Chapter 4 Deleting a Password
4 Deleting a Password
If you forget the passwords you set up through WINBIOS Setup, the only way
you can restart the computer is to erase the system configuration information
where the passwords are stored. System configuration data is stored in CMOS
RAM, a type of memory that consumes very little power.
Erase Old Password
You can drain CMOS RAM power via J33 on the motherboard. J33 is a 2 – pin
berg that is normally always OPEN. Perform the following steps to erase the old
password.
Important
Make sure you are properly grounded before
performing the following procedure. You must be
certain that no electrostatic discharge (ESD) occurs.
ESD can ruin your motherboard. Wear an antistatic
wristband attached to a ground. See “Avoid Static
Electricity” on the following screen.
Step Action
1 Turn the computer power off and remove the computer
cover.
2 Place a shorting bridge on J33.
3 Turn on computer power for about 10 seconds.
4 Turn the computer off again.
5 Remove the shorting bridge from J33.
6 Turn on computer power again.
Since you drained power from CMOS RAM, all system
configuration information has been erased. You must now
re – enter the system configuration information by
running WINBIOS Setup.
