Bugsy, just in case-have you tried without a password? By pressing and holding down the power button 5+ secs will power down the machine. Removing the battery will shut it down too. The issue is "will you still be locked out when you reboot?" You should try starting in safemode when you reboot (pressing F8) during the initial boot process and see if you can log in as administrator(no password). If you can access safemode try to reset the administrators password in user accounts. Let me know if you've made any progress. Tim
