|Hibernate mode can be troublesome with USB powered devices. Good concept, not so good in practice, and it's got nothing to do with any configuration issues, it's just an an unfixed issue (unfixed by Microsoft, that is).|
Put your PC to sleep instead (desktop keyboards often have a "Sleep" key, with "Wake Up" key next to it). Much less troublesome and just as effective in conserving power and reducing wear and tear.
