Windows 8 s3 s4

Although the target system power state is the same between hybrid shutdown and hibernates S4 , Windows will only explicitly disable WOL when it's a hybrid shutdown transition, and not during a hibernate transition.

In Windows 10, hybrid shutdown also known as Fast Startup S4 stops user sessions but lets the contents of kernel sessions be written to the hard disk. It enables faster startups.

And just like on the phone, Connected Standby enables the system to stay fresh, up-to-date, and reachable whenever a suitable network is available. Windows 8 supports Connected Standby on low-power PCs platforms that meet specific Windows Certification requirements.

All ACPI-compliant computers shut off their processor clocks at S1 and lose system hardware context at S4 unless a hibernate file is written before shutdown , as listed in the sections below. Details of the intermediate sleep states can vary depending on how the manufacturer has designed the machine. For example, on some machines certain chips on the motherboard might lose power at S3, while on others such chips retain power until S4. Furthermore, some devices might be able to wake the system only from S1 and not from deeper sleep states.

A user can specify the action to take when the sleep power button is pressed by using the Sleep button action. Power consumption Less consumption than in S0 and greater than in the other sleep states. Processor clock is off and bus clocks are stopped. Software resumption Control restarts where it left off. Hardware latency Typically no more than two seconds. System hardware context All context retained and maintained by hardware.

System power state S2 is similar to S1 except that the CPU context and contents of the system cache are lost because the processor loses power. State S2 has the following characteristics:. Power consumption Less consumption than in state S1 and greater than in S3. Processor is off. Bus clocks are stopped; some buses might lose power. I would suggest just to stay away from Windows 8 for now, seeing people saying im going to sell my pc and get a mac for such a stupid reason makes me sad.

Here's LatencyMon after running for a couple minutes. There were no significant second spikes, and the highest measured latency stayed below us for the 1st minute. Thats really nice. Thanks for taking the time to test with LatencyMon. I realized that the 3 laptops I ve tested Win8 on, are all Intel based like almost all of the pre iX laptops. I don't have any newer machines to test on. SYS cause constant spikes, while on Windows 7 which are based on the same kernel, they work fine.

It would be great if more people with or older chipsets could run LatencyMon on various Windows versions. The mobile chipset is almost 6 years old now; I'm not surprised it doesn't work perfectly with Win8. I have the same issue. I'm running tractor 2. Is this issue on all win8 machines or just the Lenovo ones? Is there a solution for this? You must log in or sign up to reply here.
