fixing hibernation issues on Windows 7

I've got several Dell laptops (Latitude E6410, E6230, E6220) with trouble resuming from hibernation.  What I'm seeing most often is the laptop will begin to resume and then sit at the Welcome screen and never go any farther.  I'm going to make this my standard protocol for troubleshooting hibernation issues:

The short version:

  • update all hardware drivers
  • disable and re-enable hibernation to delete and recreate the hiberfile.sys
    (run powercfg.exe /hibernate off and powercfg.exe /hibernate on)
  • in device manager, turn off all devices that are capable of waking the computer (particularly NICs)
  • turn off the auto-hide task bar
  • in power options -> advanced settings for the active power profile, disable hybrid sleep
