MILAN0 Posted March 26, 2009 Share Posted March 26, 2009 When I shut my cover or enable sleep mode I hear HDD stops working, display becomes dim but CPU fan works. Lights of bluetooth and power on still up. It wakes great from this point. Hibernate mode is set to 0 or 3 is the same situation. Could someone help where to start from?
