If your Chromebook is on but you cannot access the internet, you might have turned off the Wi-Fi functionality. In order to turn this back on, click your account photo, click "No Network" and then finally click the Wi-Fi on/off switch. If you see "Connected to" and your Wi-Fi name, your Chromebook is already connected to the Wi-Fi.

After turning on my Chromebook, I cannot see anything, or the images are too dim for me to see well.
