Hello, how are you? I'm Steve. I upgraded my computer. The new board
has got a 24 pin ATX power connector. The other one had got a 20 pins
only.

Now, the power supply has an extra 4 pin cord which does plug to an 8
pin ATX connector sitting about above the top of the cpu. Could it be,
this power cord configuration, somehow, prevents ACPI S1 and S3 from
working properly?

ACPI specs are available here. If you have insomnia,
this will rapidly cure it. The spec is about the
size of "War and Peace" by Tolstoy.

http://www.acpi.info/

There is a little bit of info here as well.

"Advanced Configuration and Power Interface"
http://en.wikipedia.org/wiki/Acpi

ACPI is something that the BIOS plays a part in, as well as the
operating system. The BIOS passes "tables" at startup, to the OS. Some
of the "ACPI objects" take the place of Plug and Play
information. So, for example, the functionality of
a Soft Power button, may be indicated by an item in
the BIOS table.

The BIOS has some latitude, in terms of things like Standby.
For example, say the motherboard cannot properly handle
Suspend To RAM (S3). The BIOS could refuse to pass S3 as
an option, to the OS, and then if you attempted Standby
in the OS, it would just blank the monitor instead. So
if a hardware feature is "busted", the BIOS has a crude
way of preventing collateral damage.

Now, what does this have to do with the power supply ?
Virtually nothing.

Your ATX power supply has a main connector. It has 20 or 24 pins.
The extra pins on the 24 pin version, are redundant pins and
wires. They increase the maximum current flow that could be
safely handled by the wiring harness. No new functions are added
there.

The secondary connector, is the ATX12V connector. It powers
the processor, and ideally, is separate from the main harness.
It is typically a 2x2 connector on a desktop. Two wires are
yellow (+12V), and two wires are black (ground). If
you assumed the pins could handle 6A current each, the yellow wire
max current would be 12A. Multiply 12V by 12A and get 144W
max. If the Vcore (processor power conversion) is 90%
efficient, the net power delivered to the processor,
is about 130W. And that is just about the highest
power desktop processor.

For people who overclock, it is possible to set the clock
frequency so high, that the processor draws 200W+. Some
motherboards get so hot while doing that, that the area around
the CPU socket can melt foam plastic. In such extreme situations,
the other connector version comes in handy. That is the 2x4
connector. It has four yellow wires and four black wires, and
while the function is not changed, the amount of current
that can flow without burning any pins, is increased.

One difference between the old AT supply, and the new ATX,
is the ATX has "soft power" control. The PS_ON# signal, sent
from the motherboard to the power supply, indicates when the
motherboard wants the main power signals turned on. The
+5VSB power rail, is present while the computer is sleeping,
and is used for the logic driving PS_ON# as well. This
means the ATX power supply is split into two pieces, a
+5VSB chunk for standby power. And the rest of the rails,
switched on while the user is actually running the computer.

The rest of the functions (intelligence, if you will), is
the motherboard logic chips, and the OS and its ACPI code.

*******

To make ACPI work requires

1) ACPI compliant BIOS (able to "pass good tables").
2) BIOS table value passed, is able to indicate a working S3.
That is, if you want Suspend to RAM.
3) When WinXP is installed, a HAL is selected that supports ACPI.
Pressing F5 and selecting "Standard PC" would break it. The
OS installer would normally automatically notice the BIOS
supports ACPI, and install an ACPI HAL. A broken BIOS (I had
one), results in the wrong HAL being installed.
4) If Device Manager "Computer" entry properties indicates
"ACPI" in the name, then a good HAL (Hardware Abstraction Layer)
is present. If the user has just corrected an error in the
BIOS setting (for S3), then Microsoft "dumppo.exe" can be used
to attempt to correct the situation.

I expect there is a potential for some other issues, which
surround the presentation of options on the screen during
shutdown. But I don't know how that stuff works. For example,
sometimes an option will be grayed out, but I don't know
what thing in the registry might be responsible.

The purpose of all this Hardware Abstraction Layer stuff,
is to hide the details of doing stuff, from the OS. So
you may not find a piece of code in the OS, that
actually loads a register in the logic, and switches
off the power. It may actually be some BIOS code, with
the OS handing off control to the BIOS just about when
shutdown is to occur. That means, to some extent, the
OS works at a higher level. Otherwise, you'd "need a
driver", to make the soft power button stuff work.

