![]() If device initiated interface power management is enabled, the device shall not attempt to initiate an interface power state transition between reset and the delivery of the device reset signature.ġ3.3.7 Enable/Disable Device Automatic Partial to Slumber TransitionsĪ Count(7:0) value of 07h is used by the host to enable or disable Device Automatic Partial to Slumber transitions. The enable/disable state shall be reset to its default disabled state upon COMRESET. The enable/disable state for device initiated power management shall persist across software reset. The host may enable device initiation of such interface power state transitions for such cases where it may be desirable for the device to attempt initiating such transitions. By default, the device is not permitted to attempt interface power state transitions by issuing PMREQ_PP or PMREQ_SP to the host. This allows the host to asynchronously transition from Partial to Slumber.īit 14 indicates that the device supports Automatic Partial to Slumber transitions and may asynchronously transition from Partial to Slumber when enabled.ġ3.3.3 Enable/Disable Device-Initiated Interface Power State TransitionsĪ Count(7:0) value of 03h is used by the host to enable or disable device initiation of interface power state transitions. The device shall tolerate a Partial exit latency up to the max Slumber exit latency. The exit latency from this state shall be no longer than 10 ms.ġ3.2.1.16 Word 76: Serial ATA capabilitiesīit 9 when set to one indicates that the Serial ATA device supports the Partial and Slumber interface power management states when initiated by the host.īit 13 indicates that the device supports host Automatic Partial to Slumber transitions. The common mode level of the AC coupled transmitter is allowed to float (while maintaining zero differential) as long as it remains within the limits cited in Table 29 entry AC coupled common mode voltage. ![]() Slumber => The Phy logic is powered, but is in a reduced power state. ![]() When Automatic Partial to Slumber Transitions are enabled the exit latency from this state shall be no longer than the maximum Slumber exit latency. The exit latency from this state shall be no longer than 10 us unless when Automatic Partial to Slumber transitions is supported. Both signal lines on the interface are at a neutral logic state (common mode voltage). Partial => The Phy logic is powered, but is in a reduced power state. The interface is synchronized and capable of receiving and sending data. PHYRDY => The Phy logic and main PLL are both on and active. The interface power states are defined as described in Table 50. Your initial question was 30 minutes anyway.Serial ATA interface power states are controlled by the device and host controller. Just accept that there is a 4 minute delay. My recommendation would be to go for option 1. Do note that this will increase the overhead of the system and may hurt performance if coded inproperly. Instead create a program or script that measures activity and perform the launching of the task yourself. Accept that there always will be a delay of 4 minutes. ![]() In windows 7, it doesn't care for the 3 previous minutes. Task scheduler gets the message, sees your task which is set, idle for 1 minute and thinks: Oh, we should've started you 3 minutes ago. When the system becomes in Idle state after 4 minutes, the OS announces: the system is now idle for 4 minutes, and counting. The exact reason why is unknown, but it is probably for optimization reasons and possible complaints. Windows starts detecting that a system is idle but ignores it for 4 minutes. Microsoft basically programmed Windows to say: A computer is considered Idle if for 4 minutes, no user input was generated. I've noticed on the Microsoft docs that it says something about 4 minutes but I didn't understand and I don't know if it's related or not? and why it doesn't work at all on my windows 7 machine.īelow is how my scheduled task looks in task scheduler: Any explanation? and how I can run it after 1 min of idle time not 4 mins? Also the same task doesn't trigger at all on windows 7 as described here I've manually timed it more than 5 times and it always runs after 4 mins not 1 min. I've checked and manually timed the trigger to happens and it always triggers after 4 mins when no keyboard or mouse actions, not 1 min. In my windows 10 machine I have created the below task scheduler task and set the trigger time to be 1 min when idle.
