Computer starts unexpectedly after shut down

[DLGolfs]

It seams that when I went to a wireless keyboard, I shut down , go to work
and then I return the computer is on. The keyboard does start up the
computer, but NO, I don't have a cat or dog or anyone home at the time.

Could it be a surge in the electircity? I have a surged protector and did
not have this problem when I had a wired USB keyboard.

I have remote access turned off, run adaware in the background and once a
day full scan as with AVG.
Any thoughts?

Are you truly shutting down or putting the machine in Hibernate or Standby
mode? (Sounds like the latter.)

Make sure that the wireless keyboard's receiver is not located anywhere near
something electrical (e.g., router; modem; desklamp).

DLGolfs,
I am assuming this event happens at any and different times
while you are away from your computer. In that case, while installing the
keyboard BIOS settings may, inadvertently, have been re-set. This is the
most likely cause of this behaviour. Go in to the BIOS setup program by
pressing F1, F2 or DEL, it should say on the screen just before Windows XP
begins to load which key to press to enter setup. Then look for the power
settings and a feature that controls what the system does after a break in
power. If set to ON then if there is a break in power (like your wife
unplugging the computer to do the hoovering then plugs it back in again)
then your computer will power up all on it's own - reset this value to
ALWAYS OFF. It also, just might be an auto-on at <time> feature in the same
place in the BIOS settings, but this is more unlikely. If, on the other
hand, the effect happens immediately after you try switching off. Then this
is because the computer is actually rebooting instead of turning itself off.

Surges are often hyped myths that rarely exist or are made
irrelevant by protection inside all computers. A restarting computer
is due to operation of its power supply controller. One input can be
defined in the BIOS. Certain peripherals can be enabled to signal
that power supply controller to power on. Disable those functions in
the BIOS.

Meanwhile, view numeric specs for that surge protector. Where does
it claim protection in numbers for each type of surge? Nothing exists
because it does not claim to protect from the typically destructive
surge. Fortunately, every computer already contains protection making
most surges irrelevant. Stick to facts and reality such as power on
functions enabled in the BIOS that permit some peripherals to restart
a computer.

When you say shutdown, does the power supply actually stop running?
No fans?

I suspect the BIOS - I knew one guy that found his computer waiting
for him every morning even after shutting down.

His BIOS was set to restart his computer at midnight - some default
value I guess. Sometimes they will wake on any key press, a LAN blip,
etc.

I don't remember about the PS fans though - good question. How are
yours when you shutdown? I want to know about that in particular just
for my own curiosity.

Check the Power settings in Control Panel also just to be sure it does
what you want when you shutdown (not hibernate or standby, etc.), but
suspect the BIOS. The motherboard has a battery you know... it could
be peeking when you think it is unconscious.

 

[DLGolfs]

I looked and don't have a setting for break in power or an auto on, I only
have power management and an enable and disable of the keyboard. I can have
the keyboard work on a specific key but does not give me an avenue to do
this, that is set the "specific" key.

any other suggestions?

I am definately not hiberating....

If the powerlight is still on then that can only mean that the computer
is in 'Standby' mode or Save-to-RAM (S3) sleep state. It is then just a
matter of finding the cause. Other than power management settings either in
the BIOS or Windows Power Management is where it's usually set.
If you can determine that it is absolutely non of the above causing
this, then other answers are somewhat limited. Some screensavers can put
your computer into 'sleep mode' and some other applications such as
third-party disk defragmenters can switch off your system. Take a look at
all your running applications (download and use process explorer for this
available free from Microsoft) to see if any running apps might be
configured to switch off your computer after a long operation.
If no legitimate application can be determined is using this then I
think you may assume that your computer is infected in some way. I advise
you, in that case, to do a complete scan with Antivirus software as soon as
possible.

Others also asked important questions. If not hibernating, which
other power down state is the machine in?

Rather unusual if your BIOS does not have 'power on hardware'
enable option.

Moving on to other problems: a power supply controller determines
how and when a computer orders its power supply on. If all those
other questions result in nothing, then time to start measuring
exactly what the power supply controller is doing. That will mean a
3.5 digit multimeter and 30 seconds.

First, answer the many questions from others - one question at a
time to hopefully avoid additional work.

 

[DLGolfs]

Yes, I thought it might be infected, have done safety live, trend micro and a
full adaware scan, nothing.

I use AVG now. I have had Norton but it missed a virus that Trend Micro
found so I stopped using it.

This all started when I started using the wireless keyboard, any thoughts?

The light is NOT on my sceen saver is windows and I have not changed this at
all. I guess I willl just have to cut the electricity when I leave. I did
this for about a week and it stopped but then after a few days started again.

