Laptop taking too long to sleep.
My Samsung laptop brought couple months back keeps taking a long time to sleep. The actual time taken seems to vary greatly, sometimes a few seconds, but otherwise hours upon hours (I at that point shut it down).
The time it takes for it to sleep does not seem to always correlate to the numbers of applications I have open either, nor the RAM usage. Sometimes it sleeps fine with a lot of programs open, other times it fails to when there are only a few.
I have looked around the forum, but cannot find an answer. Please help.

Here are some commands you can run from an ELEVATED Command prompt that might help.
powercfg -devicequery wake_armed
powercfg /? is the MS HELP for the other commands i suggested (and more).
If you get anything back from powercfg commands you need help with, post back with screen prints showing the results.
I noticed you have a BSOD thread for sleep issues.
Maybe you should post a comment in that thread about this issue including a link to this thread?
Someone that helped with that issue might be able to help with this.
In my experience:
Windows sleep and hibernate are awesome when they work correctly.
If there are issues, it can be a never ending nightmare trying to find the cause and fix.
It seems there are too many factors that can affect sleep and no-one including MS has fully documented or understands all of it.
- Bad driver, usually video
- Unsaved Windows theme
- BIOS settings, and maybe BIOS version
- Devices that can wake the PC
- Programs that can wake the PC
- Scheduled Tasks that can wake the PC
- Wireless mice
- yadda, yadda, ...
I just noticed and tried the "wake_from_any" powercfg option with this command:
powercfg -devicequery wake_from_any
I've never used this to resolve issues i worked on, but maybe this can help you, or add more confusion!
I can't remember ever seeing this option suggested in any threads i found looking for help trying to fix sleep issues.
Right now I find it interesting (and confusing), but it might be something that can help anyone having sleep issues...

Sorry, I don't understand, what do you mean by elevated command prompt? Does that just mean run as Administrator?
Anyways, powercfg -requests returned:
powercfg -energy said:
Energy efficiency problems were found.
See C:\windows\system32\energy-report.html for more details.
The file is attached. Would be great if you can take a look.
Also, yeah, my computer has had problems with BSOD before, owing to the network driver. I have also had some troubles with the Video driver, so that might be the cause you mentioned. I will post a link to this thread like you said.
Thanks for the help!

Think it is attached this time .
Found something interesting though: Today I took my computer to school, and it sleeps almost instantly every time. When I got home, and have it plugged in, it starts being inconsistent again. This may be a coincident though, as this is an inconsistent problem to begin with.
Edit: Hmm, this must be why. Html files can't be uploaded here. Is there any way I can put it here then?
The errors are:
Power Policy:802.11 Radio Power Policy is Maximum Performance (On Battery)
The current power policy for 802.11-compatible wireless network adapters is not configured to use low-power modes.
CPU Utilization:Processor utilization is high
The average processor utilization during the trace was high. The system will consume less power when the average processor utilization is very low. Review processor utilization for individual processes to determine which applications and services contribute the most to total processor utilization.
Average Utilization (%) 9.04

Recycling a movie from my harddrive is taking long long time.
Why is this. Like 10 minutes plus and it still says recycling. It should only take a second. Is it bad to let it continue at its own pace or should I restart the PC and try it again?
Laptop takes a long time to sleep
When I place my laptop into sleep (either from the button or closing the lid), the screen goes dark and then it basically locks up. If it's on battery the battery will last a short time (as if it was on) and then it dies. Typically, if it's on AC, I end up having to hold down the power button...
