Turn the unit off. If you open the unit there will be a jumper to clear the CMOS and a battery. Remove the battery and then switch the jumper as silkscreened on the board. usually there are 3 pins currently crossed are 1 and 2. switch it to 2 and 3, press the power button then hold for a few seconds. unpress the button and remove the pwoer cord. press and hold the power button again for a few seconds to clear all power. reconnect the jumper to 1 and 2. put battery in and plug and boot. password should be gone.
in some units there is a "clear password" or "cmos password" jumper. crossing this will remove the password in those units.
