Hybrid sleep is a combination between sleep and hibernation, allowing your computer to write out all its RAM to the hard drive, and then go into a low power state that keeps RAM refreshed. This state allows users to quickly resume their computers from sleep, and also restore them from hibernation in case there’s a power failure.
It appears that the Anniversary Update doesn’t get along well with the hybrid sleep state, as many users are reporting this feature is missing altogether from the power option list.
Hybrid sleep is missing in the Anniversary Update
Can anybody explain why and how to get it back?
I go to power options –> advanced settings and under sleep I only get Hibernate after where as before update I got Hybrid sleep option as well. Before Anniversary Update I got the above. I now only see Hibernate after.
It is worth mentioning that certain motherboards and BIOS systems don’t support the hybrid sleep feature. To see that power states your computer supports, run the command powercfg –availablesleepstates in Command Prompt.
Hybrid sleep is missing – how to fix this
Solution 1 – Restore the default settings in the power plan
Sometimes, a personalized power plan may disable a series of features. To enable the default power plan, follow these steps:
- Go to Control PanelHardware and SoundPower Options
2. Check the Balanced plan > select Change plan settings > Restore default settings for this plan.
Solution 2 – Update your drivers
Make sure both your hardware and software drivers are updated – you can use Windows Update. If there are any new drivers available, install them, restart your computer and then check to see if the hybrid sleep option is available.
All your drivers need to be updated, but doing it manually might be annoying, so we recommend you to use a dedicated third-party tool (100% safe and tested by us) to do it automatically.
Some of the most common Windows errors and bugs are a result of old or incompatible drivers.
