i have a computer that is password protected but the computer has lost all keyboard function to log in. they have tried other keyboards and none work but all the keyboards work on other computers. any ideas?

its a gateway desktop with vista

hello scott, they're usb keyboards and she can't get into the bios

Looks like you may have to reset the BIOS to default, so the password will not be active,if you have exhausted every other possibility.

Take off the side panel and on the mobo you will see a small round CMOS battery.

You can either remove it (and replace,of course),or short the pins on either side-to achieve this.

It is just possible the battery may be flat -for example if the correct time and date isnt being displayed , this is likely.

The reason to get into the BIOS is to check whether the USB keyboard is enabled-under the heading "integrated peripherals" or similar.

If not enabled,will never work.

BIOS settings of this type shouldn't change for no reason,but everything is possible with computers.

Also check the USB controllers in Devices Manager to make sure they are correctly working

Sometimes just plugging into a different USB port to reset the pins may work.

Presumably the cable is OK.
