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. J35 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.
