I have a dell precision M4700 that when it goes to sleep, it will not wake up and only displays a black screen. The only way to get it back up and running is to perform a hard reboot. I have changed the sleep options to 20 minutes and changed advanced power options to never put the hard drive to sleep. Have had no success. Updated the BIOS, chipsets and graphics drivers (AMD Fire Pro). Any other suggestions?
This laptop is on a Dell docking station and the power button does not wake it up either. I ran SFC and Troubleshooter against the Power settings. SFC found and fixed some issues and Troubleshooter made some adjustments to the power settings which may be overwritten by GPO. If anybody has any other suggestions?
