There can be many reasons why a computer will not go into standby (S1, S3)
or hibernation (S4). The most common cause is some application or process
that continues to run, preventing the computer from ever reaching the time
alloted in the Power Options settings. Tracking this down can be maddening.
First, the good You can manually put your computer into standby or
hibernation. This means that your hardware can do it. That leaves you with a
software issue.
Microsoft has described some of the more common software issues in its
knowledge base; if you're lucky one of these will apply to you (see the KB
for details). All these can interfere:
* a Direct 3D or OpenGL screensaver
* setting a delay of more than 45 minutes in Power Options
* certain video adapters.
Search the KB with 'enter standby' for more information.
Some contributors to the Dell Community Forums (I own a Dell) have had
success by using one of the other Power Options settings (besides
Home/Office Desk), but this may be because desktop users generally don't
ever change these.
If none of the above helps, you are left with a time consuming
trial-and-error process of elimination. You may never solve your "pesky"
problem. But if you do...post your solution here!

Hi Rocket J,
Thanks for your reply but that doesn't really help. I am struggling with
an issue where my PC will not go into standby / hibernate. I can fore it
via task manager so I know it works but the activity using the Control
Panel - Power settings don't work.
I have done all the obvious things from chipset INFs to BIOS flashing to
latest drivers for everything but still no deal. My only thought is that a
rogue task is active somewhere but not active enough to register on the
Performance Monitor.
I installed a new motherboard and graphics card and the problem has
surfaced since then. The very helpful people at Aopen have been unable to
recreate the problem using the same hardware config so it must be in my
system. sigh!
