AI Customer ServiceIf you are plugged into an uninterruptible power source (UPS), then this is not a concern and removing the battery is fine. If you're on the go and plan to stay plugged in only for an hour or so before you'll need the battery again, keep your battery attached.
If the device is running off battery, the output voltage of the battery will be increased by circuitry to run the device at the required level, however the voltage of the batteries themselves decreases as they loose power (and this is how the amount of charge left is calculated) When you have a power supply, it needs to provide the correct voltage.
The laptop uses ac adaptor when plugged in. Not battery. If you take a look at the battery icon when plugged in, you would see it goes to 100, then gets discharged to some level and charging back again. So the simple answer is that laptop does not use power from battery when plugged in. Battery gets charged and discharged. Does this kill battery?
If you have a removable laptop battery, sometimes removing it while the laptop is attached to an AC outlet can actually optimize your battery life. However, if there's a power outage while the laptop is plugged into an outlet without its battery, there's a risk of data loss.
Also, when left fully charged, the lithium ions, intercalated in the negative electrode, cause it that electrode to slowly expand and lose cohesion. For that reason, laptop manufacturers such as Toshiba, Samsung and Sony have added a power mode that limits battery charge to 50% or 80%, if the laptop is used primarily from the AC mains.
However, if the electricity often disconnects in your home or there's a storm outside that could cause a loss of power, keep the laptop battery attached and avoid the risk of data loss. If you are plugged into an uninterruptible power source (UPS), then this is not a concern and removing the battery is fine.
