I took the plunge an finally updated my ancient 101 keyboard with a nice new
wireless with tons of functions.
I've been able to set it up to shut off with the "power key" but I'd also
like to power up using the keyboard. As it is,I still need to press the
power button on the case to start up or even wake up even though the
keyboard has Sleep/Wakeup buttons as well.
The Bios has lots of options for power managent.It's an NForce 4
ultra(wINFAST NF4UK8AA-8EKRS).I've been through the manual and done some
searching but I can't find this setting. So,can I do this?Thanks

It's easy to send a shutdown signal to Windows. I guess it's not so
easy to send a start up signal to the mainboard. A setting like that
would be in the BIOS. Look in your keyboard manual.

If there is no power to the keyboard when your system is shut down,
a signal can not originate from your keyboard, therefore you cannot
use the keyboard to start up your system.

Good luck.

Um ... Not sure it's possible with a wireless board.
The program to receive data from the keyboard has to be live ... and you
just shut the system down.

With a *wired* keyboard, there's a hardware connection and an interrupt
activated by keypress. In a wireless board, all that is emulated in
software. Shut off the software and ....

I could be wrong, of course.
I can imagine several ways a manufacturer *might* get around this.

Both motherboard and usb ir module are plugged into a surge protector that
stays on,I'm thinking that since both the USB ir module and the motherboard
are stll live after shutdown it would still be able to get a signal to the
motherboard.
If I press a key on the keyboard after I power down Windows I can see the
lights change on the wireless usb connector.
 
The first question is, is your keyboard receiver connected by USB
or PS/2 connection, or if by USB, is there a USB to PS/2 adapter
supplied? Usually there is a BIOS setting such as, Power on by
PS/2 Keyboard, in the power settings sub-menu. As long as
the computer is plugged in and the rear power supply switch
is on, the keyboard receiver will be powered by the 5 volt
standby power through the PS/2 connector. Special programmable
function keys will not be operational if the OS is not running, but
all the standard keys will work. The space bar is the key most
often used for system turn on. Also, there is usually a BIOS
option to use the mouse for system turn on.

I'm sure you've noticed by now, but Ian D provided the answer. I had
no idea. I used to go over BIOS settings on my prior mainboards
forwards and backwards (but not very much nowadays) and I don't recall
seeing that setting. I suspect it wasn't on older mainboards.
Whatever. Learn something new every day. I didn't test it, I just
looked to see whether it was actually there.

Have fun.

Doesn't do a damned bit of good, if the USB handling routines aren't
live on the computer.

Now you *might* try and see if your motherboard BIOS has an option
called "Wake on USB". If so, then there might be a way to get it to
work.

Well,the receiver has both a USB and a PS/2 connector. It came as a
keyboard/mouse set..I don't use the wireless mouse because It's cheap and
doesn't have enough buttons.Let's see what hapens.

I'm curious as to what scan code(s) the keyboard sends when you press
the Wakeup key.

This old DOS utility reports the scan code of each key:
http://www.users.on.net/~fzabkar/SCAN.COM

There will be two codes, one for make (key press), the second for
break (key release). Hitting the spacebar exits the program. Scan.com
can also be run in a Windows DOS box.

Alternatively, if yours is a Microsoft keyboard, then you can see the
scan codes using the mskey.exe diagnostic test which is included with
the Intellitype software.

Here are the codes for my Microsoft Wireless Desktop Elite PS2
keyboard, model 1011:
http://www.users.on.net/~fzabkar/MSKeyLog.TXT

In my case the Sleep key always produces these 3 pairs separated by a
1 second pause:

E0 5F <1 second pause> E0 59 <1 second pause> E0 DF

My BIOS has three options for "wake on keyboard" - disabled, "any
key", or "special key".

If I choose "disabled" or "special key", then the Sleep button works
as expected and no key will wake up the machine. OTOH, if I choose
"any key", then the machine goes to sleep but wakes up immediately. I
believe this is due to the 6-byte sleep sequence being interpreted as
an additional key.

As for what the "special" key is, I can only assume that its scan code
is as described in Microsoft's "Keyboard Scan Code Specification":

http://download.microsoft.com/download/1/6/1/161ba512-40e2-4cc9-843a-923143f3456c/scancode.doc

======================================================================
i8042-Based keyboards should deploy the following scan codes for power
management buttons, i.e., POWER and SLEEP buttons:

Power event
Set1: Make = E0, 5E Break = E0, DE
Set2: Make = E0, 37 Break = E0, F0, 37

Sleep event
Set1: Make = E0, 5F Break = E0, DF
Set2: Make = E0, 3F Break = E0, F0, 3F

Wake event

Set1: Make = E0, 63 Break = E0, E3
Set2: Make = E0, 5E Break = E0, F0, 5E
