It will disable the (for some) broken feature, which can kick in when leaving your device alone for some minutes (it will then go to sleep) which can lead to the "unable to wake" problem.
As far as I can see there were 3 types of problems:
- Black screen (but working camera), when trying to recover from sleep. This one is fixed in the newer display driver. Workarounds were: WindowsKey + P or CTRL + ALT + DEL
- Connected Standby which is draining your device due to software (or a driver), like your mouse which is keeping your PC from getting into deep sleep. If your device is able to wake from sleep, you could try and locate the drain using: powercfg /sleepstudy.
- Connected Standby + deep sleep, which is putting your device into a deeper sleep, before the 2/17 update this didn't happen, therefore people are experiencing problems with it now. Your device is unable to turn itself completely on, and the only thing
working is the backlight of your keyboard.
When you only suffer from issue 2: Lucky you, your sleep/wake states are working, but a device/driver/hardware or software is draining your battery (just like some apps on your phone can drain your battery), I do think this is software installed by yourself
(might even be skype or another chat tool). What you can try is putting off the option "Stay connected to WiFi when in sleep" (or something like that)
When you suffer from 3 (maybe in combination with 2): Well you have to wait for Microsoft to provide a fix for it. Note: You might be suffering from issue 3, but since your device isn't going to the deeper sleep (due to issue 2), you might not suffer from
it (but it drains your battery down).
For time-being, I've disabled the connected standby completely, I don't mind waiting for a couple of seconds to boot up (from hibernate). At least it isn't draining my battery.
And there is ofcourse, the people who don't suffer from issue 2 and 3. I wanted to be you!
