Before I installed Windows 7 Service Pack 1, my sleep mode was working fine with no problems. When SP1 was installed I could put the computer into sleep mode, but it wouldn?t wake up. It would also not wake up if the computer went into sleep mode as per the power settings of 20 minutes of non-usage.

I had to play around with the power options and came up with the following that appears to now be working:

Open control panel and go to

Power Options > change plan settings in the preferred plan options > Advanced Power Settings

+Sleep

Allow hybrid Sleep > OFF

Allow wake timers > enable

+USB

USB selective suspend > ENABLE

+Multimedia Settings

+When Sharing media [This is the critical one]

Set to allow the computer to sleep.

Click apply and ok and that should do it.

It worked for me I hope it works for you.

Ok just set up my power plan as guided..... fingers crossed this works, before doing this, I would get full fan speeds only, and no waking up when I tried.

Here goes...

EDIT - I guess the fact I just had to turn the PSU off at the back because the power buttons didn't work and the system fans were at full speed shows this didn't fix it for me

Just wanted to bump this and mention that I had the same problem, and the suggestion to disable hybrid sleep is what fixed it. As a bonus, the system also goes into sleep MUCH faster.

I never needed hybrid sleep anyway, it was just a default. Thanks for the tip!

This actually happens to me, before SP1 my PC use to be able to go to sleep and return from sleep. After SP1 it may go to sleep but everything is still wuring and the monitors just turn off (you have to hold down the power button to turn it off).

I will try this when I get home, thanks!

My sleep works the same as it did pre-SP1...I hate when the computer wakes up automatically because of scheduled tasks (namely Window Media Center update related). Granted it does go back to sleep when it's done (usually around 4-5 minutes).

got same issue but the above is not fixing it for me, now considering uninstalling SP1, as the machine in question is a media center operated from an armchair, i'm way too lazy to get up, open a cupboard and push the power button to wake my machine

anyone any other ideas?

Just wanted to say that for me and many other people, the above mentioned solution did not work.

It turns out that for many users, the problem is actually a compatibility issue between Internet Explorer 9, and Skype versions 5+.

Problem: After installing Windows 7 SP1, entering sleep/hibernate mode causes PC to hang for an extended period, and then bluescreen.

I tried all of the following, and NOTHING worked:

- Installed Win7 Hotfix KB2495523

- Disabled "Allow hybrid sleep" in power options

- Installed newest version of real-tek ethernet driver

- Disabled "Allow Wake Timers" in power options

- Set JavaScript Timer Frequency -> Maximum Power Savings in IE power options

SOLUTION

There are currently 2 solutions:

1. Uninstall Skype v5, and roll back to version 4. (Version 4.2.0.187 confirmed working)

or

2. Uninstall Internet Explorer 9 (Windows Update --> Installed Updates --> IE9, Uninstall)

Skype Bug Report: https://jira.skype.com/browse/SCW-2796

NOTE:

Another option is to simply close Skype before entering sleep mode.

Confirmed that the newest version of Skype that does not lead to the crash when IE9 is installed is Version 5.0.0.156. Reverting back to 5.0.0.156 fixes the issue.

I think my issue stems from when Windows tries to switch automatically from sleep mode to hibernate mode. My power light is steady/on (it blinks when it's in sleep mode), the fan is running, but whenever I try to do something, it just sits there.

It would also not wake up if the computer went into sleep mode as per the power settings of 20 minutes of non-usage.

On my Toshiba Satellite L655D-S5050, not only did SP 1 make it impossible to put the computer to sleep, or hibernate, but when it shut off I couldn't get it to wake up. There were not even any indicator lights on the front panel when plugged into the power supply. I finally figured out that if I disconnected the power supply, removed the battery, then re-connected the power supply, I could get it to come back to life. I was so relieved to get the computer to come back to life, that I didn't want to even try to get it to work with SP1 that I simply uninstalled SP 1. I saw no particular benefit, only problems, so I'll live without it until the good people at Microsoft re-issue it without the rather serious bugs. I looked for a solution with Toshiba, but, typically, there was none.

      If you don't care to read what I said, then you prove my point. Maybe written media is beyond your attention span. Titles are not summaries my friend.

      Nobody asked... in fact, I said "I don't care about political leanings"

      TLDR. Here is a far better title (just a basic example): Windows 11 26H2 to allow disabling Web search results

      There is nothing wrong with this title. You have completely missed the plot when it comes to "clickbait." The issue was never that a title tries to entice you to click, that is how titles have worked for over 100 years. The issue is when the title subverts expectations, getting you to click expecting something that isn't there. The classic clickbait example is "Boyfriend caught cheating, what happens next will shock you," then what happened next is the girlfriend was upset...which is probably the least shocking outcome imaginable. If sounds like what you want is for the titles to be a collection of 10-word summaries that you can skim, get the just of the story, and only click if you want more details. That is not, never has been, and never will be what titles are. You can go all the way back to print newspapers during the great depression and see the same thing. The newspaper was locked in a vending machine, all you can see is the headline, you choose to put in 5¢ to buy the paper and read the rest if you want. Those headlines were written in a way to sell the paper, not just to provide a summery. Here are two actual headlines from that time, "Wall Street Lays an Egg," or "Stocks Hit Bottom?" Maybe you'd say something like "it was wrong then and it's still wrong now." Okay, fine opinion to have, but it isn't like Neowin is doing something unjurnalistic, they are just following the age-old standards for written media.