I have already downloaded the windows based process software and nothing
there either.

Are there any processes that you know that will cause this, so I can stop it
or at least disable it.

I only use Windows to defrag, either in my system or through safety live.

It must be a spyware, I am going to run Spybot, I have Lavasoft running all
the time and a daily full scan.
If you have any other suggestions, please respond.

It must be a spyware, I am going to run Spybot, I have Lavasoft running all
the time and a daily full scan.

As noted previously, power up occurs due to actions of the power
supply controller. There is no malware in that hardware device. In
fact many other things also happen long before malware can execute in
the CPU.

The wireless keyboard means it connects how? USB? Infrared? And
your computer has not 'power on enables' in BIOS for infrared or USB?
Power startup is a hardware operation. Hardware switches are enabled
or disabled in BIOS to determine what the hardware does see and
responds to. But powering on a computer (by power switch or any other
means) is a hardware function completely inside the power supply
controller. No malware can exist in hardware.

If these 'enables' that cause power on do not exist (and that would
be unusual), then moving on to view what is causing this power using a
multimeter is the next step.

 

[DLGolfs]

ok, I undestand about the lack of malware in the hardware.
Keyboard is connected by USB wireless

I will have to look for 'power on" for USB, did not look there, others told
me to go to the power management.I did not look for USB ,
what should the USB be set at?

What is a multimeter?

So you think it is in the power supply? That is something is triggering the
power supply to startup?

 

[westom]

I will have to look for 'power on" for USB, did not look there, others told
me to go to the power management.I did not look for USB ,
what should the USB be set at?

You should be looking at every page in the BIOS. Relevant setting
may be anywhere - or where someone might guess it should be. Worse,
something that controls a power supply might exist in your system that
is not in other systems. Don't short your help of facts. View every
page. Report anything that might or imply power supply or power on
control.

Multimeter; also called voltmeter. Sold in most stores that also
sell hammers - ie Lowes, Tru-Value hardware, or Sears. Or in K-mart,
Radio Shack, and even some better convenience stores. Best price is
probably Wal-Mart for less than $18.

I don't think anything yet. That would be wild speculation.
Problems are not solved by speculation. Problems are solved by first
learning what exists. Fixing comes later.

In your case, a computer powers on when the power supply controller
orders it. So, what are inputs to that controller? 'Power on
enables' from various peripherals. Power switch. Various input
voltages. View all inputs. Only then analyze numbers and input
states. This is what they mean on CSI by "follow the evidence".

 

[DLGolfs]

Thanks for your information, however, beyond what I can comprehend at this
time. I have no idea how to use the voltmeter correctly and when I get the
results I will not be able to interpret them.
I guess I will just turn off the power when I leave for work.

I will look at the USB settings in the BIOS just to see if it is set
correctly. And I will look through the entire BIOS, for power information.

But, if the BIOS was not changed, then why all of a sudden I have a problem?

Maybe I missed the answer... When you perform your shutdown, is the
power supply (like the fan) still running?

There is a big difference between "power up" and "start windows". It
would be easy to start windows at a certain time or when something
happens if there is already power, but I do not see how anything is
going to be able to turn your power switch to the on position for you.

You do not need to get any kind of meter IMO, unless you just want
one.

If you think the problem started when you hooked up your wireless
keyboard, have you put your old one back for a while to see if the
problem goes away?

My friends computer was waiting for him every morning after he went to
bed. The BIOS was set (by default) to start Windows (or boot the
system) power up the system at 00:00 (midnight). He never physically
shut off his computer with a power switch (I don't either) but my
computer turns off everything - including the power supply when I shut
down, because that is the way I want it.

The BIOS settings can be a little hard to interpret regarding which
ones control such things. There was not an option that said "Start
Windows at HH:MM daily" or "Start Windows on keyboard input" - that
would be too obvious!

If you post your BIOS name, version, etc. maybe we can help you look
at the documentation online and see if it has such things. My old
BIOS has no such options, but I have some others that do.

Is your power supply running when you think your shutdown operation is
complete?

That is a very important question to answer first, then the info on
the BIOS and we can help you check through the options.

 

[westom]

Thanks for your information, however, beyond what I can comprehend at this
time. I have no idea how to use the voltmeter correctly and when I get the
results I will not be able to interpret them.
I guess I will just turn off the power when I leave for work.
...
But, if the BIOS was not changed, then why all of a sudden I have a problem?

If you cannot use a voltmeter, then never get near an Ipod or mobile
phone. Both are far more complex. It is that ridiculously simple.
So simple that both meters and hammers require the same skillset.

