Recentemente, substituí meu disco rígido por um SSD da Sandisk e fiz uma nova instalação do Fedora 21 (anteriormente usando o F20). Agora meu laptop não liga, e não sei qual dos dois está causando o problema. Se eu colocá-lo para dormir, a tela ficará em branco, mas a energia permanecerá ligada. Se eu desligar, ele trava no logotipo do Fedora. Reinicialização funciona no entanto. (Provavelmente) saída relevante do dmesg:
