How Does the Battery Supply Notebooks and Laptops with Electricity?

Hello everyone,

I have been drawing up plans for a custom notebook that I am going to build (it is going
to have a custom case) after having built multiple desktops. I have planned out everything
except for how the battery that I am currently going to use supplies electricity to the
motherboard and other components.

So my question comes down to this:
How/what hardware component is used to supply the electricity to the rest of the notebook
and if it is normally included in the shell/case of the notebook, is there any way for
me to put this piece in independently (if this is the case, what would the hardware be
for the Panasonic CF-VZSU1431U battery?). Or if I'm completely wrong with all of this,
how does the battery supply power in general?

Thank you in advance.

 

If I recall right there are DIY laptops out there already to build.

 

It supplies power in the exact same way that the external power adapter does. Voltage regulator software on the motherboard turns the ~19v from the power adapter and ~12 volts from the battery into the different voltages that the components need to operate.

 

Okay, so its just another adapter that is on the motherboard correct?

 

Sorry, I meant to say hardware and not software. Yes, it is as if there is a different power supply on the motherboard that works on both AC adapter and battery voltages.

 

Okay, thanks!
