Using a laptop while plugged in does not ruin the battery, especially if it has a modern lithium-ion battery. However, prolonged overcharging can lead to slight wear. To optimize battery health, try discharging it to around 20-30% before plugging it back in and avoid extreme temperatures. Most laptops have smart chargers, so leaving it plugged in occasionally won't be harmful.
