My laptop sometimes does not resume from Hibernate with its screen active on the desktop, I get a black screen. This is the new one running Windows 7. It's strange because while Windows is starting I get the main screen OK with the normal logo and saying Windows is resuming but then the screen goes black. If I plug in my external monitor without doing anything else the desktop is there exactly as it should be on the laptop screen. So far I have not been able to find anything, I have found suggestions on the net about making changes to the bios settings but these were for a desktop and the laptop does not have the relevant bios options. W7 is fully up to date as are the drivers for the video. In case it matters it's an Acer Aspire 5742. I should add that Sleep mode always works fine, only Hibernate exhibits this symptom.
Anyone have any ideas about this please?
