Can I remove the battery from the back of my gateway NE71B laptop to reset it? And if so can you tell me how to do it

[Mimi04]

My gateway NE71B laptop is password locked and I dont know password. I've tried every suggestion on Google from pushing f8 to pushing alt and f 8 at the same time. I haven't tried one suggestion about taking the battery out. Does that work and how do I do it
