MacBook Pro Not Turning On And Not Changing, How to Fix?

My MacBook Pro usually takes a minute or two for the screen to turn on. Yesterday it took 30 minutes to turn on. I decided to finally update the computer because the update has probably been popping up for about a year or so. After that, the screen blacked out and it refuses to turn back on. I was at 100% battery. At first when I would press the power button the keyboard would light up, but now it does not light up at all and the screen is still black. I press the power button and I hear no noise of the computer trying to turn on at all. I waited a couple hours and I pressed the power button frantically. This made my computer say "Voice over on. Username?" in a robotic voice but the computer did not make any noise indicating it was turning on.
