The system firmware has changed the processor's memory type range registers (MTRRs) across a sleep state transition (S4). This can result in reduced resume performance.

Hi Themopar,

Thank you for posting your query in Microsoft Community Forums.

From the issue description I understand that the Windows 8 computer will not wakes up from sleep.

I would suggest you to perform the methods and check if it helps.

Method 1

Let’s run the power troubleshooter and check if that helps.

a) Press ‘Windows + W’ key on the keyboard.

b) In the search box, type ‘Troubleshooting’, and press enter.

c) Click on ‘System and Security’ and click on Power click on next to run the troubleshooter.

Method 2

I would suggest you to uninstall and reinstall the display card drivers in Windows 7 compatibility mode and check if that help.

Step 1: Follow the steps provided below to uninstall the display drivers.

a) Move the mouse to bottom left corner and right-click on the ‘Start icon’.

b) Select ‘device manager’.

c) Expand ‘Display adapter’ and right-click on ‘display adapter’ and select ‘uninstall’.

Step 2: Follow these steps to install the drivers in compatibility mode and check if that helps.

a) Download the display drivers from the manufacturer’s website.

b) Right-click on the driver and click on ‘properties’.

c) Click on the ‘compatibility’ tab and check the box ‘Run this program in compatibility mode for’ and select Windows 7 operating system from the drop down.

d) Click on ‘Apply’ and click ‘OK’ and run the file to install it.

Method 3

Follow these steps and check if it helps.

a) Press Windows Key +W, type "Shutdown Settings"

b) Click the "Settings" Icon on the right of the screen.

c) Click "Change what the power buttons do" on the left of the screen.

d) Click "Change settings that are not currently available"

e) Scroll to bottom of Dialog box.

f) Uncheck the box titled "Turn on fast startup (recommended)."

g) Click "Save Changes" button.

h) Exit Power Options Dialog box.

Method 4:

I would have you download all the latest Windows Updates. You can also download the latest BIOS and firmware updates from the manufacturer’s website. You may ask the manufacturer for assistance in this regard.

Ehhh... These canned responses don't hold water. I've seen this error on this forum multiple times, as well spread throughout the internet.

This is an issue.

Hi I have a similar issue with Sleep in Windows 8 Pro (64-bit).

Normal shut down / boot is fine.

Hibernate is fine

Only sleep is a problem.

If sleeping for a short period with the powerlight pulsing the system resumes fine. However if left for an extended period, e.g. overnight. Then the powerlight is out.

Pressing the power button result in failure to boot - powerlight comes on briefly, then POST, then dies.

Second press boots the system, stating in the log that the system failed to shut down cleanly.

So basically in the sleep condition at some point the system 'powers down' ' 'dies', this is neither hibernate (which is set to never) or shutdown. And neither has the battery depleted causing a low power / critical level condition causing hibernate as the battery will be close to full (>90%) on a successful boot.

Obviously any open documents / work is lost in this condition as power to RAM is lost and hibernate does not occur.

I have tried disabling 'fast startup'

BIOS and all drivers are latest

Windows updates all installed.

Have tried a restore from factory image and re-install of all the above and problem remains. 

Any help appreciated.

Dell Vostro 3360, Core i5, 8GB RAM, 128GB SSD

hiberfil.sys is 6.6GB

You brought up another good point... IT DOES ONLY HAPPEN when it's been sleeping for an EXTENDED period of time. Not to the point where it would go into an AUTO-Hibernate but longer than just putting it to sleep then waking it back up.

Hi, I discovered the cause of my problem - Intel Rapid Start Technology (IRST).

Basically there is a hidden hibernation partition (different to hiberfil.sys) used by IRST.

The IRST is set to activate by default (on my system) after 120 minutes.

So after 2 hours of sleeping, drive activity would commence and the active user session in RAM would be written to the Hibernation Partition (8GB in my case).

The problem came during resume, when pressing the power button, it failed to restore the session from the SSD to the RAM, and I got a failed boot.

A second press cold booted the system to a fresh desktop with any unsaved work lost.

A workaround in my case was to disable IRST either in the bios or in the systray utility.

Ultimately the solution was a new motherboard, which was put in by Dell yesterday.

Sleep / IRST & Hibernate all work fine now.

Interestingly hiberfil.sys (6.6GB) is ONLY used for booting in this setup:

Sleep - RAM

Extended Sleep (IRST) - hibernation partition

Re-boot - is now (under windows 8 with 'fast startup' enabled) effectively a 'cold boot' ie read from disk

Shut down / PowerOn - is now effectively a 'warm boot' as it reads from hiberfil.sys

So there is some disk redundancy with the 2 systems (IRST and 'Windows Hibernate'), you could effectively utililize just one system with little difference in performance.

To be honest I am hard pressed to measure any difference in speed between any of the following:

1. a hiberfil.sys assisted boot
2. a IRST 'resume'
3. a Windows Hibernate resume

All of these are getting my system to a login prompt in about 6 secs from power button press.

At the moment I have all of them enabled, but may change to reclaim disk space.

Not sure most of that was relevant to you!

 Couple of other points:

S0 = on

S1, S2, S3 are various forms of sleep, depending on manufacturer, generally RAM is powered all else is off.

S4 is hibernate or IRST

S5 is off / shut down
