Computer fans, LEDS, and the HDD light stay on after shutdown. Power Management tab missing in Win7.

On my custom pc, Windows 7 shuts down completely, but the fans and fan-LEDS stay powered, while the HDD light just stays on without flickering. After looking at similar threads, I believe I need to check "allow computer to turn off device" in device manager, but when I go to do so, the power management tab in the Properties dialog is missing. Under Device Manager, "Computer" is listed as "ACPIx64-based PC," and it also finds zero drivers when I open its properties and click, "Driver Details". It seems as if its being treated as this completely different entity under Device Manager.

My computer works fine otherwise. It's just annoying to have to hold down the power button every time I want to shut it down.

What settings can I change to fix this? I unfortunately haven't found any corresponding options in the UEFI.

Specs:
AsRock Z87 Extreme4 motherboard
Intel i7-4770K CPU
Seasonic 550W PSU
Corsair 500R Carbide Series (Has front and side panel fans)

Thanks in advance.

I was going to update the BIOS, but I've seen lots of warnings against it. Right now I have UEFI version P1.30, but I don't think that an update will really fix the problem.

I'm still puzzled as to why Windows isn't even showing the option for allowing permission to turn off the computer.

Once in a while my computer does shut down properly, but 90% of the time the above happens. It also frequently won't wake from sleep mode.

What warnings were they? :)  BIOS update is something you do exactly in the situation like this - when something is not working as it is supposed to.

Let me tell you this: this is not a Windows configuration problem.

The BIOS update is made out to be pretty risky, like on that link: "We don’t recommend users to update the
BIOS if their system is already running normally." But I guess it makes sense, so I'll try that. That's probably just there for warranty issues anyway.

What's also weird is that sometimes after I force a shutdown by holding the power button (after the display sleeps and Windows is off but the fans are still running), Windows boots up on the black screen where it asks if you want to boot in Safe Mode or not. But this only happens once in a while.

Unfortunately it looks like updating the BIOS didn't do anything

Are you guys 'tweakers'?

Are you looking for superfast shut-downs and maximum performance?

I'm just wondering if there have been tweaks made that shorten the shut-down process.

The thing is, sometimes devices are busy when the shut-down operation commences and normally, busy processes are given about twelve seconds to respond and in most cases, they respond in much less time.

But, when you mess with the 'WaitToKill' settings in the registry, as some optimisation software does, then you risk picking times that are too short and processes that disconnect hardware don't get a chance to run.

It's a bit like this: imagine you're in a room and someone says you have to leave this room soon. If there is no panic, then the room can be tidied up can't it, and someone can remember to switch the lights off on the way out, can't they?

But imagine if someone said you had to get out now? You know, like GET OUT NOW!?

Imagine, it would be bedlam. Everyone would try to get out but there wouldn't be time to turn of the light, would there?

And there would be cups on the coffee-table and everything, wouldn't there?

It's like that with computers; if you tell it to shut down NOW, it's bedlam, the computer has no time to do the housecleaning and lights get left on whilst cups fester on the coffee table, don't they?

What's the rush, mate?

Un-optimise it.

Unfortunately I never resolved the problem, and I'm not sure what to do exactly.

I stopped following the issue, but by default I'm leaving the thread open and unresolved. Someone more experienced here, does this sound right?

Too all the people with this problem or something very similar to this.....You shut off computer tower....Windows OS shuts off completely....but the fans and lights stay on forever unless you hold down the power button or unplug the PSU? I had the exact same problem with one of my computers spent hours changing power management settings in Windows OS changed settings in the Bios.....Flash my Bios to latest version available....The problem never went away stayed the same......Even got worse to the point that even when I would hold down the power/start button didnt matter how long I pushed it....the computer would not shut off! I would have pull the power cord out of the PSU to get the machine to go off! I spent hours on all these tech forums reading/researching the problem and seeing what if any possible fix there was....and how it was done....to my amazement NO BODY POSTED ANYWHERE THE FIX OR SAID THAT THEY HAD FIXED THE PROBLEM>>>>> I AM HERE TO SAY I FIXED IT! It only took approx. 20 minutes.... THE FIX >>>>> CHANGE YOUR PSU!>>>BAM! PROBLEM FIXED! Everything boots down perfectly and boots up perfectly! YEAH! I cant believe I waited so many weeks before trying to "just change the PSU" thats all there is to it. TRUST ME! You have this type of problem 9 out of 10 ITS YOUR PSU! Regards to all and hope that helps you! (=
