While connected to a power source, your laptop directly draws power from the A/C adapter rather than relying on the battery; any surplus energy is directed to the battery. Moreover, the battery doesn't experience continuous charging when the laptop is plugged in; it's only recharged when its charge level falls below approximately 95%. Since the battery isn't actively used during this time, it can take several hours for it to naturally deplete that remaining 5% charge without any active power consumption. Hence, using your laptop while it's charging is perfectly fine. However, there are a few considerations to keep in mind: 1. Keeping your laptop battery consistently fully charged can lead to the greatest reduction in its overall capacity (health) over time. This can result in a slightly more significant decline in capacity as time goes on. If you anticipate your laptop being plugged in for an extended duration (such as several months), it's advisable to remove the battery when it's around 50% charged and store it in a cool environment (since heat can also negatively impact battery health). Some manufacturers like Lenovo offer a 'battery health mode,' which achieves a similar effect by adjusting the charging threshold to 50%. 2. When engaging in gaming or resource-intensive activities, ensure proper ventilation for your laptop. This helps prevent the battery temperature from reaching levels that could adversely affect its health.
