# 为什么我合上笔记本盖时它会关闭？

当您合上笔记本盖，计算机将会挂起以省电。也就是说计算机并没有真正关闭——它只是进入睡眠，您可以打开盖唤醒它。如果翻盖后不能唤醒，试着点几下鼠标，或者按一下键盘。如果还不能工作，那么就按电源按钮。

一些计算机不能很好地挂起，这通常是因为硬件不完全支持操作系统(例如，Linux 驱动不完善)。在这种情况下，您可能会发现合上盖再打开时，不能唤醒电脑。您可以试着修复挂起错误，或者您可以阻止电脑在合上盖时挂起。

# Stop the computer from suspending when the lid is closed

These instructions will only work if you are using systemd. Contact your distribution for more information.

You need to have the Tweak Tool installed on your computer to change this setting.

Install Tweak Tool

If you do not want the computer to suspend when you close the lid, you can change the setting 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.

Open the Activities overview and start typing Tweak Tool.

Click Tweak Tool to open the application.

Click the Power tab.

Switch Don't suspend on lid close to ON.

Close the Tweak Tool window.
