Turn PS2 port off on Asus P6T?

[TVeblen]

I've got that annoying problem where my optical PS2 mouse and keyboard stays
on when the system is shut down. Does anyone know if there is a jumper or
BIOS setting on an Asus P6T mainboard to turn the power off to the PS2 ports
when the system is off?
I have tried playing with the power settings in bios: choosing S3 config
makes no change. S1 and S3 is all this bios has for options.
My power settings in XP are set to Home/Desktop.

3 demerit points for any suggestions to use a USB mouse!

There should be a jumper to switch KB power between +5 and +5SB. Check
your motherboard manual.

Nope. I did RTFM, but there is nothing in there. I know there is USUALLY a
jumper for that, but damned if I can find it on this board. I got a jpg of
the board and scoured it at high res for anything not labeled in the manual
that could be the KB jumper. Nada.
So I'm looking for someone with this board that has actually accomplished
this task.

Try unchecking "Allow this device to bring the computer out of standby"
for your USB hub(s), mouse and PS/2 keyboard under Device Manager,
if you do not desire to wake the system via your USB, mouse and/or
PS/2 keyboard.

Check again for a jumper labeled either USB or PS/2 +5V/+5VSB.
You want it in the +5V position.

I looked again (12 times now?) and there are very few jumpers on this board:
OV_CPU, OV_QPT_DRAM, CHASSIS, and CLR_RTC. That's it.

I want the keyboard and mouse to bring the computer out of standby mode, so
I'm not willing to change that power setting.

Now I'm confused.. I think I need to read this thread from the
beginning. You either have standby power to a port or you don't,
and if you don't, there's no way it can wake up a system from
standby mode.

Disconnect all power from your PC. Use a multimeter to test for
continuity between your PS2 port's supply pin and the +5VSB pin in the
PSU connector.

Here are the pinouts:
http://pinouts.ru/Inputs/PS2Mouse_pinout.shtml
http://pinouts.ru/Power/atxpower_pinout.shtml (20-pin)
http://pinouts.ru/Power/atx_v2_pinout.shtml (24-pin)

If there is continuity, then either the PS2 port is hardwired to the
+5VSB rail, or there is a jumper or link on the motherboard. Probing
with your multimeter should find the jumper or link.

If there is no continuity, then the chipset must be switching +5VSB
power to the PS2 port.

I want the mouse to turn off when the computer is off - shut down - NOT in
standby mode.
It can, and should be ON - if the computer is in standby mode.
I've never had one where the mouse and keyboard stays on when the computer
is shut down (Off).
If I shut down the computer, then shut off the power supply switch to turn
off all system power, then turn it back on, the motherboard lights up but
the keyboard and mouse stay off.

Ah ok, and you're saying your system bios does not have a
mapping for the power button (i.e. POWER OFF = OFF/
STANDBY/RESET)?

I found a copy of the P6T manual. The option I referred to is first
on the APM Configuration screen. Make sure it's set to "Power Off",
and the others to "Disabled".

If that doesn't help, you might also try disabling USB Legacy support.
(This one's a longshot and probably won't fix the issue

Advanced menu/USB Configuration/Legacy USB Support = Disabled.

No joy. All settings are as you say. Legacy USB is no help either.
Thanks for taking the time to think about this. It's beginning to look more
and more like a "feature".

I'd be interested to hear what Asus' tech support says. I'm due for
a system upgrade pretty soon and was considering the P6T, but this
issue would be a deal breaker for me.

The post to asus tech support was sent earlier today. I'll post back here
later to tell you what they say. Might take a week.
Also- I just reset the bios power setting to S3 only. I'm going to see if
the setting works after a cold boot tomorrow.

