Hello,
old ibm thinkpad - turned on yesterday and all I got was blank screen except for 2 icons in the upper left corner - a screen and a padlock. no curser and a "beep" when I touch any key.
kids recently tried changing id and passwords. battery dead - running on a/c.
any ideas?
thanks, al

No this question was not answered this is IBM power on password. It is usualy last 4 digist of the serial no of the latptop. if that doesnt help you will need to bring it for guys to unlock it ;)
take it to the place that you got it from and exchane it better off doing that.! :)
