PC turns itself on while hibernating

[Guest Joe]

I have a Compaq Presario sr2044nx PC with XP MCE2005, Service pack 2, 2.8ghz

Pentium D, 2GB ram, 180GB HDD, 90 GB free, that turns itself on while it's

supposed to be hibernating. Some days it stays off, sometimes it is only off

for an hour. I have to turn off the power strip if I want to be certain it

will stay off.

 

The Microsoft hibernate patch KB909095 is installed, and automatic updates

are turned on. In Device Manager, there are four devices - network card,

modem, keyboard, mouse - with a "power management" tab which have a checkbox

for "allow this device to bring computer out of standby," which are all

unchecked. There are no options in the BIOS for waking up that I can find.

I use AVG antivirus and Nero BackItUp for backups that I have scheduled for

Saturdays. When I first got the pc, it turned itself on, but it turned out

that the network card was waking it up because the checkbox I mentioned was

checked. Unchecking it solved the problem for about a year. It's been doing

this for a few months now and I'd love to get this resolved.

 

I've searched for answers and found nothing useful so I apologize if this

has been covered already. I understand that there's a tool in Vista which

shows the event that woke up the system. Is there such a tool for XP? If

it's a program running that schedules something, how do I determine which one

it is?

RE: PC turns itself on while hibernating

 

in your bios there should be an option to Wake on ring, which wakes your pc

whenever your phone rings, or wake on lan, which wakes your pc for incoming

lan acitivity.

Do you have any scheduled events in Task Manager with the option enabled

to power up the computer? I haven't used Nero BackItUp so I don't know

what options you can configure for its scheduled backup job, like having

it power up the computer.

 

Are you actually powering off the computer or just putting it into

standby mode? Power options in Windows might configure the Power button

(on the case) to merely put the host in standby mode (and you have to

press and hold it in for 4 seconds to actually power off). You would

have to shutdown Windows and then during the reboot for the POST but

before Windows loaded you would then press and hold for 4 seconds to

actually power off. Check your Power Options applet in Control Panel.

I've even seen some pre-builts (don't remember if it was Compaq or Dell)

where the front Power button would never power down the host but merely

put it into low-power mode. You had to reach behind to flip the switch

on the backside of the case to actually remove power.

RE: PC turns itself on while hibernating

 

The only option in my BIOS in the "power" section relating to wake is "wake

on lan in s4" and it's disabled. There is no wake on ring, but the modem

isn't even plugged in to a phone line so I don't think that's an issue.

Re: PC turns itself on while hibernating

 

The only task in the "scheduled tasks" control panel is an HP printer task

that is not set to wake the pc, but I deleted it just to be safe. The

software for this HP printer is horrendous so I don't mind getting rid of it.

 

 

Nero BackItUp doesn't have any wake options that I can find. And I have my

power management set so that the computer will hibernate when I press the

power button. It hibernates and then powers off like it's supposed to, it

just won't stay off. I also don't think it's a flaky power button because it

never turns itself *off*.

Are you using a wireless keyboard and/or mouse? If so, disconnect the

transceiver from the PS/2 or USB port and test if the host remains in

power saving mode. If that works, select a different channel or code,

or push the reset button on the mouse or keyboard and then the reset

button in the transceiver to do a resync between them. For an optical

mouse, make sure there is no bright light shining at the mouse to cause

an extreme change in ambient light level. Toss a handcloth or unplug it

during a test to see if the host then comes out of hibernate mode.

 

In your BIOS for the ACPI power option, check if S1 or S3 mode is

selected. S1/Sleep/Power-OnSuspend is where the system appears to be

off, disks are stopped, CPU is stopped but not unpowered so it retains

its context, but RAM gets refreshed to retain its context, and the

system is really running in a low-power mode. S2/Sleep mode is an even

lower power mode than S1 (CPU is unpowered rather than just stopped) but

RAM still gets refreshed. S3/Standby/SuspendToRAM is the typical

Standby mode where the CPU is unpowered so it loses its context, RAM is

in slow refresh mode (to retain its context), and the PSU is in

low-power mode. S4/Hibernate is not completely off but still a

low-power mode where RAM gets copied to a file on the hard disk and the

hardware is completely off. You can still resume from hibernate mode

from events in the BIOS. S5/Off is full power-off mode, nothing is

saved, and requires a cold restart to load the OS.

 

For your host to be coming back alive, it doesn't look like a device is

awakening the host or it never gets into S4 hibernate mode but instead

just S3 standby mode. It takes time to copy the RAM into a disk file.

When you press the Power button, does the host go immediately into a

low-power mode or is there a flurry of disk activity for awhile (for the

RAM to disk copying)? Going into Standby mode takes a few seconds.

Going into Hibernate mode can take several minutes depending on how much

memory has to be copied (it all gets copied, not just the inuse pages).

