razer blade 15 advanced battery removal

I got this computer 3 years ago, the warranty is up on it and i don't want to pay razer to replace the battery as i'd rather buy a different computer after the many issues i've had with it. i just wanted to know what would be the best way to remove it myself, what kind of screwdriver it needs, etc. so it doesn't ruin the rest of the computer so i can put my stuff on an external hard drive without the risk of a fire. i just want to get it out of here as quick as possible without sending my computer anywhere
