Fixing Windows 7 sleep problem

Hybrid Sleep is the best thing in 7 that I love most! The Hybrid sleep mode might not work well on older computer, you should check the support level of hybrid sleep mode on your computer with “powercfg -a” command. I will outline some of the common sleep problems in this article, and show you the proper way to diagnose and solve it.

Problem #1 – Sleep mode not supported.
Some older hardware will not support the sleep mode properly, the level of sleep mode supported varies between different hardware. Open command Windows and type “powercfg -a” to list the support level of each hardware.

There are 4 levels of sleep mode:
S1 – Light Sleep
S2 – Deeper Sleep
S3 – Deepest Sleep
S4 – Hibernation

Problem #2 – Unwanted wakes up call.
Many unwanted and unexpected wakes up reported by users. Some wakes up after 2 ~ 3 minutes, some take longer. One principle here: 7 will not automatic wakes itself unless activated the schedule task or hardware. On that basis, we must first determine how many hardware from the computer is supporting wake up function. Open command Windows and type “powercfg -devicequery wake_armed”, this command will list the hardware with wakes up support.

Then go to Device Manager and disable the wake up function on the “Power Options” tab, one by one, to determine the actual hardware that causes such problem. I use this method to discover and disable my mouse’s wakes up feature, from that day, my 7 never wakes up unpredictably.

Finally, you should update your 7, your computer’s BIOS and firmware, then get the latest drivers for your hardware.
