Windows 7 hangs during sleep - delll e5400

Hi

 I upgraded a dell E5400 laptop to WIndows 7 professional. Sometimes when I enter sleep mode, the screen goes black like it should, but then the system hangs and never goes to sleep. After 10 minutes the computer powers off. When I turn it back on, I get the "windows did not shut down properly" screen and I choose to "start windows normally"

I used all the "official Dell" Drivers for Windows 7.

I don't see anything in Event Viewer that indicates a specific device is causing the SLeep to hang.

I ran Sigverif.exe. All of the "unsigned drivers" are related to my Printer (a brother MFC 8860DN, and I'm using their Windows 7 drivers) and "igfxress.dll" and "igfxtray.exe". Those are related to INtel Video, but again I'm using dell's "official" windows 7 drivers so I don't see why they should be causing the hang either.

Thanks for your help,
Matt

Is there a BIOS upgrade for your machine?  Sometimes proper support for ACPI requires a flash when new OSes are installed.

Check your network card and remove/unselect the "allow computer to turn off this device to save power".

Also try disabling Windows Image Acquisition (WIA) service. It tries to connect to Dell WebCam and there is some problem with that service from entering/resuming standby.

The solution that worked for me, when i had this issue was Changing the Sata Mode from IDE to AHCI in the bios.

Thanks for your suggestions. I'm still having issues with this. Here's what I've tried:

Updating to latest BIOS
Upgrading to latest Video Card Drivers
Disabling WIA service
Network card - remove/unselect the "allow computer to turn  off this device to save power".

Here's some more details: After I "sleep", the screen goes black but the power stays on with intermittent HD access. After about 10 minutes the machine completely powers off. Then in the BIOS POWER EVENT LOG there is a "power off event due to ACPI Power Management".

After reboot, Windows give me a   "Windows has recovered from an unexpected shutdown" error:

Problem signature:
  Problem Event Name:    BlueScreen
  OS Version:    6.1.7600.2.0.0.256.48
  Locale ID:    1033

Additional information about the problem:
  BCCode:    9f
  BCP1:    00000003
  BCP2:    85FDDB60
  BCP3:    82D3AAE0
  BCP4:    86B21008
  OS Version:    6_1_7600
  Service Pack:    0_0
  Product:    256_1

Files that help describe the problem:
  C:\Windows\Minidump\041610-27284-01.dmp
  C:\Users\XXXXX\AppData\Local\Temp\WER-53087-0.sysdata.xml

The only "unsigned" drivers on the system are  Printer drivers. I'm going to remove those next. Any other advice would be appreciated.

Set Power Management to have the PC "Hibernate" instead of "Sleep" aqnd  set Sleep to "Never".

I would settle for this, but the same thing happens when I try to "Hibernate". Screen fades to black, but lots of HD access and never any power off.

SATA is already set to AHCI

You don't have the symbols loaded, so your dump output is meaningless.

That BSOD error code points to "potentially" the printer driver.  It appears it cannot handle ACPI events and recover gracefully.

See if you can find WHQL drivers for it.

Do you have Power Management enabled in the BIOS and in Windows?
If yes, try disabling one of them. Using both of them can sometimes cause problems.

Coral47, "Do you have Power Management enabled in the BIOS and in Windows?"

I don't see anything in the BIOS explicitly related to "power management"... there are specific "WAKE ON LAN", "WAKE ON AC" options, but nothing like "ACPI on / off".

Furthermore, I don't know what "Power management enabled" looks like in Windows... I just know the "Power options" under control panel

I don't want to jinx it but I think I got it:

Apparently "Sigverif.exe" doesn't tell you about ALL the unsigned drivers on your system. My backup software, MACRIUM REFLECT, installed an unsigned driver. I discovered this when I went through device-by-device in Device Manger double-checking to make sure all drivers were up to date. When I got to my Hard Drive, I right-clicked, Properties, Driver tab, Driver Details. This showed me that there were 2 signed drivers and 1 unsigned driver from REFLECT.

I uninstalled REFLECT, rebooted, and now sleep works fine.

_Commented:
Sounds good.   : )

Just to answer you other inquiry, I have both BIOS and Windows Power Management disabled.
In the BIOS, if you ever see a seperate setting for ACPI, leave it Enabled or Windows Shutdown doesn't work right. Just turning off the different individual settings is enough.

>> ... the "Power options" under control panel

That's it.

So after a few days, the problem comes back. I guess it wasn't the backup software's unsigned driver.

I decided to take another look at the minidump it was generating. I gave up on this the first time because I couldn't get the Debugger enviroment setup properly to get the tool to work. This time I used the very thorough and helpful instructions here to setup the WinDbg debugger & environment. :

http://www.networkworld.com/news/2005/041105-windows-crash.html?page=1

After analyzing one of the minidumps, it looks like the sleep problem is due to "A Driver causing an inconsistent power state." (bingo!) and it's the Intel Wifi Adapter driver. Even though I have Dell's "windows 7" version of the driver, there is a slightly newer version of this driver on Intel's site.

I've installed the Intel Version and so far so good... the system sleeps like it should. I'll report in and award points when I've tested it a little more.

STILL working my way through this problem... system keeps locking up when going into sleep but ONLY after a couple hours of activity -- right after boot it sleeps fine -- makes this very difficult to troubleshoot.

I looked through some other minidumps which indicated the wired network card was problematic too and I've updated those drivers as well. So both drivers (wireless NIC and wired NIC) that are implicated in the minidumps are updated to their most recent Windows 7 versions. But I'm still getting sleep these lockups.

ANy other suggestions before I throw the computer out the window? ;) thank you

If I remember correctly there was a while ago a W7 bug
that produced similar results...

jcimarron, that's been my workaround so far, but I find the sleep feature very useful and would have liked to have kept it. but i think you're right and that's my only option at this point.

senad, any idea where I can read up more on the bug you are referring to?

I do this mainly to show you it is a common problem with lots of suggestions, but I do not think there is a "solution" yet.  Just the "workaround".
My Win7 PC had the problem when I first got it, but no more since I set Sleep and Hibernate to Never.

after months of trial and error, the issue was.... the antivirus! I  never thought that would be the culprit.

We use ESET Smart  Security 4 and it looks like there are issues with the latest version  and windows 7:

http://www.wilderssecurity.com/showthread.php?t=271195&highlight=sleep

Reverting  to an earlier version has fixed the problem.

my google-fu is  weak -- "windows 7 sleep eset" and the 2nd result is that thread  -- wish i would have tried that first :)
 
 Thanks for all your help! points all around...
