Windows 8 sleep mode not working

Hi all, for some reason when I go to power and hit sleep in windows 8 it doesn't work, after a few seconds the hdd light stops flashing but the case fans and case lighting stays on. The monitor goes into sleep mode. It just won't wake back up. Pressing the power button, moving the mouse, pressing the keyboard and mouse buttons. Nothing wakes it up. I have to hold the power button to force it to turn off.

Why is it doing this?! It worked fine on windows 7.

I always have several tabs running in chrome and a few open program's and this have never been a problem, so I like to use sleep mode then carry on where I left off. I don't fancy having to fully shut it down every time I wanna watch the tv quietly then have to boot it up from scratch again. (The fans can be pretty loud) help please :bounce:

There are many responses to similar questions in other forums that Expat Shield's core proxy drivers are the cause, fixable by uninstalling Expat Shield. I was having the same problem, and that cleared it up immediately.

thanks - looks like its the graphics card...

PCI Express Active-State Power Management (ASPM) has been disabled due to a known incompatibility with the hardware in this computer

I reset the CMOS, adjusted the ASUS motherboard power settings using the Asus AI and hey presto, seems to be working OK, although still have the ASPM error which checking the energy report.

I have a similar issue with my Sony Vaio.
It doesn't go into sleep mode at all. I can shut it down and restart it but sleep mode is just a black screen with the fans blowing etc.

How do I fix this. There's a ton of topics on this problem online but I haven't found any fix...

My graphics driver is up to date apart from the sleep mode issue everything works fine. I already disabled hibernation etc, that fixed one problem, because before I couldn't shut it down as well. But the sleep issue remains

Best solution

I came here looking because of the same issue. Installed W/8 64 bit upgrade from XP (and it actually did not touch my XP which was on a different drive, though i later deleted it) and at first it would not even sleep. It would just go into hibernation when you hit sleep (Windows key and "i" and hit power).

After more updates, including one i obtained for my Intel network card, it would go to sleep for a couple seconds and then wake back up.

The solution was to go to Network connections (Windows key and ^), R. clk.>Properties>Power Management and deselect anything under Wake on Lan.

Or go to Device Manager (Windows key and Pause/Break and look left) and Network Adapter>Properties and follow the above.

Before this got fixed i also got the below error because of it, which others have received as well because of this:

"The platform firmware has corrupted memory across the previous system power transition. Please check for updated firmware for your system."

In any case, there is no firmware for this old Asus P5LP-VX Intel 945p system.

Hope it helps.

What worked for me was
Network Connections | Wi-Fi Properties | Configure... | Power Management |
"Allow the computer to turn off this device to save power" - Check the box.

I tried a LOT of other things, but this was my magic 'bit'.

OMG... actually daragh, YAMG (you are my god)... I have been struggling with this problem on a brand new Dell Latitude 10 tablet with Win 8 Pro for the last 8 hours. I was about to box the unit for return when I ran across your post. Bingo! Problem solved... THANK YOU SO MUCH! Right out of the box, the unit would go to sleep and not wake up. I spoke with two separate "new order" specialists at Dell who connected to the device remotely and could not solve the problem after a combined 2+ hours on the phone! By the way, Dell has no clue (nor did I) that the power button is not to be used to sleep and wake up the device. At least I could not get it to work that way. On the Dell Latitude 10, the Power button is for hibernate and shutdown/restart only as far as I can tell. You have to put the device to sleep by using Charms/Settings/Power/Sleep. It is much easier to force my iPad to go to sleep. :)  Thanks again!

I'm hoping this thread continues until there are solid solutions to the problem. My new system (windows 8 pro) will not shut down, hibernate or sleep. When you shut it off it really doesn't shut down - the power light stays on, display off, and will not come back on unless you hold the power button down for a while. Then you can power back up.
I have tried the "what your power button does" changed the fast boot on and off, the hybrid sleep, and many other settings. Nothing is working.
I'm not sure if it is a lenovo problem or a windows 8 or both.
Hopefully someone will come up with something.

I got the power report if anyone wants to take a look at it. Since it is so long i wasn't sure whether to post it first or not.
