Q: Does it harm a laptop to keep it plugged in all the time?

A: It is not harmful to keep a laptop plugged in all the time, but the laptop’s battery will inevitably die. By keeping the laptop on wall power with the battery in, the battery will eventually lose its ability to keep a charge. You should unplug the laptop and use it on battery power regularly. You should use the battery until it is almost completely depleted then plug it back in to charge at least once or twice a week.
