A method you can try if you don't have a password reset software is by removing the CMOS battery. Remove the CMOS battery then turn the computer on. The system BIOS will be reset and password will be removed. Then you can put the battery back in. Click on this link for the Gateway ML6230 Notebook PC Manual. Check page 36 for CMOS battery removal instructions.

Method.

When your Gateway computer is switched off, it still keeps track of various system information such as the date and time, thanks to a small battery that never powers off. The size and thickness of a dime, the CMOS battery can run out and need to be replaced. You can swap out a dead CMOS battery with a new one by removing the Gateway computer's side access panel.

• Phillips-head screwdriver
  

• CMOS battery replacement

   Shut down the computer. Remove the power cable from the back of the computer case. Disconnect the cables for the monitor, mouse, keyboard, and printer.

The CMOS battery is located on the motherboard, just under the bottom left side of the keyboard, by the letter 'V". It looks like a clock battery, marked 3V (volts). The battery comes out of its "cage/connector" by gently lifting it with a small flat screwdriver. Replacement CMOS batteries are inexpensive and readily available at any computer shop.
