I have a problem to get my computer into Sleep mode and stay in it. I select Sleep and hit Return or click on Ok and the monitor immediately blanks and the computer around maybe 1 minute and 1/2 later (an Adaptec RAID controller causes a delay) starts to go into Sleep mode just briefly, it sounds like maybe lasting about 1/2 second since the hard drives start to spin down but then start to spin up again. The monitor screen will unblank then and after the RAID controller boots, then I can use the computer. If I then go through the process of putting the computer into Sleep mode again, it will always shut down ok about 1 and 1/2 minutes later. The delay to go to sleep caused by the RAID controller is not the issue, although I would like it to be shorter, it's just that I shouldn't have to try to go through the process of putting the computer to Sleep twice to get it to "stick." I have another computer with the same motherboard, an ASUS Sabertooth 990FX and the same BIOS version. The only significant differences is that it has a different power supply of the same manufacturer (PC Power & Cooling) and a different Adaptec RAID card. The computer I'm having the problem with shuts down normally. I would appreciate some assistance with this problem. Thanks.

Hi, The sleep issue is mostly caused by incorrect driver. You can update the latest RAID card driver, display card driver from manufacture's site. Also, perform clean boot to avoid any third party software confliction. If the issue persists, go to Device Manger, Broadcom Ethernet properties, Power Management, uncheck option for Allow this device to wake the computer. Meanwhile, use the following command to show the device which can wake the computer. powercfg -devicequery wake_armed Best Regards, Niki Please remember to click "Mark as Answer" on the post that helps you, and to click "Unmark as Answer" if a marked post does not actually answer your question.
