not be necessary because charging stops when the Li-ion battery is full. A topping charge is only applied when the battery voltage drops to a certain level. Most users do not remove the AC power, and this practice is safe...
