Hi! So basically my parents took my phone away, so now I don't have an alarm. I am not willing to buy a cheap horrible alarm clock, so I found a website that can also wake me up just like an alarm. The problem is I have to keep my computer on for eight hours during the night, because if I turn my computer off, the alarm won't work, unlike a phone, which you can turn off during the night and still have the alarm wake you up. So my question is, is keeping my computer on for eight hours during the night dangerous? Not only to it exploding, just in general, like will it work worse, or start a fire, or crash, or something else? Thanks! I have a lenovo thinkpad t420 if that helps!