The +5SB to the PS/2 port is switched. I have a P6T Dlx, and
use USB for mouse and keyboard, but connected the mouse
to the PS/2 port to see what happens. When the PSU is switched
on from AC off, the mouse has no power. When the front panel
On button is pressed to start the boot, the mouse becomes
powered on when it is enumerated by the BIOS. From then
on, the mouse is always powered, even after shut down, so
the +5SB connection to the PS/2 port is obviously latched
on, during first startup, and until AC is disconnected from the
PSU. The P6T only has a single, dual-purpose PS/2 port, so
it will take a mouse, or keyboard.

In legacy systems a keyboard attached to the computer was required to boot.
Is that still true of these new systems? Do the USB ports get enumerated by
the bios (so you can get into the bios immediately with a USB keyboard)? I
know I could test this out and find out, but I am more curios as to the how
and why this change was made.

Also this P6T board has 2 PS2 ports, color coded, for mouse AND keyboard.

No response from Asus. No way that I know of to stop the behavior. It is a
feature.
I would check to see if this is a common "feature" on other motherboard
manufacturers boards if you are shopping. But you won't see this listed on
any spec sheet. You will need to call and ask a human (good luck!).
Maybe we are being herded towards USB keyboards & mice the same way we are
being herded away from floppy disk drives. It would free up some prime real
estate in the motherboard layout!

Try Poweroff ???
http://users.telenet.be/jbosman/applications.html

"Poweroff is a small program for Win95/98/NT/W2K/XP to schedule a
shutdown/reboot/logoff/poweroff/Standby/Hibernate/Lock/Wake-On-LAN at
a certain time. I also support command line options that allows
poweroff to be used in batch scripts. It has a built-in scheduler, it
allows you to run a program before doing the action, you can give a
warning message to the user, wait for a process to finish before doing
the action and full remote control is supported."

Otherwise, have you tried looking for hidden BIOS settings?

For example, here is a BIOS report generated by AMIBCP.EXE for my old
socket 7 motherboard:
http://www.users.on.net/~fzabkar/M571/M571_V70.RPT

It lists all the BIOS modules and BIOS settings, including the hidden
ones.

There are different versions of AMIBCP for different chipset and CPU
classes, as denoted by the first two digits of the AMI BIOS ID.

I believe Award had a similar utility, but AFAIK Phoenix does not, or
at least it is not available on the Net. You might like to poke around
at http://www.wimsbios.com/index.jsp for more info.

Hey Frank. Good info but I'm afraid that BIOS editing is just way out of my
league. You just have to ask yourself: "how important is this issue" before
you go screwing with editing the BIOS. (Well how important is it... punk!).
I have a few power-off tasks scheduled for my PCs simply using Windows task
scheduler. Works great for my PVR machine.
If you have a link to a tutorial on editing the BIOS that any idiot could
understand, that would be of great help to me!
Thanks.

I have an MSI P45 Neo3-FR (601-7514-010) motherboard that behaves
exactly how you want. This is the first motherboard that I've
encountered that behaves this way, which I find it very annoying. When
I set in the Bios to wake the computer via PS/2 keyboard hot-key, I
expect it to work whether the motherboard is in S1, S3, or S5 state.

Here is my correspondence with MSI. They did confirm the behavior, so
it's pretty much a design decision.

End User 03/25/2009 Why does the motherboard turn off the PS/2
keyboard power when Windows is shut down? The front panel power switch
is the only way to turn the computer back on. When Windows is placed
in sleep mode, keyboard power is not lost, so the computer can be
awakened by keyboard hot-key. Wakeup event by BIOS or OS makes no
difference.

MSI Tech. 03/25/2009 Dear customer, only suspend mode will allow wake
up by PS2 event. When you shut down the system, all power will be
turned off including PS2 connections. Thank you.

Adventures in bios editing invariably end up the same way... RMAs
back to the manufacturer... This is especially true if the bios has
embedded RAID/SATA/etc controllers built into them.

The experts at the wimsbios.com forums may be able to edit the BIOS
for you. Editing involves turning on features that are already present
in the code -- it does not involve replacing the code modules,
although the latter can be done, too.

Anyway it might be worth checking to see if there are any hidden
options.