4GB would take longer to write the disk file than 0.5GB. If you were to

copy use a batch file to continually write 4K blocks into a disk file,

how long does that take? When I'd take my work laptop to home, it took

a lot longer to go into hibernate mode than standby mode, so much so

that after awhile I decided just to put it into Standby mode to take it

home. If you're only getting into S3 standby mode, maybe Windows Update

is waking your host. Do you have WU set to NOT update unless you start

it manually?

 

Just because the video goes blank, the hard disks stop spinning, and the

system seems to be off doesn't mean you actually got into hibernate

mode. Something interferes with implementing hibernate mode so all you

really get is standby mode. Sometimes you get a warning that you can't

go into hibernate mode but you might only get one warning. Incompatible

devices (those that won't hibernate) or drivers can prevent getting into

S4/hibernate mode. However, that usually means you can't get INTO

hibernate mode, not that you would randomly come out of it. That's why

I wonder if you really ever do get into hibernate mode and might only be

in standby mode where a bright light flashing on an optical mouse,

someone jarring your mouse or tapping a key, or someone also with a

wireless mouse using the same channel or code as yourself isn't trigging

your system to come out of standby mode.

 

And now for the truly weird source: the Power button. We had a host

with a broken button. It seemed to pop in/out like normal but actually

it wasn't coming all the way out. A forklift rumbling down the hall,

someone slamming the lab door, or pounding on the desk on which the host

sat could make it power up. The vibration caused a momentary short in

the switch to the 2-pin PwrOn header got shorted to tell the mobo to

tell the PSU to power up. Manager didn't like my hackjob idea of

putting in a new but separate switch so instead we gutted the host to

put its parts into a new case.

 

By the way, the same instructions in Vista about using powercfg.exe also

applies in Windows XP. Run "powercfg.exe /?" in a DOS shell to see how

to use it. Mentioned this just in case you thought powercfg was just a

Vista thing.

Re: PC turns itself on while hibernating

 

A mouse movement cannot bring a computer out of 'hibernation'. Power is off

when hibernating.

If 'wake on lan' is off and nothing scheduled the problem could be a

defective power supply or some such thing as a poor ground connection.

Re: PC turns itself on while hibernating

 

Then I'll try shutting it down for a few nights instead of hibernating and

see if it stays off. If so, I have hibernate issues that I want to resolve

and I'll post back. If it doesn't stay off, then I guess I have a hardware

issue and I'll just deal with it. I appreciate the input. Thanks.

Assuming the OP is actually getting into hibernation mode. The OP needs

to see if going into hibernation mode actually works. Maybe he's just

going into standby mode.

Re: PC turns itself on while hibernating

 

Power on lite stays on if in standby.

Check in the bios for wake on lan, wake on modem, etc. Also, a vibration

that moves the mouse can wake the pc up, so can a cat on your keyboard.

Re: PC turns itself on while hibernating

 

It is definitely hibernating. The screen shows the hibernating progress

indicator and when it's full the power cuts off completely. I can turn off

the power strip and upon turning it back on and pressing the power button, it

goes through the POST, then shows the 'resuming windows' progress indicator.

There is no doubt that it's hibernating as opposed to standby. I hope that

clarifies it.

Then I'd say to replace the CMOS battery. It's less than a $5 fix.

This ensures that what is in the CMOS table (a copy of the factory BIOS

settings along with your modifications) remains there, doesn't get

corrupted, and eliminates timer problems. The most common one is a

wafer battery, model CR-2032. BestBuy, Walmart, Target, BatteriesPlus,

and lots of places have that one (but sometimes are out of stock because

it is common for many other uses).

 

How old is this computer? The battery needs to get replaced at or

before 5 years, sometimes 3 years if the battery was already a couple

years old when installed. Hmm, come to think of, it's time to replace

my CMOS battery in my 6-year old host.

 

Another possibility is an old PSU that eventually gets too much ripple

voltage which can confuse the Pwr-On signal to the motherboard. Even

when you think the computer is fully powered off, the PSU supplies

+5VSTBY (5 volts standby) to the motherboard to power the power-on

circuitry. The power switch used to go to the PSU in the old AT-style

systems. ATX-style systems have the power switch go to a 2-pin header

on the motherboard where circuitry (that needs to be powered) will tell

the PSU when to fully power up. (That's why I mentioned the weird

problem with vibration and a bad Power switch in my other post.) The

only way to completely remove power inside the computer case is to yank

the power cord (so power isn't even getting into the PSU), and that's

what you are doing with the powerstrip.

RE: PC turns itself on while hibernating

 

I think I found the issue - the tv guide in media center was set to download

automatically and I believe that was waking the pc. I found it by looking in

the event viewer and noticed a bunch of messages relating to the media center

guide around midnight on various nights. Once I disabled the guide, the pc

quit turning itself on. It's only turned itself on a couple times in the

last month, for whatever reason, and I can live with that.
