[Aspire 5] Laptop won't turn on by clicking the power button

So like the title says, my Laptop (Aspire 5) doesn't turn on by clicking the power button. But when I click any other key it turns on but if I release that key, the laptop turns off. Laptop bought at the end of July.
What should I do?

If it is that new, I would contact the manufacturer as it should still be under warranty.
