/ Bob Alexander <bob@ngi.it> was heard to say:
| do you have a double boot on that machine ? If so is the noise same
| also under the other OS ?

Interesting question. It can boot WinXP, but I haven't tried in...ages.

| Did you try muting all unnecessary audio ports ?

I think so.

| PCMCIAs like modem, eth or other nearby sources of EMF interference ?

No PCMCIA cards.=20

| Same noise with video backlight turned off.

Yep.

| Have got powernowd running ? Is noise same under all CPU frequencies ?

Uhm, no.

| Is the noiuse the same with the CD/DVD unit pulled outside ?

I haven't tried that.

| Is the noise same with the battery pulled out ?

I'll try a different batter.

| Did you try with another power source ? Plugged into a grounded outlet ?

The outlets are grounded, it's not limited to one outlet (or one power
cable, either.)

| An if all else fails, are you religious ? If so why not try with a
| priest blessing it ? :) :=3D) If you are not religious, did you get your
| hearing checked :)

I'm going to call those "last resorts" and look for other problems first :-)

Thanks for the suggestions.

                                        Be seeing you,
                                          norm
