Getting exhausted trying to put my laptop to Sleep

Randysea · 10 Jan 2014

Sleep mode worked fine for 2+ years, until a month or so ago. I could get to Sleep mode from Start/Shut Down, or automatically by closing the lid. Now I can't get to it either way. Panasonic CF-W8 laptop running Windows 7 Ultimate. Sleep mode is essential when running on battery, and even preferable when plugged in and leaving the laptop for a few hours.

I know there are lots of threads about Sleep mode. I have tried all the standard and recommended approaches and more, and spent many hours on this. My power settings are correct for going into Sleep mode and unchanged. I have also tried changing them and then changing them back.

I have tried using Msconfig and eliminating every process and service that didn't look essential. I stopped the various speedup services like for Acrobat, MS Office, etc. I turned off Windows Indexing. Once in a while, for no repeatable reasons, I was able to get into sleep via Start/Shut Down, but never by shutting the lid. I tried starting up in Diagnostic mode but some video driver didn't load so I couldn't test that way. I tried starting in Safe mode but the power utility doesn't load, so there is no Sleep mode. Powercfg -Energy doesn't show anything new running that appears likely to prevent Sleep.

Also, it says S1, S3, and S4 sleep states are supported. I do not want to reformat and reinstall Windows 7 plus all my other programs from scratch. My last full system backup was after Sleep stopped working, so a restore from there wouldn't help. I am open to suggestions.

Here is some more info. It appears that the laptop will sometimes go into sleep mode based on timer settings. I have it set to sleep after 3 hours idling on power, 30 minutes idling on battery.

The Event log is a bit unclear on what is happening. There is one report of sleep based on "lid" but closing the lid has not seemed to get it into sleep mode. All it does is black out the screen. Other sleep events just say it went into sleep mode, without specifying which sleep mode (1, 2, or 4).

When my laptop is truly in sleep mode, the power light cycles slowly off and on and the machine cools off. If I close the lid the display will black out (I can see around the edges) but the laptop will stay warm.

One odd message I see occurs sometimes:
The driver \Driver\WSDPrintDevice for device urn:uuid:1c852a4d-b800-1f08-abcd-d89d67d8cc2d\UMB\3&250dc5ca&0&urn:uuid:1c852a4d-b800-1f08-abcd-d89d67d8cc2d/http://1c852a4d-b800-1f08-abcd-d89d67d8cc2d/PrintService stopped the power transition.

This looks like it might prevent sleep. However, it occurs sometimes before timer-caused sleep. One last thing: If I shut the lid, it seems to prevent the timer from causing sleep.

Just wondering - if you open your power plan and check the advanced power settings perhaps something is overriding a typical setting.

Brink is the expert on this, but until he sees this thread - try this:

Open Command Prompt (with admin rights) and paste : Powercfg -devicequery wake_armed and press Enter.

This will tell you what is preventing Sleep - In my case, it is usually a program that is downloading a file, etc.

Fantail thanks. I have checked settings. No help before. But I will try them again, maybe switch power choices.

PSCO2007 thanks also. Wake_armed lists nothing preventing sleep mode.

As for the link, I looked at most or all of the suggestions there before posting here. For example, the link to PC Won't Sleep was misnamed. It should have been "My PC goes into Sleep but immediately wakes up." Not my problem. Nonetheless, I followed the suggestion to try the Lastwake parameter to Powercfg. It acts as if my laptop did go into sleep mode. Here are two attempts:

_________________________________
C:\Windows\system32>powercfg lastwake
Wake History Count - 1 Wake History [0]
Wake Source Count - 1 Wake Source [0]
Type: Fixed Feature Power Button

C:\Windows\system32>powercfg lastwake
Wake History Count - 1

Wake Source Count - 1
Wake Source [0]
Type: Device Instance Path: ACPI\PNP0C0D\0

--------------------------------------------------

This is exactly what I'd expect to see if the machine had gone to sleep. But as I said, the power light isn't cycling and the machine doesn't cool down. It would do both if it were in Sleep mode. (Note, I don't know the difference between sleep mode 1 and 2, so I have no idea if there could be something in that difference affecting my machine.)

Still no solution. The workaround is to set the sleep timer to be very short when on battery, like 5 minutes idle. It is annoying but at least it gives me a sleep/standby option. I would still really like to find a solution for Start/ShutDown/Sleep and close lid not putting the machine into Sleep.

That's what I've been using... A power setting that makes the laptop sleep after 1 minute has elapsed. It's an additional click compared to using the "start menu Sleep", but not too bad.

When resuming normal operations, I switch to a different power management mode that waits 1hr or more before the laptop sleeps.

Yep, it's just a workaround... I realize this, but it's OK for me for now.
