AI Technical Summary

Problems solved by technology

[0006] Suspend mode also has undesired limitations
Although significantly faster than hibernation, suspend mode uses more power because volatile system memory remains powered
Also, if the computing device loses power while it is suspended, memory data may not be recoverable and any information not saved to the hard disk will most likely be lost
This can happen easily, such as when a user unplugs a computing device or when a power failure occurs

Embodiment Construction

[0017] As described in the "Background" above, conventional methods of implementing hibernate and suspend modes have undesired limitations. Hibernation is slow and can damage the hard drive. Suspend mode uses more power and memory data may not be preserved during a power failure. This disclosure describes techniques for storing memory data during hibernation or suspend using non-volatile memory devices, such as flash memory. By doing this, the hard drive and / or data are more secure and can use less power.

[0018] In the following discussion, an example operating environment is described. Additionally, example methods are described that may be employed in the example operating environment, as well as other environments. In the following discussion, reference will be made to this environment by way of example only, and thus, the implementations described below are not limited to the example environment.

Description

[0001] related application [0002] This application claims priority to US Provisional Patent Application Serial No. 61 / 142,502, filed January 5, 2009, the entire disclosure of which is hereby incorporated by reference. This application also claims priority to US Provisional Patent Application Serial No. 61 / 142,699, filed January 6, 2009, the entire disclosure of which is hereby incorporated by reference. This application also claims priority to US Provisional Patent Application Serial No. 61 / 143,548, filed January 9, 2009, the entire disclosure of which is hereby incorporated by reference. Background technique [0003] Modern computing devices employ power-saving modes when not in use. Hibernation is a mode in which the operating system (OS) saves memory data in the form of a hibernation file from volatile system memory to the OS boot partition of the hard drive, after which the computing device shuts down. When turned back on, the basic input output system (BIOS) of the c...
