    Is DevSlp limited to ULT/ULX on Haswell?

    All the information I've found so far about Haswell's support of DevSlp talks about ultrabooks, tablets and stuff, and ULT/ULX are usually mentioned. But I've not found any documentation on whether DevSlp is missing or not on MB/H versions. Does anyone has a definitive answer for this? How do I check if it's working or not?


    BTW, what's the typical latency to expect from a modern SATA SSD when recovering from a complete power-down?

    Bump. :(

    It looks like not many people care about aggressive power saving?

    In a very obscure Techinferno thread for the W230SS, there were some documents that said that for DevSleep to work, you need specific pins to be present on the mSATA and SATA connectors. To my knowledge, all Haswell chipsets will work with DevSleep though implementation is specific to the motherboard (the pins must be present on the Storage connectors). Supposedly, the latency is within the 50ms range for DevSleep though it is much much longer for a power down.
