Omen Obelisk Desktop 875-1xxx
Microsoft Windows 10 (64-bit)

Lately, when I go to shut down my computer or put it so sleep I've been encountering errors. Often times, when I shut down the computer the system will shut down and the monitor will go black but the tower's fan and lights will remain operational. Also, when I put the computer to sleep the system will hang and become unresponsive but, again, the lights and fan will continue to run. Both of these errors result in me having to manually shut down the computer by holding the power button.

50% is a lot - something is preventing normal operations.


Desktops are not my area of expertise - I can offer a couple of solutions and places to check.


It is either hardware or software - of course, and there are a couple of places to check the software before you start testing the hardware.


Switch off / on Fast Start / Fast Boot


The "fast start" is made possible due to a stored database of the startup features that allow the computer to bypass the slightly slower method of starting the Operating System by reading that information from the disk.


If the database (stored information) becomes corrupt or is out-of-date (same results), the computer will have a hard time shutting down and perhaps starting, too.


The fix:  Switch OFF Fast Start - This deletes the stored startup database and forces the computer to start from the Operating System installed on disk. 


NOTE: If you miss saving that extra few seconds when booting the computer, Fast Start can be switched (back) ON later.


Settings   > System > Power and Sleep > Additional Power Settings >

Choose what the power button does >

Click Change settings that are currently unavailable >

Remove Check (clear box) Turn on fast startup (recommended) >



  • Close programs (browsers, games, email, etc) and close any open windows


Windows key + X (opens a command list) > Click / Select Command Prompt (Admin) >

When the command window opens, type the following command and hit Enter:

shutdown /s /t 0


  • Wait for the computer to shut down completely (a few seconds)
  • Boot the computer > Log in > Wait around for a couple of minutes (yes, wait, do not rush) >
  • Try shutting down the notebook from Windows key > Power


If all now works as expected, and you want to continue using Fast Boot,

Switch ON the fast boot / fast startup setting (optional)



Reliability Report


Although this cool reporting tool has been around for quite a while, it might be overlooked because it is hiding in an unlikely spot in the Operating System.


The degree that the report / monitor can help you depends on whether whatever is going on is something about which the computer is aware.  The report is not quite the in-depth tool as is the Event Viewer - the Report is generally easier to read and interpret and is a good place to start looking.


Windows 7:

Control Panel > set icon view > Action Center


Windows 10:

Control Panel > set icon view > Security and Maintenance >

Under Maintenance > Open the Drop Down Menu >> Click on View Reliability Report


Method to start the Reliability Report software using Command Prompt


Open Admin cmd prompt

Windows key + X + (then) A

Type the command, followed by the "Enter" key

perfmon /rel

After you have done the obvious, that is, all your HP software and drivers are updated / installed and Windows Updates is current, and none of the tools you have used have given you any indication at all about the problem, then it may be time to check / test the hardware.
