Battery out is a good idea - but does it also have a "CLEAR_CMOS" jumper? this is a smallplastic cap that fits over two pins on the motherboard - normally right next to the battery.

Take the jumper off and place it on the next two pins (normally 3 pins altogether)

This should do it.

EDIT - have just looked online and there is a special jumper for this right next to the battery - its labelled PSWD. Same technique, remove jumper, put it on the other two pins, wait 5 seconds, replace on original 2 pins.

reset bios password on dell optiplex 320

go to Dell it will show you a picture on how to do it you just pull a small jumper plug off the bottom of your motherboard its very easy to do

see if you can find a cmos reset jump/switch on the motherboard.

if you if it just keep it in the reset pos of a few mins..if you still can't find it go to there web site and see if you can find a manuel for it..