Why would you interpret anything? That is why you are here - to
learn. Move switch to 20 VDC. Touch probes to each colored wire.
Read numbers. Post number here. That is harder than using a
conventional telephone? Of course not. It is simpler. Stop worrying
about things that do not exist. If you are 13 years old, you can use
a meter. It is that difficult.

You changed an input device. BIOS settings previously would not
have an input device requesting computer power on. Now it does.
However that is also speculation. No questions can be answered
without those facts. You know what controls a power supply. We know
what all inputs are to the power supply controller. Without knowing
those inputs, then every question only results in speculation.

If you knew this stuff, you would not be here. You are here to
solve a problem which means learning some trivial and simple stuff.
Why post fear? Stop that nonsense. Read a number. Post it. Get a
useful answer without any more wild speculation. Appreciate how
simple this really was. As difficult as using a hammer. Also
appreciate why so many others did not know and therefore post
speculation.

First, what are all the options in the BIOS relevant to power and
peripherla devices (ie USB)?

It seams that when I went to a wireless keyboard, I shut down , go to work
and then I return the computer is on. The keyboard does start up the
computer, but NO, I don't have a cat or dog or anyone home at the time.

Could it be a surge in the electircity? I have a surged protector and did

I have remote access turned off, run adaware in the background and once a
day full scan as with AVG.
Any thoughts?

If you switch back to a non-wileless keyboard does the computer stay
OFF?

If yes, then the problem is wireless signal interference. The keyboard
could be defective, could be "noisy" as far as wireless signal, etc...

As many others have mentioned, taking you into the BIOS, unless you've
set it (even by accident) to restart after power outage, to restart at a
certain time, then you should not have any issues with the BIOS.

So, do the following:

1) check the BIOS, make sure that RESUME state is set to OFF.
2) disconnect the communication cable for the UPS.
3) reinstall a non-wireless keyboard and mouse.

When leaving, do a "Start", "Shutdown" and "Shutdown" do not to a
suspend and don't lets it "suspend" or "hibernate" itself.

Now, test, and determine which of the 3 items changes your situation.

You don't need a DVM to test this, there is nothing that wtom tells you
to check with a DVM that will resolve this.

Here is the big clue.

The OP says "the keyboard does start up the computer", so that must
mean than his BIOS is set to start the computer again on keyboard
input.

I am guessing (since he has not responded which would help) that after
he shuts Windows down, the power supply is still running. This would
be necessary to restart on keyboard input.

Given that the BIOS supports starting the computer on keyboard input,
it probably also can be set to start at a certain time (like my friend
was set to 00:00) and this feature is probably enabled, but who know
what time. Other conditions could also cause a restart, like a tickle
on the Ethernet port from a router, hub, switch, wireless...

If you can't figure it out by looking at the BIOS, tell us the BIOS
vendor, version, etc. and we can help you look through and interpret
the sometimes vague settings.

If you by a voltmeter, send it to me. You will not need it for this
problem.

 

[bud--]

Meanwhile, view numeric specs for that surge protector. Where does
it claim protection in numbers for each type of surge? Nothing exists
because it does not claim to protect from the typically destructive
surge.

Complete nonsense.

The major association of electrical engineers in the US (IEEE) says
plug-in suppressors are effective - very good guide to surge protection:
<http://www.mikeholt.com/files/PDF/LightningGuide_FINALpublishedversion_May051.pdf>

The US National Institute of Standards and Technology also says plug-in
suppressors are effective - another good but less technical guide:
<http://www.nist.gov/public_affairs/practiceguides/surgesfnl.pdf>


A surge as a cause is highly improbable.

L. - Did 't see your earlier post, but I already suggested the good
idea of putting the old keyboard back for a while and checking the
shutdown to be sure it wasn't hibernating or standying. I don't see a
reply, but it is pretty messy now.

The problem started with the new wireless keyboard and the machine is
set to start on keyboard input. No cats, dogs or hoovering.

If we knew all the facts, there my be hope even with the wireless
keyboard and set to start on keyboard input (like the manufacturers
WWW page).

Hmmm. Get an oscilloscope to go with your voltmeter.

set to start on keyboard input. No cats, dogs or hoovering.

If we knew all the facts, there my be hope even with the wireless
keyboard and set to start on keyboard input (like the manufacturers
WWW page).

Hmmm. Get an oscilloscope to go with your voltmeter.

LOL - that's why I started back at the top of the thread, taking what
was initially mentioned with the information from others comments. Wtom
always posts that people need a DVM to test their computer when any
basic set of diagnostic processes could locate the problem.

Since the problem started with the new keyboard then it's got to be a
BIOS setting to enable Suspend or Power-On and the background chatter of
the wireless keyboard is causing it to start.
