you have to reset the computer.
It depends why it's changing. Windows default settings dims the display if you run a laptop off just the internal battery (to conserve power). You can change the settings, but you'll shorten your battery's working time between charges.
Not necessary. No problems will be encountered when changing the battery.
You disconnect the power and ground and take the old battery out n put in a new one.
On a laptop with battery power it will work.
