Claims:1. A machine-readable storage media having machine-readable instructions stored thereon, that when executed, cause one or more machines to perform a method comprising:
detecting, during transition from a wake event to an operational state of a computing device, that a password for an endpoint device is stored in a secure memory of a first device;
fetching the password for the endpoint device from the secure memory of the first device; and
unlocking the endpoint device with the password for the endpoint device fetched from the secure memory.
, Description:BACKGROUND
[0001] The Modern Standby (formally Connected Standby) standard by Microsoft® is a specification for Window® 8 and later operating systems and platforms that enables an instant on/off user experience. Modern Standby allows systems and devices to enter low power states while remaining connected to a network. When a computer system enters a Modern Standby state, components and devices of the system are placed in an intermediate or low power state. An endpoint device, such as a memory device, may be placed in one of two low power states: D3hot (auxiliary power provided) or D3cold (no power provided) as defined by device power state of the Advanced Configuration and Power Interface (ACPI) specification.
[0002] Generally, a password is submitted to a password-protected endpoint device before the computer system completely boots up to unlock the device. If the endpoint device subsequently enters D3hot, it will remain unlocked. However, if the endpoint device subsequently enters D3cold, it will revert to a locked state.

DETAILED DESCRIPTION
[0008] Some embodiments describe techniques for restoring a password-protected endpoint device (e.g., a memory device) associated with a computer system to an operational state from a low power state. In some embodiments, a password-protected endpoint device locks when it is in a low power state. A password for the password-protected endpoint device is received from a user when the computer system boots up. The boot process uses the password to unlock the endpoint device, placing it in an operational state. The boot process also stores the password in a secure memory (e.g., serial peripheral interface (SPI) flash device). Subsequent to being unlocked (e.g., during the boot process), the endpoint device enters a low power state that causes the endpoint device to enter the locked state. In some embodiments, when power to the endpoint device is restored, the password is fetched from the secure memory and used to unlock the endpoint device, thereby restoring the endpoint device to an operational state without user input of the endpoint device password.
