![]() Modern Standby systems are recommended to support all wake scenarios for which they have the necessary hardware. wake on fingerprint or wake on optical disc drive ejection (some Modern Standby systems may not have a fingerprint reader or optical disc drive). Some wake sources are hardware-dependent, e.g.Differences are noted in the tables below. Wake source operation may differ depending on whether the system is plugged in (AC power) or on battery power (DC power).Wake source operation and scenarios are the same for all Modern Standby PCs, regardless of whether they are based on the x86 or Arm processor architecture.The following rules govern platform wake behavior: The difference between waking the SoC and turning on the display is central to delivering the Modern Standby user experience. Some wake sources should be capable of generating a wake signal for an event that would cause the system display to turn on. Enabling the real-time nature of Modern Standby is primarily a function of platform devices waking the SoC for the correct events at the correct times.Īll wake sources in the Modern Standby PC are expected to be capable of waking the SoC from its deepest idle power state. During Modern Standby, the networking subsystem stays connected so that the system can wake and instantly respond to incoming emails or VoIP calls. Achieving long standby battery life is primarily a function of allowing all devices, plus the core silicon or System on a Chip (SoC), to enter a very low-power idle state. (The Modern Standby PC uses any available network connection-Wi-Fi, mobile broadband (MBB)/cellular, or wired Ethernet.) And the Modern Standby PC, connected or not, also has very long battery life in its screen-off state, just like a cell phone.Įnabling the Modern Standby user experience requires all of the devices and software in the Modern Standby PC to actively and correctly participate in system power management. However, a PC in Modern Standby remains on and connected to the Internet, just as the cell phone remains connected to the cellular network. Similarly, when a PC is in Modern Standby, it looks and feels off-the screen is blanked, the system has no visible LED indicators, and there is no acoustic noise. The phone remains asleep until the user presses the power button again, or a phone call, email, or instant message is received. When users finish using their phones, they press the system power button and the cell phone enters sleep mode. The Modern Standby user experience is designed to model that of a cellular phone. Overview of Modern Standby user experience for wake System integrators should use this information to ensure that their hardware platforms, firmware, and software can configure wake sources to achieve the required behavior. It also explains which wake events should turn the screen on and which wake events should allow the screen to stay turned off. This topic describes the types of wake sources that must be able to wake the processor. Now let's look on the drivers in Wired_driver_26.4_圆4.exe \PRO1000\Win圆4\NDIS63\ there is e1c63圆4.inf here we can find 82579LM and in turn Powermgmt.reg - Note that these settings are in regards to "wake from sleep" (this is driver ver ,12.15.31.4) So if you want' these settings, make sure to install a driver that has them.Ī quick search found this that especially mentions the NIC in question.A PC that supports the Modern Standby power model must be capable of waking from standby in response to certain events, even if the platform has entered a very low-power idle state. Enables SB power to NIC, other settings are irrelevant.Super IO is configured in NVRAM to react to WOL signal from NIC.but on system reset, and power off, they would be irrelevant.Ĭonsider for a moment that you turn of the machine by pulling the plug, this resets the NIC entirely, now plug in the power, and use WOL to start the machine, note that no Windows driver would have had the chance to modify the registers on the NIC to modify WOL settings. Sure, NICs have registers that can be modified to change features, but few (if any) store these, so the only time any options in a windows driver would have any effect is after windows boots, so potentially when a machine goes to sleep. Not all features that a NIC has can be changed in all versions of the Windows driver, and some features can not be changed at all. When I think about WOL I think about power on from power off mode. Yes, 82579LM has WOL, I have not seen any NIC that does not have it since NE2000 nics.
