laptop won’t turn on

hi. i have a dell laptop (latitude 5591, got it in 2018) and i was playing minecraft when it just turned off. i’ve been having trouble with it for the past year or so and am going to get a new one soon, but really need to get some files off of it. does anyone know what i might be able to do? i would prefer to not bring this to someone else to fix and have been learning about how computers work, but if this seems like something i should bring to someone, i will.

previous troubles include freezing screen, screen stopping and making some static-ish sound, being really hot, lagging constantly, keys not always working, more i can’t remember.
