The mobo does not respond to keys pressed. The only thing that happens is that all the lights on the keyboard blink twice when I press any key and a kind of click comes from the computer, I guess from the speaker. It won't go into the BIOS, and if I have Windows boot up (from a pevious Windows installation) there also is no keyboard response. I replugged the keyboard many times with the same result. Clearing the CMOS does not help.

I tried an old keyboard I have lying around and it works normally. I tried the non-working keyboard with another computer and it works fine (as it always has up to now). If I return it to the ASUS A7N266VM, it still won't work.

I have never seen anything like this. Is this a known problem with this mobo? Anybody ever seen a similar problem? Anybody know what it is? I hope so.

If the good keyboard is USB, you might check pages 20 and 21 of the manual and see if setting KBPWR1, USBPWR01, USBPWR23 and USBPWR45 are all on pins 1-2. If the good keyboard is PS2, then I'm not sure what to try. You don't have a PS2 mouse plugged into the keyboard's PS2 port by accident, by any chance...?

Incidentally, what power supply are you using?

Thanks for the help

It's a PS2 plug. Both keyboards go to PS2. I could try switching the jumpers on KBPWR1. One side is supposed to be if you want to turn the computer on from the keyboard. Maybe the jumpers are labeled wrong. I believe one side uses the standby power line which stays on when the computer is apparently off. Its output is pretty limited. The green mobo LED is always on, as well as a yellow light by the LAN plug. (This mobo has every possible light, connector and gadget.)

No. But I tried the mouse connector (green) just in case. On that side the keyboard lights do not go on if I press a key.

>Incidentally, what power supply are you using?

An Antec 253, 250 Watt. Who knows; maybe the voltage is a little low for the nice keyboard? The same keyboard and PS worked together with another Athlon mobo before I switched to this one. I also had this same CPU in the other mobo until this mobo arrived.

I guess it has to be the power to the keyboard. What else can it be? It could be way the mobo handles the power to the keyboard or the actual PS. I guess it is worth trying another PS and/or the jumper.

Switching the jumper didn't help. I'll try another PS.

My impressions of this mobo:

Good mobo. I've had it running for most of two day with the ancient keyboard. Ran some torture tests. With the couple of games I tried, I'd say the graphics are significantly smoother than a Geforce2 MX I have with an ECS K7S5A, making this a far better value, except for the cost of DDR. I've got the in/out jacks set up for four speakers and the sound is nice (the instructions for how to do that are non-existant; you just stumble around till you find the settings. It can do also 6 speakers.) The MIDI sounds are very good. You can turn on reverb and chorus. The LAN works fine. I only wish it had some OC options, any. It has none at all as far as I can see. I know the CPU will OC to 150MHz FSB at stock voltage from trying it in another mobo.

There are no instructions for which "setup" to run in what directory of the CD. The autorun CD apparently iis set up for Windows ME. I ran all of the setups that were listed in the readme file for my mobo and XP. I think that may have been unnecessary. The setup under chipset/103 for XP seems to have actually done everything.

Later I got the 105 version at NVidia which is supposed to have everything in it. Unfortunately it locked up the first time I ran it. I ended up with a lot of yellow exclamation marks in Device Manager. After I uninstalled the NVidia drivers and reinstalled, the sound won't work. There is no volume control (mixer) installed, and I can't get XP to install one. Time to do a clean install of XP I guess.

I tried a different PS. No luck. To heck with the keyboard.

Looks like this will forever remain a mystery.
