Symptoms
Assume that you have a computer that uses the StorAHCI driver on non-hybrid Serial Advanced Technology Attachment (SATA) hard disks. The operating system is in one of the following builds or a later build:
- 9870.0.14022-1912 fbl_release
- 9870.0.141022-1846 winmain
In this situation, the computer cannot start or it cannot be resumed from sleep.
Cause
This problem occurs because the StorAHCI driver enables the Power-Up in Standby (PUIS) feature for non-hybrid SATA disks. However, the BIOS does not send a spin-up command to restore disk settings or to start from the hard disks.
Resolution
This compatibility update is offered when you upgrade to Windows 10 Technical Preview or Windows Server Technical Preview.
Note After you apply this update, StorAHCI driver does not enable the PUIS feature for non-hybrid SATA disks.
Status
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

About PUISPUIS is a specific hard disk drive (HDD) feature that enables the drive to spin up only when it is required by a command, instead of when the computer is turned on. This feature helps save energy and enables staggered spin-up times for multiple hard disk drives.
