If none of the previous sections resolved your issue, we recommend you contact the computer manufacturer or motherboard manufacturer for the steps on clearing the computer password. Once the computer has booted, turn it off and then remove the screwdriver. If you've identified the solder beads, they can be jumped by placing a flat-head screwdriver over the two beads and leaving it on those beads while turning on the computer. The identification and location of these solder beads can vary and if not available in the computer documentation, is only obtainable through the computer manufacturer. They require the user to jump a pair of solder beads on a circuit board. Older computers, especially older laptops, don't have jumpers or DIP switches. It should be noted that many of these default passwords are for older motherboards and no longer work with newer machines. Locate and remove the CMOS battery from the motherboard for at least five minutes, then replace the battery and turn the computer back on. Removing the CMOS battery, like the one shown in the picture, causes the system to lose all CMOS settings, including the BIOS password. Once cleared, turn the computer off and return the jumper or DIP switch to its original position. Turn your machine on to verify that the password has bee reset. Once the appropriate jumper or DIP switch is located and toggled, the password should be cleared. (Laptops usually use DIP switches, not jumpers.)

It is usually located in a compartment such as the one containing memory. Under the keyboard or bottom of laptop - On a laptop, the DIP switch are under the keyboard or on the bottom of the laptop.By the processor - Some manufactures place the jumpers by the CPU of the computer.By the CMOS battery - Some manufactures place the jumper to clear the CMOS or BIOS password by the CMOS battery itself.Verify by looking at all visible edges of the motherboard.

On the edge of the motherboard - Most jumpers are on the side of the motherboard for easy accessibility.If you cannot find the password jumper, consult your motherboard's documentation by looking in the manual or downloading it from the manufacturer's website. It's important to realize that most motherboards have multiple different jumpers, so you need to make sure you're changing the correct jumper. The following list details the general locations for the CMOS jumper. What if I can't locate the CMOS password jumper? Some computers may also clear the password by keeping the jumper open (one or no pins covered). An example of the various jumper positions is shown in the image. To clear, remove the jumper from the two pins currently covered, and place it over the two remaining jumpers. This jumper is often labeled CLEAR, CLEAR CMOS, JCMOS1, CLR, CLRPWD, PASSWD, PASSWORD, PSWD or PWD. On the computer motherboard, locate the BIOS clear or password jumper or DIP switch and change its position. When working inside a computer, be sure you're aware of the potential damage that can be caused by ESD.
