Okay, so I'm having a problem with my Dell Precision M4400 and sleep mode. When I close the lid, it won't resume from sleep. All the drivers are up-to-date and it is running Windows 7 Ultimate 64 bit. |

I'm guessing a driver is to blame. When did the problem first appear, when did you upgrade Your drivers before that, and which driver was it? Have you added hardware recently? |
