You can set the jumper as follows:

Clearing the BIOS settings
CAUTION: Do not change any jumper setting while the computer is on. Damage to the motherboard can result.
This motherboard has jumpers to clear the Real Time Clock (RTC) RAM in CMOS.

Clearing CMOS

To clear CMOS, follow these steps:

1. Temporarily set jumper Clear CMOS (CLRTC) to pins 1-2.
2. Wait 5-10 seconds and then return the jumper to pins 2-3.

When you startup the PC you will need to enter BIOS setup to reset any custom BIOS settings.

Clearing the BIOS password

The BIOS password is used to protect BIOS settings from unwanted changes. If you have forgotten your password you may disable password checking.
To erase the BIOS password follow these steps:

1. Turn OFF the computer and unplug the power cord.
2. Locate the jumper labeled Clear P.W. The jumper is found at the lower right edge of the motherboard.
3. Move the jumper on jumper Clear P.W. to pins 1-2.
4. Plug the power cord and turn ON the computer.

Hold down the F10 key during the startup process and enter BIOS setup to change or clear the password.

Product information

I think the only way past a forgotten BIOS password is a CMOS clear, which would involve dismantling the laptop to get to the motherboard and find a clear CMOS jumper, or pull the CMOS battery, which can be a risky maneuvre.

if youve forgotten the bios password you will need to remove the main battery, the power cord and disconnect the cmos battery to clear the bios password
its better to have a tech do this for you

A. By Using the Motherboard Jumper:

In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.

Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.

When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.

Make sure to turn the PC off before opening the cabinet and resetting the jumper.

Steps for Clearing BIOS Password Check

If users set BIOS Password (Supervisor Password and/or User Password) for a security reason, BIOS will ask
the password during systems POST or when systems enter to BIOS Setup menu. However, once it is
necessary to bypass the password check, users need to short the HW Gap to clear the password by the
following steps:
• Power Off a system, and remove HDD, AC and Battery from the machine.
• Open the back cover of the machine, and find out the HW Gap on M/B as picture.
• Use an electric conductivity tool to short the two points of the HW Gap.
• Plug in AC, keep the short condition on the HW Gap, and press Power Button to power on the
system till BIOS POST finish. Then remove the tool from the HW Gap.
• Restart system. Press F2 key to enter BIOS Setup menu.
• If there is no Password request, BIOS Password is cleared. Otherwise, please follow the steps and
try again.
NOTE: The steps are only for clearing BIOS Password (Supervisor Password and User Password).
