PC sleeps too soundly

[Jose]

This is wrong. I've had this argument before. Scheduled tasks can set a PME
(power management event) in the RTC (real time clock) that will bring the
machine out of hibernate. This occurs when you check the box labeled "Wake
the computer to run this task" on the settings tab of the Task Scheduler.
Wake On LAN can also be used to bring a machine out of hibernation. I do
both of these things regularly. Your hardware must support these mechanisms
in order to wake the machine.

Scheduled tasks use the real time clock (RTC) and power management events
(PMEs) provided by the Advanced Configuration and Power Interface (ACPI) to
wake the machine out of system standby or hibernate. On the settings tab of
a scheduled task, an option labeled "Wake the machine to run this task" will
set a PME inside the RTC for the time when the task is scheduled to run.

I Can't find the WOL reference but I do it every day.

It doesn't work for me from Hibernate on my ACPI system though and I
understand the use of the ST check box. It does work from Stand By.

Vista however, behaves differently that XP and there are a lot more
conditions/variables. The documentation specifically says it will
wake it from Hibernation but I think if is probably tied into the
hardware in some unspecified manner - it will come out of Hibernation
if all these stars are in alignment.

I see the Gigabyte MB can be configured to power up from the mouse,
but that has nothing to do with "coming out of hibernation" as we may
hear. It is powering up at a specific time or mouse click, not from a
ST.

The machine merely powers up and the XP decides what to do. It is an
interesting feature though - it would keep be from bending over to
turn on my machine.

In that case I would say that you have USB Power Management set so the
Computer may turn off the USB ports to save power. Go into Device
Manager, USB Properties and on the Power Management tab UNcheck that Option.

 

[Herzl Regev]

Sometimes it wakes up by the kbd and usually the Power On is needed.

 

[Herzl Regev]

It never goes into hibernation. Only Stand By.

My kbd and mouse are connected by the older plugs, not USB.

 

[Jose]

Sometimes it wakes up by the kbd and usually the Power On is needed.

If you are in Stand By, the mouse, keyboard or power can bring you out
of Stand By.

The mouse and keyboard have to be configured to do so.

You enable this feature on the Power Management tab of the Properties
settings for each device separately.in the Properties using Device
Manager.

To get into Device Manager, click Start, Run and in the bos enter:

devmgmt.msc

Click OK and set the mouse and keyboard Power Management Properties
settings appropriately - Allow this device to bring the computer out
of standby

Reboot and test.

There should not any "sometimes". It works or it doesn't work.

It never goes into hibernation. Only Stand By.

When you click Start, Turn Off Computer, you should see Stand By, Turn
Off Restart.

If your system is capable, when you press the Shift key, the Stand By
button will turn into a Hibernate button and you can click it.

If Stand By does not turn into Hibernate, check the Control Panel,
Power Options and make sure that on the Hibernate tab, the Enable
hibernation box is checked.

Sometimes there are some other things that need to be done to get
Hibernation to work.

Report your results if you still need help.

 

[Bob I]

I don't have anything that old to check, but you could look to see if
there are Power Management tabs in Device Manager for them.

 

[Herzl Regev]

My system shows less and less signs that hibernation is possible. I already
tried to send it into hibernation from Start->Turn Off Computer + Shift, and
it said that there are resources missing. After that, Start->Turn Off
Computer + Shift doesn't offer a hibernation button anymore. And in Control
Panel -> Power Options, I don't have a hibernate tab. In Power Schemes there
is no mention of hibernation, and it seems to me that earlier it was there.

Did it really say "there are resources missing" or did it say
"Insufficient System Resources Exist to Complete the API".

This was fixed in SP3 and you say you have SP2, right?

There is a hotfix for SP2 that might work if you don't want to
download and install SP3:

You can read about the reasons to upgrade to SP3 here and you can see
SP3 includes the hibernation hotfix 909095.

If you don't have a Hibernation option behind the Stand By button and
there is no Hibernate tab, sometimes that is indication of a need to
update video drivers.

If you need help figuring that out, do this:

Please provide additional information about your system:

Click Start, Run and in the box enter:

msinfo32

Click OK, and when the System Summary info appears, click Edit, Select
All, Copy and then paste the information back here.

There will be some personal information (like System Name and User
Name), and whatever appears to be private information to you, just
delete it from the pasted information.

For video driver information, expand the Components, click Display,
click Edit, Select All, Copy and then paste the information.

Not True, hibernate is a power off condition where the system state is
saved to the Hard drive prior to shutdown. There is no software running to
monitor keyboard or mouse inputs, as there is in standby. In Hibernate,
the monitor / screen, Hard drives and Processor are all powered down.

A PC in true Hibernate can only be woken from the power button.

Then you clearly don't know anything about what you are talking about.

There are many events that can be configured to awake a PC from hibernate.
One of the more obvious ones is the Windows own Media Centre if it is set up
to record a TV program from a TV tuner card. Many TV cards come with their
own applications that do a similar thing. Pcs can be configured to wake on
LAN events, keyboard events or even mouse events (but are hardware
dependant).

One of the infuriating faults that occurs with PCs is when some rogue
application sets up the PC to awaken from hibernation when you don't want it
to, and you can't figure out what it is.

One of my laptops regularly does this if I forget to disconnect the AC power
and remove the battery.

Shut down is the only way to make the PC such that starting it up can only
be accomplished by the power button.

 

[M.I.5¾]

But not the keyboard or mouse.

Including the keyboard and the mouse *but only if* the hardware supports it.
Most don't but some do.

 

[M.I.5¾]

Absolutely not true. How do you wake up a system if its power is off using
a mouse or keyboard?

Because Hibernate is not quite as powered down as you believe it to be.

Many things can awake a PC from hibernate.
