Hey carolina,
Do you still need some laptop advice or have you bought one yet?
Remember, to keep your laptops battery working efficiently all the time the same logic applies to a phone, if you keep something charged 8 hours a day, it will destroy the battery due to overcharging. It's why phone batteries go bad because of overcharging.
My advice plug your laptop in fully let it charge and play your games, when the laptop comes down to 10/20% whatever it notifies you at, plug it in to charge and once its full remove the cable, this prevents overcharging and longevity with the laptop battery.
Just some advice hope it helps.
