Thank you Magic Andre so, so much . You nailed it with the disc cache! It needs to be activated in Device manager by right licking on the HDD, properties, guidelines and activating the write-cache. Result: Hibernate delay has been reduced from +10 Minutes to about 10 SECONDS! I would probably never have found it without your hint. Absolutely wonderful! Regards, barley

Hi, thanks for your insightful discussion. My XP system suddenly takes +10min to hibernate. Wake up and turn off are normal. I made an etl file, but I always get an error when trying to produce an xml file from it - in XP as well as Win7. Therefore I uploaded the .etl file and hope you would be so kind and take a look at it. http://www.box.net/shared/kpjxta9k5bokmypo80cs Kind Regards, barley
