What to do when your Surface devices don’t sleep

Starting Windows 8 Microsoft introduced a sleep state called Connected Standby (CS). Think of this sleep as your smartphone when its screen is off, the device is still running, connected to the mobile networks, capable of receiving notifications and wakeup calls etc.

In early days this feature was supported only on WOA… you know it as Windows RT.. yes something many wouldn’t care to remember.. Windows x86 / x64 SKU officially support CS starting with Haswell processor. Haswell introduced a sleep state S0. This keeps part of the device sufficiently awake to receive notifications etc while in low power state.

It never truly worked for me. I had one of the first engineering models from Intel delivered in June 2013 and the device refused to wake up properly. I tried just about everything and while things have gotten better, for people like myself, battery life is more important than notification (which I already get on my phones). A few times SP4 in CS has had around 50 – 90% drain in few hours ( 2 – 4).

The solution is easy – unless CS is something you rather than instead of longer battery life, you should force system to hibernate rather than go into connected standby.

Switching to hibernate:

  • press Start Menu and type power options
  • open Power Options from Control Panel.
  • tweak Choose what power buttons do option – enable hibernation and set desired settings
  • tweak Change when the computer sleeps – I prefer a short sleep
  • next click Change advanced power settings
  • Navigate to Sleep > Hibernate After > Ensure duration is correct.
  • Click  Ok and close all power options.
