Tried days, still no luck.
It should look like this not looks like my MacBook Air.

Do you know any possible solution where I can find to fix this issue?

Do you have any possible solution to fix this issue?

I always thought it was related to system definition, but you are already on iMac18,2 and it's not working...

 

[ryouitou]

It's iMac18,2

And also my PCI section did not show anything, just show this:

This computer doesn’t contain any PCI cards or devices. If you installed or connected a PCI card or device, make sure it is properly installed.

And also my PCI section did not show anything, just show this:

That's normal behavior.

 

[ryouitou]

That's normal behavior.

It's normal that section not showing anything?
But my friends' showed.

Go to an Apple Store and look in System Information for a real iMac, it shows the same thing.

I don't have local Apple Store around, but let me check my MacBook Air first.

and... yep, it did show nothing.
Problem solved, but still can't fix the sleep issue. (sigh)

What happens when you try to put the computer to sleep?

What happens when you try to put the computer to sleep?

When pressing sleep in the Menubar>Apple>Sleep, system will get into the sleep procedure.
a few moment later, system power off as I expected.
Just about 3-4 sec, it turn back on and looping sleep/wakeup.

But I have already solved half of it, it's now sleeping like a old mac with blinking power led light.

As the image that I replied in last page, my system doesn't recognize 'Hibernate Mode'.
And I really don't know how to fix that issue.
