Power Button Not Working

Hey,

my laptop is usually in sleep mode and just powers on when I open it up.

So when I hadn’t used it for a week and needed to press the power button… it wasn’t responding

i’m not sure when it stopped working exactly.

But I did let my cousins use it so maybe they knocked it or something…

however the power button definitely worked before.

anyway, I tried taking the back off and checking all the cables and connected firmly.

i even unplugged the battery and plugged power in. It turned on right away and all of the keys worked except the power button.

I’m really unsure what to do.

Any idea?
