Battery

A device suspension method and a computing device are provided. In the method, before a device enters a suspended state, memory space occupied by a background process that is unrelated to a foreground process is released. In this way, the background process unrelated to the foreground process is not saved in a memory of the device. In other words, it reduces data stored in the memory when the device is suspended. 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.

A file management method, a distributed storage system, and a management node are disclosed. In the distributed storage system, after receiving a file creation request sent by a host for requesting to create a file in a distributed storage system, a management node allocates, to the file, first virtual space from global virtual address space of the distributed storage system, where local virtual address space of each storage node in the distributed storage system is corresponding to a part of the global virtual address space. Then, the management node records metadata of the file, where the metadata of the file includes information about the first virtual space, and the information about the first virtual space is used to point to local virtual address space of a storage node that is used to store the file. Further, the management node sends, the information about the first virtual space to the host.

An electronic device includes a processor, a volatile memory, and a non-volatile memory. The non-volatile memory stores a first operating system, and the electronic device works in a first working mode and a second working mode. When the electronic device is in the first working mode, a second operating system is run in the volatile memory. When the processor detects that the electronic device reaches a preset condition for entering the second working mode, the non-volatile memory is enabled, and non-system data in the volatile memory is moved to the non-volatile memory. The non-system data does not include the second operating system. After the movement of the non-system data is completed, the volatile memory is disabled, and the first operating system is run in the non-volatile memory, so that the electronic device enters the second working mode.
