A Windows Vista-based computer does not resume from hibernation (S4) or from standby (S3) if you run an application to set an RTC wake-up time

Consider the following scenario:

  • You are running a Windows Vista-based computer that has a Blu-ray optical device and an AMD SB700 reference board installed.
  • You use an application such as Pwrtest.exe or Sleeper.exe to set an RTC wake-up time on the computer.

In this scenario, you cannot resume the computer from hibernation (S4) or from standby (S3). However, if you press any key or the power button, the system resumes correctly.

There is a download that resolves this issue. See Hotfixes for details.
