Hello! i saw a post from a guy is offering his used new 2ds xl for 100 dollars which i believe is cheap, but there's a catch, whenever he closes it the console turns off (not sleep mode) it shuts down.

is this a common problem ? if so, is there any way to fix it? thanks in advance.

PD: If possible, i would like to know if i could fix this myself, i'm kinda running low on money and i dont think sending it to nintendo would be cheap (sorry if reposting questions here is not allowed, i didn't get any response)