For example, consider hibernation. On my computer, if
I hibernate (S4), the BIOS puts up a blue screen with
the word "Hibernate" at startup the next time. Apparently,
the BIOS has set some storage bit, so it knows that
hibernate was requested at last shutdown. The BIOS
is not clever enough, to go sniffing around for a
hiberfile (because the BIOS would have to know how
each OS in existence works). Instead, during shutdown,
the OS must be telling the BIOS, what state is to be used.
For S3, it would be told to maintain RAM contents.
For S4, it might set a bit indicating that
hibernation is currently in progress. But that
doesn't prevent the OS from also playing a part.
If the power fails, the BIOS hibernation bit is
cleared, the OS can still discover the hiberfile
is present, and load it instead of executing the
normal boot sequence. So this standard, does
appear to affect what the BIOS has to support.

So that is a bit of background (the bits I've learned,
without reading the ACPI spec :-) ).

Thanks Paul. what a great posting. I forgot to tell, my current power
supply has a 20 pin ATX plug and the previously mentioned 4 pin plug.
The computer won't start without the 4 pins plugged in, too. The heat
sink doesn't get hot, since the processor was without power. First I
was thinking it was broken, but was told it's not.

I assume there are power supplies which might only have a 24 pin
connector, which solely needs to be plugged to the mainboard, not the
the additional 4 pin plug.

As you have said, this was the way I have understand your reply, this
current power configuration can not be faulty, preventing the S1 or S3
state?

The BIOS lets me choose ACPI enabled or disabled (the computer won't
boot if ACPI was disabled, however ) as well as ACPI state S1 or S3,
which was set below ACPI enabled or disabled. The hardware manager
says ACPI Multiprocessor PC, therefore it should be fine and work
which it doesn't.

Would be great to save up some energy.

You need to have your 20 pin connector plugged into a 20-24 pin adapter
and then into the motherboard /and/ plug the 4 pin connector into the
socket you have already discovered for it. All should then work.
 
The power supply has 20 pin connector, the mainboard 24 pin. I don't
need to plug 24 in 20. Do you get it?

Steve
 
Sorry I think was a little brusque. But, I was tinkering with this a
while. so, should I get one of such adapter. Something new to the
collection of computer related stuff. : )

Steve
 
Ian said:
What you are doing is totally correct. The 24 pin motherboard
connector will accept a 20 pin PSU connector. Those 20 pin
PSU to 24 pin motherboard adapters are pointless. They don't
increase the overall current capacity. The important thing is
that you connect the 4 pin CPU 12 volt connector to the CPU
connector block. Later motherboards have an 8 pin CPU block,
but the 4 pin PSU connector will only fit into the proper side
of the block, the left side.

And yet I've had the situation where I plug the 20 pin plug into a 24
pin mobo socket and nothing. I then put the adapter in the middle and it
works - go figure.

The adapter is about two quid - hardly an earth shattering amount, just

To clarify this again.

1) The processor needs power. The processor power plug is separate.
The motherboard can have a 2x2 or a 2x4 power connector for the
ATX12V processor power. You *must* plug something in there, if you
expect the processor to work.

The 2x4 motherboard connector, can accept a 2x2 power supply cable.
Some motherboards cover the "extra" four holes in the connector
with a sticker, so the user will see which four pins to use for a
2x2.

Just remember - whatever you choose to connect to the processor
ATX12V connector, it must have an equal number of yellow and black
wires. Not any other colors!. Yellow is +12V. Black is ground.
The processor power source is 12V on modern motherboards.

2) If the motherboard has a 24 pin connector, it can accept a 20 pin
or a 24 pin power connector. The extra four pins that a 24 pin
has on it, use four different color wires.

http://www.playtool.com/pages/psuconnectors/connectors.html

This picture, shows a 20 pin power supply, plugged into a 24 pin.
Pin 1 lines up with pin 1.

http://www.playtool.com/pages/psuconnectors/20in24.jpg

The only time a true 24 pin power supply is essential, is if
the motherboard current consumption is expected to be relatively
high. An example would be an SLI or Crossfire motherboard, with
two PCI Express x16 video cards. If you used a video card like
a 6600 family card, where it draws 4 amps from the slot, two cards
is 8 amps, and the 24 pin connector that can supply 12A should be
used in that case. For many other, simple computer builds, where
there is only one video card, you can quite nicely survive with
a 20 pin power supply, plugged into the 24 pin motherboard.

The 24 pin power supply connector, has two 12V wires. At 6 amps
each, that means the harness can handle 12 amps without any
heat damage.

The 20 pin power supply connector, has one 12V wire. It can
carry 6 amps, using the single pin and yellow wire. If you had
a single 6600 family video card, that would draw 4 amps. The
motherboard fans might draw 0.5 amps through the three pin
fan headers. The total load might be approaching 5 amps or
so, whereas the limit for the pin itself is 6 amps. So the
20 pin connector works fine, with only one video card slot
load to handle.

