Cannot connect Samsung PC to internet

Due to the limited space on a laptop keyboard, many keys will serve multiple functions. If they don't appear to be working correctly it's likely due to the alternate purposes of the keys being used instead. It's also important to have the language of your keyboard set correctly. Here are a few common issues and their solutions.

If you have a backlit keyboard, it can be toggled on and off with the Fn and F9 keys. If the key combination does not work, you may need to install the appropriate Samsung Settings app on your PC. If the key combination does something else (like turn the screen on and off), this means your model does not have a backlit keyboard.

If a key has come off your keyboard you can easily replace the key yourself without any special tools, as long as all the pieces are available and undamaged.

Pressing the Fn key turns the Function Keys into hotkeys (or shortcuts) for a number of system functions. For instance, Fn + F2 will darken your screen and Fn + F3 will brighten it. If the keys are not responding as expected, it can be easily fixed by adjusting the settings or checking for available updates.

Many external monitors and tablet PCs can be rotated to better suit your workspace, but if you rotate it by accident, you can quickly revert it to your preference.
