The recent Surface Pros (starting with the SP3) and some other 2-in-1s support a Windows feature called Connected Standby or InstantGo:
which is different from the traditional suspend-to-RAM sleep state. As I understand it the device stays connected to wifi while sleeping and can perform background tasks, but as a result there is more battery drain than with normal suspend-to-RAM.
Linux operating systems don’t have support for InstantGo. On the SP3 and above, the normal suspend-to-RAM that most laptops and desktops support (ACPI S3) is disabled, meaning that to sleep you have to suspend to disk/hibernate (ACPI S4), which means a much slower resume. Some other 2-in-1s do support suspend-to-RAM, making them better choices for dual-booting Linux.
So, what sleep states will the V support? I am hoping that ACPI S3 will be an option because I am interested in running Linux on it.
