A8N-SLI Fans keep on going on Stand-by (Q-Fan?)

[Dragoncarer]

I recently installed a new Maxtor DiamondMax10 HDD (250GB 16MB 7,200) on
SATA port 1 on my A8N-SLI.

I used to have a Seagate Barracuda on IDE port 1 (master). It's no longer
connected. My CD/DVD drives are now connected to IDE ports 1 and 2.

Since I've put the Maxtor in, the fans keep running in Stand By (*all* the
fans: CPU, GPU, 2x Case fans to CHA1 and, I think, CHA2). Previously, they
would turn off so that the computer was as quiet as if turned off, when
placed in Stand By.

I haven't changed any settings in BIOS as they relate to Q-Fan etc...

Any ideas on why this has happenned or how to 'fix' it, so that the fans
will turn off in Stand By?

I suspect it's because I'm using the SATA port...but...that doesn't seem to
make sense to me.

Many TIA.

Sleep states are controlled by ACPI and by how well the hardware and
drivers support ACPI. (Even a BIOS setting can throw it off.)

Microsoft has a DOS box tool called dumppo.exe

ftp://ftp.microsoft.com/products/oemtest/v1.1/wostest/tools/acpi/dumppo.exe

The "cap" option is supposed to give the ACPI capabilities. S3 is
suspend to RAM. I think S4 is hibernate (suspend to disk).

You could check the Event Viewer, and see if any errors are being
reported. Have a look through Device Manager, and see if anything
is funny looking in there.

When a computer goes into S1 standby, the power supply keeps running,
and the +12V is why the fans are still spinning. In S3, the
power supply goes off, and only +5VSB is still running. +5VSB is
what powers the DRAM while the computer is suspended to RAM in S3.
In S3, there should be no fans, as all main output voltages are off.

I've never heard of a disk doing this by itself.

HTH,
Paul

I just found out that if you allow any USB devices to bring the computer out
of standby (Power Management tab in the device's properties page of Device
Manager), then this seems to make the computer "run" in standby. I set this
up for my USB mouse and saw what you're seeing. My computer case was as
warm as if the computer had been running. Disabled that, and standby works
now. I haven't chased a reason for this, maybe someone else can explain.

You....are...................a................champion!

OMFG I can't believe that it works now! Thanks a billionty!!
I just disabled that option for my mouse and bingo!
I guess on my old installation of XP on the old HDD I had turned that option
off, or it had been turned off...straaaange.

Anyway, I'm so ecstatically happy right now.

Thanks for the help Paul, but I found out it was the wake-on-USB option for
my mouse that was allowing the fans to continue running...very strange. I
will never understand (some parts of) XP....
Thanks again anyway!

I'm curious what "dumppo" says in each state.

Does that mean you cannot wake your system with the mouse ?

Hang on I'll check now...no, the mouse definitely doesn't wake the computer
at all.

Just had a fiddle with dumppo for you...can't notice any differences between
wake-on and no wake-on.
Used dumppo cap, ps, admin, ac and dc commands and there was no difference.
Then again, I was using DOS from within XP, and I hadn't restarted between
each change.
However, the wake-on option is instantaneous, so I wouldn't have thought I
would need to restart...

The reason I asked, is I was curious whether dumppo can be used
to debug a problem like yours. Now I know it isn't any good for
diagnostics, but I'll still recommend it to people for forcing
S3 etc.
