I have an asus laptop running Windows 7. Last night, I hit a key accidentally and it switched into something called quiet office mode. I've looked around and can't find a way to switch it back, I've tried hitting all the keys in the area I think I accidentally hit to turn it on, and I've searched around for a solution both on the computer's help guide and the internet but I couldn't find anything. Please don't bother responding to say "hit the key again" since I'm not sure which key made it happen. Thank you so much.
