Windows Unexpected shutdown after hibernating or standby.

You could try enabling hibernation by doing the following:

— click on run as administrator
— type the following command in command prompt:

Powercfg -h on

— this command will enable hibernation in your system
— try setting your system in hibernation

If all the settings are good on power settings page then

1. Run CMD.EXE as administrator
2. Run the following command: bcdedit -enum all

Look for "Resume from Hibernate" in the output from the command above(example below):
Resume from Hibernate
---------------------
identifier            {3e660eaf-2f71-11e5-bc20-d60bd45012e4}
device                 partition=C:
path                    \Windows\system32\winresume.exe
description         Windows Resume Application
locale                  en-US
inherit                 {resumeloadersettings}
recoverysequence         {3e660eb1-2f71-11e5-bc20-d60bd45012e4}
recoveryenabled            Yes
allowedinmemorysettings 0x15000075
filedevice                      partition=C:
filepath                         \hiberfil.sys
bootmenupolicy            Standard
debugoptionenabled      No

3. Once you have found it, copy the value for identifier (in this example - {3d8d3081-33ac-11dc-9a41-806e6f6e6963})

4. Run the following command: bcdedit /deletevalue {3e660eaf-2f71-11e5-bc20-d60bd45012e4} inherit

Example : C:\Windows\system>bcdedit/deletevalue {3e660eaf-2f71-11e5-bc20-d60bd45012e4} inherit

The operation completed successfully.

5. Test hibernation

6. If still you have the same problem then update the display drivers. If no update is available, uninstall all the display drivers, restart the PC, install the drivers, restart the PC and then try hibernation.
