Matt,
Providing you have the correct adaptor, you can successfully run the Laptop off the Car battery and change the Laptop battery at the same time.
There are two methods of doing this.
You can connect an inverter to the vehicle's 12 volt supply and then the Laptop to the inverter via the standard Laptop's power adaptor. The only concern here is that some Laptop require a pure sine wave inverter which are more expensive than the cheaper modified sine wave
inverters. The Inverter provides 240 volt AC output from 12 volt DC input.
Or, you can connect the Laptop to the vehicles 12 volt supply via a 12 volt adaptor that provides a higher DC voltage output to suit the particular Laptops requirement. The Kerio brand is an excellent compact adaptor that does away with the need for a "cumbersome" inverter and separate adaptor. The "negative" here is that the Kerio adaptor must be suitable for the particular Laptop you are using and the Kerio output voltage can be adjusted by means of a fuse like linkage device.
Some Laptops, like my Dell Inspiron 6000, will run OK off the Kerio (with the right 12 volt adaptor plug, but will not charge the Laptop's internal battery due to a unique "Dell design". Dell do however provide an accessory adaptor that replaces the original one and can be plugged into 240 volt AC, 12 volt DC vehicle supply, or even an Aeroplane socket, simply by changing the input lead.
Any of the above options will provide suitable power to your Laptop and at the same time , ensure that the internal battery is fully charged when you choose to run it away from the vehicle.
