How to Enable or Disable Hibernate on the Surface Pro X

I am sure you have seen that I am the proud owner of a Surface Pro X. The Surface Pro X is one of the latest Microsoft Surface devices, and instead of coming with an Intel or AMD x86 processor, it comes with a custom Qualcomm ARM CPU, called the Microsoft SQ1. The Surface Surface Pro X also runs Windows 10 on ARM, which allows you to run ARM64 and emulated x86 (32-bit) apps. Since I really like this device and the always-on feature, I just quickly want to share how you can enable or disable hibernate on the Surface Pro X.

The reason why I want to disable hibernate is that I can take advantage of the always-on capabilities for a much longer period of time. To understand the differences between shut down, sleep, or hibernate, you can check out the following Microsoft support article.

Shut down, sleep, or hibernate your PC and the Surface Pro X

There are different ways of handling your PC when you are not using it, you can turn your PC off completely by shutting it down, make it sleep, or you can hibernate your PC.

Sleep

Sleep uses very little power, your PC starts up faster, and you’re instantly back to where you left off. You don’t have to worry that you’ll lose your work because of your battery draining, because Windows automatically saves all your work and turns off the PC if the battery is too low. Use sleep when you’re going to be away from your PC for just a little while—like when you’re taking a coffee break.

Hibernate

This option was designed for laptops and might not be available for all PCs. Hibernate uses less power than sleep and when you start up the PC again, you’re back to where you left off (though not as fast as sleep). Use hibernation when you know that you won’t use your laptop or tablet for an extended period and won’t have an opportunity to charge the battery during that time. First check to see if this option is available on your PC and if it is, turn it on.

Enable or Disable Hibernate on the Surface Pro X

To enable or disable hibernate you can use the following options by using PowerShell or the Command Prompt as administrator.

Disable Hibernate run:

powercfg.exe /hibernate off

Enable Hibernate run:

powercfg.exe /hibernate on

You can also find out more about the battery behavior of your Windows 10 devices by using powercfg, so you can see how much battery power your devices uses in sleep or hibernation or while using it. I wrote a blog post called Troubleshoot Windows 10 Battery Life and Modern Standby.

I hope this post helps a couple of people dealing with the power management of Windows 10 and how to enable or disable hibernate on the Surface Pro X. If you have any questions, feel free to leave a comment.

Troubleshoot Windows 10 Battery Life and Modern Standby

More and more mobile devices are out there, and Windows 10 has some need features like Modern Standby, formerly known as InstantGo or Connected Standby. Modern Standby provides an instant on/instant off user experience that users expect to have with their phones. Devices like the Surface Pro, Surface Go, and Surface Book 2 are using Modern Standby. Now that said there are always scenarios where battery life or standby doesn’t work as we wish. This blog post should help to troubleshoot Windows 10 battery life and modern standby on Windows 10, using inbox tools. For example, “powercfg”, which allows you to create Windows 10 battery reports.

Check hardware support for standby modes

Powercfg information

First of all, you can check with power states, standby modes, or the available sleep states supported by your hardware using the following command:

powercfg /a

General Windows 10 Battery life and standby issues

In some case, you can run in some issues where you have your battery draining more than expected during the Modern Standby time. This could be of the following reasons:

  • Drivers – Make sure you have the latest drivers installed
  • Firmware – Make sure you have the latest Firmware (BIOS) installed
  • Mails –  The Windows communication app keeps the broker infrastructure (BI) system active. BI, in turn, keeps the WLAN network up so that the system stays up-to-date with emails. If you get a lot of emails, this can end up in a higher power drain.
  • Software –  Some installed legacy Software which does not let you go into the InstantGo modus.
  • VPN Clients – Some older VPN Clients can also cause issues with InstantGo
  • Network Activity – The WLAN device might have a challenging radio environment, and the Windows system might not be able to establish a reliable Internet connection. We see how these events affect the WLAN device, which, in turn, impacts the battery.


InstantGo powercfg

Troubleshoot Windows InstantGo (Connected Standby)

In Windows 8 Microsoft released a feature called InstantGo (formerly know as Connected Standby) which should bring smartphone like Power Management features to your Windows tablet or notebook. Devices such as the Surface Pro 3 do offer this feature. This post should help you troubleshoot issues with InstantGo or Connected Standby.

InstantGo requires the following:

  • Windows 8.1 Operating System (In Windows 8 this is called Connected Standby)
  • A firmware flag indicating support for the standard
  • The boot volume must run on a SSD disk
  • Support for NDIS 6.30 by all network devices
  • Passive cooling on standby
  • Secure Boot
  • Memory to be soldered to the motherboard
  • The Hyper-V Hypervisor role must be disabled on Windows 8 and Windows 8.1 systems. Windows 10 Hyper-V will allow you to use Hyper-V and InstantGo at the same time.

Check if the hardware supports InstantGo

To check if your hardware supports InstantGo you can run the following command:

 
powercfg /a

InstantGo powercfg

InstantGo Issues / Connected Standby Issues

In some case you can run in some issues where you have your battery draining more than expected during the InstantGo or Connected Standby time. This could be of the following reasons:

  • Drivers – Make sure you have the latest drivers installed
  • Firmware – Make sure you have the latest Firmware (BIOS) installed
  • Mails –  The Windows communication app keeps the broker infrastructure (BI) system active. BI, in turn, keeps the WLAN network up so that the system stays up-to-date with emails. If you get a lot of emails this can end up in a higher power drain.
  • Software –  Some installed legacy Software which does not let you go into the InstantGo modus.
  • VPN Clients – Some older VPN Clients can also cause issues with InstantGo
  • Network Activity – The WLAN device might have a challenging radio environment and the Windows system might not be able to establish a reliable Internet connection. We see how these events affect the WLAN device, which, in turn, impacts the battery.
  • Hyper-V – If you run Hyper-V in Windows 8 or Windows 8.1 you can not run InstantGo, this is solved in Windows 10.

Troubleshooting InstantGo / Troubleshooting Connected Standby

To get some more information about your device and InstantGo or Connected Standby you can use the following tools and reports.

powercfg /SleepStudy

Powercfg SleepStudy

The maybe best way to Troubleshoot Connected Standby or InstantGo issues, is to use the powercfg /SleepStudy command. This will generate a Sleep Study report which allows you to analyze different things about Conncted Standby:

Connected Standby / InstantGo Overview

SleepStudy Report

Connected Standby Transitions

SleepStudy Report Connected Standby Transitions

Connected Standby Sessions

Here you can analyze which application or driver did use battery resources during the Connected Standby session.

SleepStudy Report InstantGo

powercfg /batteryreport

powercfg batteryreport

With powercfg /batteryreport you can generate a report about how your battery is used.

Battery Report

And you can also see what kind of state drained your battery, if this was an active session or a Connected Standby session.

Battery Report Battery Usage

powercfg /energy

PowerCFG Engery

With powercfg /engery you can see not only InstantGo or Connected Standby issues, you can see what other applications, drivers and more does could drain your battery.

Energy Report

I hope this helps you to troubleshoot Connected Standby issues.
