What happens if I use a weaker power supply?

What happens if I use a weaker AC adapter when charging a laptop, does it break or nothing happens?

Does not happen, does not load at all or only slowly

If the tension is too strong, something can break. Respectively. Break a fuse if one is installed.

But I think it will not load then. The battery needs a certain voltage. I would not do it. Not that the battery later saves no energy.

Maybe you are lucky that a technician is online and you answered the question.

What happens if I remove the battery?

With me the laptop loads

I think he would load only slowly. But in the long run it could affect the battery.

Have the but removed before or not connected

Hi

if you use a weaker power supply, it may be that the components of your PC are not sufficiently supplied with power and thus can't perform their full power or not even start.

(Tower PCs) It is always advisable to buy a power supply with a higher wattzahl in order to supply all components safely with enough power.

So with the values like ampere or volt, it is a little bit weaker, but has the same amount of watts (45), does that make a difference?

So the volt that's the tension and this should definitely fit the must not be excessive.

The wattzahl is not so important, if this is lower then the battery just slows down. But if the voltage is higher then you realize that the battery is hot and if a battery is hot then that can't be healthy. With hot is meant not so 30 ° but already 40 to 60 degrees Celsius.

Edit: When the voltage is low, the battery loses voltage and eventually it will give up the ghost and you will not be able to charge it anymore
