Agreed. Their BIOS is full of bugs. I've investigated a few on the 7275 (business grade): I believe it's technically impossible for it to really sleep on Windows, regardless of how you look at it. It just saves a little bit of power while it looks like it's sleeping, then Windows realize it's an unacceptable power draw and pulls the plug (power off) then transparently resumes from a S4 hibernate to disk.
