Now we can reenable Connected Standby / Modern Standby. Change the value for “Processor power management” > “Maximum Processor state” to 60% for “On Battery”, and to 50% for “Plugged in”.

Change the value for “Processor power management” > “System cooling policy” to Passive, for both “On Battery” and “Plugged in”.

All hidden settings are now unlocked! Make the following changes: Select the Tablet Mode power plan, click “Change plan settings” then “Change advanced power settings”. In Control Panel > Hardware and Sound > Power Options, click “Create a power plan” in the left panel, and create a new power plan named Tablet Mode. Open Register Editor (regedit), change the value for the key: HKEY_LOCAL_MACHINE\ SYSTEM\ CurrentControlSet\ Control\ Power\ CsEnabled In order to unlock the hidden advanced settings, we need to temporarily disable Connected Standby / Modern Standby. However, if we clicked “Change plan settings” then “Change advanced power settings”, we found that very few advanced settings were available! On every Surface device, Connected Standby / Modern Standby is enabled and a predefined power plan called Balanced is loaded by default.

Background activity while the system is “off”.

There are some claimed advantages of using Modern Standby:

Microsoft introduced a new feature called Connected Standby in Windows 8, which has been expanded to Modern Standby in Windows 10. Assuming the clock speed is stuck at one frequency (even immediately after booting when the computer is still cold) and that the CPU temperature sensors seem to work, then it's probably because quiet mode is enabled.In factory condition, the fans of my Surface Pro 3 ran almost non-stop, emitting a very audible crackling sound, even when the system was under very light load! In this post, we document how I throttled the CPU speed, and essentially turned my Surface Pro 3 into a passively cooled tablet. You can see similar throttling (normally temporary) if your fans are broken or don't work well. I think in active cooling mode both fans and throttling are used but throttling is only enabled if your computer runs hot even with fans active.) (Such as the "system cooling policy", which can be set to either active cooling ( fans) or passive cooling ( throttling). There are power settings in Windows that will similarly throttle CPU speed to reduce power consumption. You should also restore other power settings to their default values after toggling "quiet" or "fan-less" mode. From my experience with this issue on Windows 7/8 the only way I could disable it was using the keyboard. I'm not sure if the setting can be disabled by software. (Of course with the fans disabled it won't stay very cool.) It is supposed to make the computer draw less current and thus run cooler. This mode locks the clock speed to its minimum value.

The frequency is usually some multiple of 400 MHz or 800 MHz on consumer Intel machines. Your CPU is capable of running at variable clock speeds. If it's not controlled by the keyboard then it's possible that it's a BIOS setting. It's easy to accidentally enable if it's one of the function keys alongside volume control, screen brightness, keyboard backlight, etc. On some laptopts it's controlled using the keyboard. It tries to reduce how much heat your computer produces and disables fans.
