Sleep issues after Windows 7 SP1 installation

Sleep issues after Windows 7 SP1 installation

  • Comments 3
  • Likes

Some customers reported the issues of power management.

Symptom:

Prior to the SP1 installation the system properly went into sleep mode and properly woke up. But, after installing Windows 7 SP1 you may be not able to properly put the system into sleep mode.

You have to press the power button to force the system restart, and it will show an error that the machine was not shut down properly.

Resolution:

Please try the following methods:

1. Install the following hotfix:

A crash memory dump file is not created, or hibernation does not work, when you use a SCSIport miniport driver as the startup device driver in Windows 7 or in Windows Server 2008 R2

2. If the above hotfix didn't resolve the issue, try:

  • Open "Power options" in the control panel.
  • Change the active power plan by clicking the "Change plan settings".
  • Then click "Change the advanced power settings".
  • Scroll down the "Sleep" option and expand it.
  • Change the option "Allow hyprid sleep" to off.
  • Click "OK".

*note*: Someone said the issue was also fixed by switching "Internet Explorer" ->"JavaScript Timer Frequency" to "Maximum Power Savings".

  • I have encountered this problem and the fix for me was the following article/hotfix.

    If you are booting from a device (like an SSD) connected to a fast port (like a SATA 6Gb/s port) that claims to be a SCSI device, this fix is for you.

  • I was having the internal power error BSOD issue on my MSI Big Bang Xpower motherboard when attempting to sleep the system.  Changing the hybrid sleep setting to "off" worked for me and now sleep functions as it should.  

    I am booting Windows 7 64 bit from a SSD attached to the SATA 6Gb port.  My system does read it as a SCSI miniport device.
