System Will Not Go To Sleep

Dell XPS 8960 (Purchased September, 2024)
Intel UHD Graphics 770 (Embedded)
NVIDIA GeForce RTX 4060 Ti (In use)

I have spent so much time looking for solution to put my system when it reaches it's set time. It will not go to sleep. The display will turn off at set time, but not the system.
I have been working with Dell. Every time they send me some links, they all will NOT be for Windows 11. I spoke to the support, still not help. I was asked if the system can be sent to them to troubleshoot, and returned to me, at their expense. This will be a logistical nightmare, for my PC not going to sleep. It's my work PC.

When "Make my device sleep after" reaches:
- Power button light goes off.
- Graphic card light stays on.
- Processor fan keeps running.
- Power supply fan keeps running.
- Power supply light stays on.
- Hard drive light keep blinking.

So, the only things that stay on are the monitors and the power button light.
Please, if you have any solution for me to try, please, please, let it be for Windows 11 Pro.
Everything I get from Dell, I cannot find the section to select what am supposed to select.
Since Dell is not helping me find the solution, I now come to the community for help.

By the way, I have updated all possible updates for Windows and for Dell, including the BIOS.

Cheers

Try sending it to sleep and then if it still doesn't do it, open a elevated command prompt and type in:
powercfg /requests

then post a screenshot of it here, this is just to see if anything is preventing it to sleep.

Then try running the IdleClock.exe from the attached and keep your hands off the mouse and keyboard, the clock is suppose to get bigger and if it resets to 0, that means something it resetting the idle clock.

The IdleClock keeps to the same size; the timer just running.

All of a sudden, my laptop also would not go to Sleep, so I'm using Hibernate. That also works when I close the lid.

@Caxtin - That part looks good, I am out of ideas at the moment. If I think of anything, I will comment again.
