The system does not enter Connected Standby after you install update 2996799 in Windows

Applies to: Windows Server 2012 R2 DatacenterWindows Server 2012 R2 StandardWindows Server 2012 R2 Essentials


Consider the following scenario:
  • You have update 2996799 installed on an Intel® Atom™ Processor Z373x series based computer that is running Windows 8.1, Windows RT 8.1, or Windows Server 2012 R2.
  • You plug an SD card in to the computer.
  • You hibernate and then resume the computer.
In this scenario, the computer cannot enter the Connected Standby power state after the computer resumes from at least one hibernate cycle.


This issue occurs because update 2996799 does not handle certain power I/O request packets (IRPs) correctly.


To resolve this problem, we have released an update for Windows 8.1, Windows RT 8.1, or Windows Server 2012 R2. Before you install this update, check out the prerequisites.
