 | Re: Sleep Return Timeout for Unattended Wake Up Nice to see such a time switch exists. I shut the lid on my laptop, it wakes up and new shuts down again. Or is this when you have set it to sleep after a certain idle time and that sleep is different. I have done all suggested in your excellent tutorials and still it wakes up. Microsoft help said he couldn't help me any more, except to refer me higher which would cost me money. Network adapter waking laptop from sleep?
The Optomize__Power document from Microsoft I found, he said only referred to sleep after idle, not when I shut the lid, which sounds silly to me. It says, | Quote: |  | | | Wake on Timer
Windows Vista systems are capable of waking from Sleep due to a timer event, such as a scheduled task or Windows Media Center television recording. The wake on timer feature enables the power manager to program the platform timer alarm to wake the system at a predetermined future time, based on requests from applications and services.
The global ability for the system to wake from timer is controlled in Windows Vista power policy. By default, the ability to wake from Sleep on timer is enabled for all power plans and both AC and DC power states. Friendly name Allow wake on timer
Description
Allow Windows to automatically wake your computer from sleep on a timer for scheduled tasks and other programs.
GUID
bd3b718a-0680-4d9d-8ab2-e1d2b4ac806d
Symbol
GUID_WAKE_ON_TIMER
Defined in
Ntpoapi.h
Balanced defaults
Enabled (AC)
Enabled (DC)
The Windows power manager programs the platform timer alarm when the system enters the Sleep state. Disabling wake on timer for DC power prevents the power manager from programming the platform timer alarm if the system is on DC power when the computer enters Sleep. Similarly, disabling wake on timer for AC power prevents the power manager from programming the platform timer alarm when the system is on AC power and enters a Sleep state.
Disabling wake on timer can help extend usable mobile PC battery life by preventing the system from automatically waking from Sleep and allowing the system to wake from Sleep only when the user is ready to interact with the system again. System manufacturers designing ultraportable laptops for business and productivity use may want to disable the wake on timer policy.
However, it is important to note that if wake on timer is disabled, the following Windows functionality are not available on the system: ·Hibernate idle time-out. ·Windows Media Center television recording. ·Scheduled tasks that are programmed to wake the computer from the Sleep state. ·Automatic checks for new Windows Update if the preconfigured time occurs when the system is in the Sleep state. ·Any other program or service that attempts to schedule a wakeable timer via the SetWaitableTimer API. | | | | | How do you disable this sucker, if it does apply to the sleep when you shut the lid? | My System Specs | | OS Vista Home Premium 32bit

From this and your other post, you might check your BIOS power management settings to see if it may also contain a "Wake on LAN" type option that needs to be disabled.
Hope this helps,

| | Administrator Vista x64 Ultimate SP2 Texas, USA | Re: Sleep Return Timeout for Unattended Wake Up I'm afraid that I do not know what else to try with your particular problem. Since it is related to the network waking up your laptop, you might post this question with all the details from both posts in the Network & Internet forum to see if someone may know of a solution for this for you.
I hope you get a solution soon,

 | Re: Sleep Return Timeout for Unattended Wake Up Well, after I re-enabled the "allow the computer to put this device to sleep to save power" on the USB hubs, which a Microsoft specialist working on this problem had disabled, it slept until I woke it up twice. Unfortunately, the third time it went to sleep but couldn't be awakened. Had to hit the power button to turn it off.
