The Intel® SSD 530 Series has new low power features designed for Ultrabooks and low consumptions PC's, this includes the DevSleep functionality.
The SSD itself does not require any special driver nor configuration, however, some older systems may not be fully compatible with newer power saving features. We advise you to check the Computer Manufacturer Support Websites, confirm that you are using the most recent BIOS available for your PC, as well as updated chipset/storage controller drivers, also, check with them if your system supports Devsleep.
In some cases, you may be able to prevent this type of issue by disabling fast boot or other similar technologies in the BIOS.
If the issue persists, we advise you to Contact Support, engage your nearest Intel support center so they can provide details on managing low power features of the SSD.
Thank you very much for your reply!
I have posted additional info on asus forum and have contacted technical support, we'll see what their reply will be.
