What should you do if you poked yourself fairly hard in the eye with the corner of your laptop and it's a bit red and is it serious?
It should be fine. If your eye seems to keep getting redder then check with your doctor, you could have internal bleeding or a fractured eye, which can cause blindness or scars. It's best to go see a Optometrist and tell him/her what you did. No need to go through your doctor for this. Any bump to the eye area or eyeball itself is extremely important. Sight is everything!
Be smarter than the microphone. You click on the microphone button at the top left corner and it should be on. But it depends if you are using a laptop or desktop computer. If you are using a desktop computer there is no microphone. But if using a laptop, click on the microphone button on the top left corner. Then the microphone should turn on.
Don't ask other people what makes for the best laptop in the world, ask yourself what makes for the best laptop in the world. Imagine you sit down at the best laptop in the world: What's the first thing that you do? Whatever it is, that's what you need to be looking for; a laptop that can do that better than any other laptop ever created. Follow that to the right laptop for you.
