Laptop not turning on, caps lock blinking.

[tropicalia]

My sibling's laptop has failed to boot suddenly, now it goes to a black screen and the caps lock indicator blinks. It blinks 3 times with a long pause between each, as well as 2 times with a short pause. I saw a document explaining that reseating the memory is a fix for this issue, but I don't feel like taking the entire laptop apart unless unavoidable. Any alternative options you might recommend?