Many modern, high power video cards (the ones for >$200),
have auxiliary power connectors on the end of the card.
The "slot power" component on those, could actually be
less than a 6600. The Xbitlabs.com web site, measures
video cards, which is where I get the "slot power" requirements
from.

(6600GT, ~48 watts flows through the slot connector. There is no
auxiliary connector on the card.)

http://www.xbitlabs.com/articles/video/display/gpu-consumption2006_7.html

This article on GTX280, a modern video card, gives more detail. The
overall power consumption is 178W.

http://www.xbitlabs.com/articles/video/display/geforce-gtx200-theory_12.html#sect0

In the detailed spread sheet, 23W of 12V power flows through the slot.
65W and 88W flow through the two auxiliary power connectors on the end
of the video card. So with this video card, the strain on the motherboard main
power connector is minimal. If you had two of these video cards
plugged into a motherboard, the total 46W from the two slots, could
easily be handled by a 20 pin connector. But the total power used
by the whole machine would be such, that an expensive power supply
would have been needed in any case, and the supply would have likely
come with 24 pins anyway.

Paul,

obeying to your post the ACPI configuration should work fine with a 20
pin only connector plugged in, which it doesn't.

Ian D,

I think I need to try an adapter. therefore it's a Taiwanese board and
since I downloaded driver from Jetway (the board manufacturer ) as
well as from AMD the chipset manufacturer.

I couldn't think of any other cause, at the moment. I would be pleased
if you had some other thoughts on the source of trouble.

ACPI is going to depend on the BIOS to some extent. What
is Jetway like, with regard to BIOS quality ? (We don't get a
lot of Jetway questions, so I don't know how to judge them.)

One way of cross-checking how Windows behaves with a piece of
hardware, is to see how Linux deals with it. Linux has its own
notion of ACPI, and the more public aspect of Linux discussions,
means you may learn more about the hardware you bought.

The motherboard side of things looks like a dead end. The downloaded
manual is 17 pages, and has no BIOS screens. I tried Googling, but
I'm not finding much that I can read. (Some hits in Germany and
Vietnam.)

Have you tried the "dumppo.exe" utility from Microsoft ? It runs
in a DOS window.

ftp://ftp.microsoft.com/products/Oemtest/v1.1/WOSTest/Tools/Acpi/dumppo.exe

dumppo.exe admin cap

The output looks like this. There is a claim, that dumppo
can also report if a driver is not ACPI compliant, but
I have yet to see any proof of that.

This thread, covers handling the case where the computer

doing, if everything else is correct to start with.
And without more evidence, I can't say whether that
is the case here or not. This only works for minor setup

If you're talking baout the 4 pin plug that goes to the 4/8 pin

AHA!

"System states supported.: S1 S4 S5"

The BIOS is saying perhaps, that S3 Suspend To RAM
is not stable ? There is no claimed support for S3
on your machine.

This is what was in the one I posted, which is from my
current machine. Now, most of the time, I can S3 Suspend
To RAM, but I have had the occasional issue with recovery
the next day (crash). I've switched to S4 (hibernate) instead.
So my BIOS says S3 works, when in fact it doesn't seem to be
completely reliable. All the other computers I have,
have perfectly working S3. This is the only one (VIA
chipset), that sucks.

"System states supported.: S1 S3 S4 S5"

And dumppo.exe cannot fix that, because the declaration
is coming from the BIOS.

If you want to investigate further, you'll need some other
environment to work in - I'm not aware of anything other
than dumppo, that displays that info. I tried Everest,
but it isn't there. Maybe a Linux LiveCD, and then some
Linux tool, can give a raw report of what the BIOS is
passing for ACPI tables.

HTH,

Hello, unfortunately dumppo.exe didn't work for me. I was trying to
set minsleep to S3 and maxsleep to S4, which was successful, but it
made the cpu fan stop spinning shortly after resume from hibernation.
Just like as it used to be. Both times the settings where still active
after reboot (my BIOS was yet missing the 'Suspend to RAM Enable/
Disable', but something seemingly was enabled ).

Also, minsleep=s4 and maxsleep=s4 was the same. Who knows?

A Jetway official, by the time being, told me they can't cope with the
issue. I replied whether or not he thinks it's about the 20 pin power
plug that I'm using. Let's see what the reply will be,

Therefore the fan stops from spinning completely, I assume there was a

Hello,

I ordered an ATX adapter, today. I'll see if the problem still does
persist once the other connectors got some juice as well.

I installed Speed Fan meanwhile, but after wake up the faults are
being effecting the operation of the PC, still. It's about the same.
