My laptop keeps turning off when using. It's about 5 years old. Lenovo, no battery. Just had it formatted. After I had it formatted, it started turning off. But it doesn't turn off when I let it play music and just let it play, I don't touch it. What could be the reason why it keeps shutting down on its own? and it doesn't shut down properly. I really need some help about this. Thank you.
