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:
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.
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
Connected Standby Transitions
Connected Standby Sessions
Here you can analyze which application or driver did use battery resources during the Connected Standby session.
With powercfg /batteryreport you can generate a report about how your battery is used.
And you can also see what kind of state drained your battery, if this was an active session or a Connected Standby session.
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.
I hope this helps you to troubleshoot Connected Standby issues.
