Various voltages in laptop power sources?
On the back of my Dell Latitude CPi-A366XT's 4460 MaH battery pack, it says the battery voltage is 14.8 volts.
On the plug-in (to the wall outlet) power supply, it says its output is 20 volts DC.
Do laptops have some internal circuitry that allows them to regulate the power they get from various sources to 12 volts and 5 volts and whatever else the computer needs?
What I'd like to know is if I could hook up the stock battery pack, the plug-in power supply, a 12 volt DC CAR BATTERY, or a 16 volt DC racing car battery, or any conglomeration of DC power sources that totalled up to the 12-20 VDC range and the laptop would run equally well on all?
What about an adapter that would plug into a car cigarette lighter and power the laptop with the car off or running (changes the amount of volts somewhat)?
It's not like I plan to do this every day, but I'd like to know for those "just in case" situations.
