Vista's sleep function is supposed to both standby and hibernate, allowing me to lose power. The stand by part of that works fine for me. However, recently, it is not doing the hibernate part. If i kill the power it has to boot completely and complains that vista was shut down wrong. I have ~200gigs of hd free space, so thats not the issue. Any ideas?
