Find the Option “ USB Wake Support” and change it to “ Enabled” (from the manual: this option allows you to enable USB devices to wake the system from Standby). Go to BIOS settings (press F2 at the boot screen). Surprisingly, I came up with this solution which worked for me: Too desperate, I went to BIOS settings to see if there’s anything that I could do. However, they may work for you, so you may want to give them a try. Unfortunately, none of the solutions above worked for me. Some said that Dell told them the problem was because of the motherboard, and they sent their laptop to Dell for motherboard replacement. Some said that disabling the Nvidia Display Adapter (in Device Manager console) fixed their problem. Some said that rolling back the Nvidia Driver to a previous stable version fixed their problem. Some said that after upgrading the Display Driver (both Intel and Nvidia), the problem disappeared. Some said that upgrading the BIOS solved their problem. Some said that turning “Allow hybrid sleep” in “Edit power plan” to either On or Off worked for them. Good thing was a lot of other people had the same issue as mine (Am I a little bit mean to think that it’s good because people have problems? :D). Obviously, I went to ask Dr. Google for the solution. Then I had to hold the power button for 10-20 seconds several times to do a hard shutdown, then started it up again. 
If I held the power button for 10-20 seconds, it might wake up if it wanted to, or just kept staying dead if it decided that it needed some more sleep. Whenever the laptop went to sleep, it wouldn’t wake up even if I opened it only several minutes later. Then after some other Windows Updates, I believe, the problem became more serious. I believed that after some Windows Auto Updates, the problem began.Īt first, I noticed that if I left the laptop sleep through the night, when I opened the lid the day after, sometimes it froze at a black screen. This happened more and more frequently over time. I bought my M3800 and upgraded it to Windows 10. If you own a Dell Precision M3800, you may have faced the common Dell Precision M3800 sleep issue, where your laptop freezes at a black screen when you try to wake it from sleep.
