Latitude Sleep/Wake Issue

This is a known issue that is happening with the Latitude E6430 model.

Here are some known information:

• Comes with A12 bios; the latest on the Dell website is A13. Release date 10/17/2013. This update does not fix the issue.
• According to forums, disabling Hibernation will fixes the issue. Hibernation is disabled by default by PXE Image. Does not fix the issue.
• According to forums, the cause can related to webcam or graphics drivers.  
• When the computer is attempted to be awaken from sleep, the screen remains blank but the computer is on. Requires a hard-restart in order to bring screen back on.
• Occassionally causes blue-screen error - Error code 1033 - run sfc /scannow before continuing if you observe this error
  

 Disabling the SD card reader in Device Manager removes the sleep / wake issue - it is (currently) the only work around that works on all the laptops we've seen with this issue.

Fix for 6420s (and possible 6430s) - Update with the proper card reader driver directly from Dell. LanDesk will sometimes take the card reader from newer laptop models

Correct driver for E6430s - http://www.dell.com/support/drivers/us/en/04/DriverDetails/Product/latitude-e6430?driverId=54WK9&osCode=W732&fileId=3215914513&languageCode=en&categoryId=CS
