| description | A device suspend method and a computing device are provided. In the method, before a device enters a suspend state, memory space occupied by a background process that is unrelated to a foreground process is released. In this way, the background process that is unrelated to the foreground process is not saved in a memory of the device. In other words, data stored in the memory when the device is suspended is reduced. Therefore, when the device needs to be woken up, only a relatively small amount of data needs to be read from the memory, and a working state can be rapidly restored. This can reduce a delay of reading data from the memory when the device is woken up, thereby accelerating a wakeup speed of the device. In addition, the data is stored in the memory when the device is suspended. Therefore, in the suspend state, power needs to be supplied only to the memory of the device, thereby ensuring low power consumption of the device. |
