DFI Lanparty NF4 Ultra-D, Wake from USB keyboard not working?


N

Noozer

Any idea why my USB keyboard will not wake my DFI Lanparty NF4 Ultra D based
PC after I shut down Windows XP?

I've got the mainboard jumpers set to provide 5v Standby power to the USB
ports. BIOS is set to Wake on any keypress.

Keyboard is a Logitech Cordless.

You probably also need to tell BIOS that it should wake on the
USB's interrupt as well.

And you may need to check what is connected to your USB ports.
5 Volt stand-by is supposed to supply not more than 0.5 Amps in
total.
You have now jumpered 5 volt stand-by to provide USB power.
That means that you need to assure that power drawn by all USB
devices combined, in stand-by mode, if supported, remains lower
than 0.5 Amps.

Well, what exactly do you mean, when you write "shut down
Windows XP"?

Shutting down, is about powering off the system, putting it
into S5 power management mode, which to any lay person,
means it is "turned off", not asleep, so it can't be
awakened because it is off, not asleep. I am lax in all the
various power management abilities, but AFAIK, a system has
to be in S3, no higher, to "wake up" from a power
management event like keyboard.

It could be that you just need to check and change WinXP's
response to the shutdown sequence, that it sleeps instead of
shutting down.

The amout of current 5VSB can supply, varies based on the
specific PSU installed, and whether that PSU rating is
trustworthy. Even so, it is seldom that a system should
need more than 0.5amps of 5VSB. In other words, it would be
best not to jumper a lot of USB ports such that a lot of USB
devices were constantly powered when the system were off,
instead of only the port(s) needed/desirable to wake or
power up the system again. This could mean rearranging the
devices, which ports they are plugged into to restrain 5VSB
to only the port-pair that "needs" it. In general, any
parts that don't need to stay powered, shouldn't be.

I mean Shutdown. My Asus P4C800E-Dlx would wake from a Shutdown without any
problems IF I used a PS/2 keyboard. I've since upgraded and am using a USB
keyboard on my DFI based system.

Nope... A PC that has been Shutdown (not Sleep and not Hibernate) can be
woken.

I'll need to check into this... I'm pretty sure that I only switched over
the ports where the keyboard plugs in.

Yup.

Ok, but why would you assume a different system will do the
same thing... but not the same thing even, since it's not a
PS2 keyboard? Check your bios for such a setting and that
the USB port is jumpered to 5VSB.

We have a terminology difference.
If a system is shut down, it is not "woken", it is "turned
on". Woke/wake/etc is only from a sleep state.

Systems can be turned off from being off, S5 state.
It requires a setting in the bios to be correct, a compliant
device (if PCI card for example) and that the system is
supplying 5VSB, which for PS2 or USB, means the jumper would
need to be set to 5VSB instead of 5V.

Well that is a critical detail. That it is a keyboard is
not as important as what port it uses. That is not entirely
accurate though, some systems might depend on certain keys
to come on.

The BIOS settings between the two PC's are almost identical, as is the
jumpering for 5vSB.

I'm going to try a PS/2 keyboard once I dig it out of storage, also going to
try a USB->PS/2 adapter on this keyboard. Not the end of the world if I need
an adapter, but I'd like to know why the difference.

I agree... "Off" to me is the switch on the PSU turned off. As long as I can
turn the PC on using the front power button, I assume that I can also turn
on the PC from a "wake" event from a PCI card or properly jumpered USB or
PS/2 port.

Did you check Device Manager, Standard keyboard Properties, Power
Management tab?

Nope... but I have now. There is no power managment tab on either my
keyboard or mouse.

Thx!
