6 FAQs about [What happens if you plug in a power source with a battery ]

Why does my laptop not use battery when plugged in?

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?

What happens if a battery adapter is plugged in?

I found out that when battery is in and then the adapter is plugged, the adapter shuts off (output voltage gradually drops to 0), and the only way to restart it is to unplug it from AC power and plug it in again.

What happens if a battery runs off a power supply?

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.

How does a power supply work?

When you have a power supply, it needs to provide the correct voltage. If there is enough current it will run the computer. If there is more current available then the computer requires to run it will charge the battery with the excess, and if it's not enough, the battery will provide power to top up the difference.
