Windows 7 won't go into sleep mode

Specs:
Desktop with Windows 7 pro 64bit

Problem:
Desktop won't go into sleep mode.

For months my computer would manually go into sleep mode. Settings were set to turn off monitor after 15 minutes and go into sleep after 25 minutes. While file sharing the computer would not go into sleep mode (my setting).

Today I noticed that even when I'm not file sharing the monitor would turn off, but the computer would never go into sleep mode as scheduled.

What I've done:
(1). Checked to make sure my drivers are up to date, which they are (especially my video card), wake timers are turned off, etc.

(2) Ran CMD as admin (Start > cmd > right click, run as admin) > power -energy. After a minute i received:

Platform Power Management Capabilities:Supported Sleep States
Sleep states allow the computer to enter low-power modes after a period of inactivity. The S3 sleep state is the default sleep state for Windows platforms. The S3 sleep state consumes only enough power to preserve memory contents and allow the computer to resume working quickly. Very few platforms support the S1 or S2 Sleep states.
S1 Sleep Supported true
S2 Sleep Supported false
S3 Sleep Supported true
S4 Sleep Supported true

An active remote client has recently sent requests to this machine.

I haven't touched anything after that. Any help to understand what the problem is and how to solve it would be greatly appreciated. Thank you!

 

i can manually send the computer into sleep mode, but it won't go to sleep as scheduled.

 

any solutions????

 

Do you normally shutdown your computer at night or leave it in sleep mode? If you haven't done a full shutdown and restart since this problem started, I suggest you do so and see whether that resolves the problem.

 

normally i leave the pc alone and allow it to enter sleep mode at night. I restarted the computer when i noticed the problem prior to making the thread.
