We designed Surface as a modern standby device
that fine tunes power management dynamically
right down to the individual hardware components.
In the next few minutes we'll explain your two power management options
within modern standby for Windows 10.
Connected standby for always-on computing
and disconnected standby for longer battery life.
We'll also cover your power configuration options within modern standby.
To check the power states available on your device
you can do: powercfg /a
that will show you that connected standby is now available and S3 is not
because it's not necessary.
The main benefit here with connected standby is instant resume
just like your phone you get full PC capabilities immediately.
When you think about low-power states in most PCs
you think about S4, hibernation
or S3, sleep, that still has power to the RAM.
With modern Windows and Surface we wanted to remain connected
while still using less power than traditional sleep and having
much faster resume times.
So compared to S3 connected standby fine-tunes power
management right down to the individual hardware components.
You want your device to be in the lowest power state for as long as possible.
This state is called 'drips'.
From drips, Surface is able to wake up small portions of the system at a time
just enough to handle background tasks such as an incoming email or other
traffic coming across the network.
Other devices such as cameras and sensors are never turned on.
After this, it returns back to drips
Let me demo this for you.
If I press the power button
my device goes into connected standby.
Then if I grab my pen and click the pen button
the device immediately wakes up through bluetooth
and launches OneNote so that I can take notes.
So that is connected standby.
But if you don't need your applications such as email to keep connected to the network
and stay current like in your phone.
You can extend your battery life and still keep instant resume
by opting for a second mode of modern standby.
New with Windows 10 and called 'disconnected standby'.
To do that, we'll just open the PC settings
go to 'System'
'Power & Sleep' and then check these two boxes that say 'stay connected to Wi-Fi while asleep'.
This has disabled Wi-Fi.
So now if I go back and query my power configuration
I'll see that now, disconnected standby is available
and connected standby is no longer available.
Now let's look at the power options.
The first thing I notice, is that I have a lot less power options available
on my Surface devices then on my other devices in my organization.
the reason for that is because Surface intelligently manages the rest of the components
that are not configurable through the UI.
One thing you'll notice is that if you configure through group policies
or if you use power configuration commands
or even registry keys
those will still take effect.
This is not a good thing.
The rule of thumb is if the devices are not configurable through the UI
don't configure them through any other method.
The only setting that we still recommend to configure
and it is available in the UI for Windows 10 but was not for Windows 8.1
is to set the hibernation timeout.
Setting this will tell us after how many minutes of connected or disconnected standby
your device will enter hibernation and stop consuming power.
The Surface image has this configured 2-4 hours
but you may change that value to anything that suits your users.
We hope this explains how power management and modern standby work with Surface
and all the available options.

By for now.
