USB Power On with ACPI Power Management & S3 State


G

Guest

I was hoping somebody could explain and maybe solve an issue that I'm having
with my PC.

Initially, I had a Microsoft Internet Keyboard connected to a PS/2
connection on the back of my PC along with a Logitech MX700 Cordless mouse to
a USB connection. When my computer entered "standby mode" all system fans
would turn off and only my power light would remain on. I assume this is the
computer entering into an S3 Power Saving state. However, even though I had
both my keyboard and mouse set to "allow this device to bring the computer
out of standby," only my keyboard would actually resume the PC from standby.
The mouse never did.

Recently, I purchased a Microsoft Digital Media Pro Keyboard and connected
it along with the Logitech MX700 mouse to USB ports (so no PS/2 connection
this time). I noticed that when my computer entered standby now, all system
fans would remain on. I'm assuming this is the computer entering an S1 Power
Saving state. From this state, both the keyboard and mouse appear to be able
to resume the PC from standby.

Since I prefer the PC entering into S3 instead of S1, I manually tried
entering the PC into standby by clicking Start>Turn Off Computer>Standby.
This appeared to enter the computer into S3 mode (no fans on), but I could
not resume from my new USB keyboard or mouse.

I then decided to change some settings in BIOS... I changed ACPI Suspend
Type from S1&S3 to just S3 to see if that would change anything. When I
rebooted and checked the Device Manager, both the keyboard and mouse no
longer had a Power Management tab under device properties. Also, the
computer indeed entered Standby into an S3 state (i.e. no fans), but I could
not resume from either keyboard or mouse.

Now, this is where my main problem arises... I went back into BIOS and set
ACPI Suspend Type back to S1&S3. However, now when I try to enter Standby in
Windows it says "the device driver for the [Keyboard Name] device is
preventing the machine from entering standby." If I go under device manager
and uncheck "allow this device to bring the computer out of standby" and then
try and enter Standby, I get the same error except with the mouse this time
(i.e. the device driver for the [Mouse Name] device is preventing the machine
from entering standby."). Of course, when I uncheck "allow this device to
brin the computer out of standby" for the mouse, I can enter S3 mode then.

Any ideas why I was allowed to enter S3 mode before with my USB keyboard and
mouse but cannot do so anymore? The only change I made was in the BIOS to
ACPI Suspend Type to S1&S3 to just S3 and back.

BTW, I'm using Windows XP Professional X64 Edition... but the x64 newsgroup
appears to not be working.

Thanks.

Please remove the check marks for power management from both the keyboard
and the mouse. Reboot. Then try your S3 standby again. When in S3 standby
you must briefly press the power button to resume usage of the computer.

Thanks for the reply,

I realize your suggestion works... my issue was how to get into S3 while
power management was still checked on my USB keyboard and mouse. It had
entered S3 before the BIOS change with these settings checked and now it no
longer does.

The reason is because my motherboard apparently supports my USB devices
awaking my PC from an S3 state. However, if I can't get into an S3 mode
without unchecking my keyboard and mouse under power management, then it kind
of defeats the purpose.
