My laptop has windows 7 home premium nothing special. Recently like a few days ago I have noticed when I put my laptop into sleep mode and close the lid then a few hours later open the lid the laptop has been shutdown unexpectedly so i have to hit start windows normally each time. I have a dell Inspiron 1526 laptop and this has started a few days ago. Anyone got any ideas as to why this is happening? Wanted to point out that the laptop goes into sleep mode then when i open the lid of the laptop it says it shutdown unexpectedly.
