Apparently this is a somewhat popular bug with Lenovo and disks that are no longer recognized after resuming, if password protected.

See here for a potential fix: http://support.lenovo.com/en_US/detail.page?LegacyDocID=MIGR-72837

Even if that works, update the BIOS and the firmware for your hybrid, just to be on the safe side.

HTH,
Dan
