# Why does my computer turn off when I close the lid?

When you close the lid of your laptop, your computer will suspend in order to save power. This means that the computer isn't actually turned off - it has just gone to sleep. You can resume it by opening the lid. If it doesn't resume, try clicking the mouse or pressing a key. If that still doesn't work, press the power button.

Some computers are unable to suspend properly, normally because their hardware isn't completely supported by the operating system (for example, the Linux drivers are incomplete). In this case, you may find that you are unable to resume your computer after you've closed the lid. You can try to fix the problem with suspend, or you can prevent the computer from trying to suspend when you close the lid.

## Stop the computer from suspending when the lid is closed

If you don't want the computer to suspend when you close the lid, you can change the settings for that behavior:

Be very careful if you change this setting. Some laptops can overheat if they are left running with the lid closed, especially if they are in a confined place like a backpack.

1. Fare clic sull'icona a destra nella barra dei menù e selezionare Impostazioni di sistema.

2. In the Hardware section, click Power.

3. Set the drop-down menus next to When the lid is closed to Do nothing.
