Restart your system and start taping F10 key and you may get an option to reset the password.
Note: You may have to open your Laptop, which may void the system warranty.

Reset the BIOS Password By Removing the CMOS Battery
One of the most common methods to reset the BIOS password is to remove or discharge the battery on the computer’s motherboard. If the power to the battery is lost or drained, the BIOS configuration will be reset to the factory state with no password. System settings made to the BIOS will also be lost.
Step 1 – Turn off the computer and ensure it has no external power (ie unplug the power cable. If it has a battery, remove it).
Step 2 – Open the computer’s case or box.
Step 3 – Locate the computer’s motherboard and look for the white silver button battery on the motherboard.
Step 4 – If the battery is not soldered to the motherboard, remove it carefully and wait for approximately 30 seconds.
Step 5 – Put the computer case back together and boot the computer.
Step 6 – If the “CMOS Checksum Error-Defaults Loaded” error message is displayed, the BIOS password has been reset.
In the event the CMOS battery is soldered to the computer’s motherboard, you will want to seek a different method to reset the BIOS password on the computer.

Reset the BIOS Password on a HP Compaq dc7800
The basic input/output system manages the operation of hardware in the HP Compaq dc7800. The PC allows users to make changes to the BIOS to alter how the computer and its devices behave. You can set up an administrative password in the BIOS to prevent employees from making changes to the dc7800 without permission. If you forgot the password to the BIOS and can no longer access the software, however, or if you failed to lock the program with a hard-to-guess password and a worker managed to access setup, you can reset the password either via the BIOS itself or by temporarily removing the battery.
From the BIOS
Step 1
Power on or reboot the HP Compaq dc7800. Press "F10" during the boot process before the operating system logo appears on-screen.
Step 2
Enter the administrative password. Press "F9" to reset the password and restore the BIOS to its default configuration.

Step 3
Press "F10" to save your changes and exit the BIOS.
Via the Hardware
Step 1
Turn off the dc7800. Unplug the power connector and all devices attached to the HP Compaq. Set the computer on its side.
Step 2
Loosen the thumbscrew found on the back of the computer, grip the indent on the cover and then slide the panel towards the front of the case.
Step 3
Lift the cover off the dc7800. Put a hand on the case to ground yourself and then find the coin-cell battery.
Step 4
Push down on or pull back the lever securing the battery to its holder, if applicable, and then lift the component out of its container.
Step 5
Wait 10 minutes before reinstalling the battery to reset the BIOS configuration.
Step 6
Return the battery to its holder with the positive side -- the side with the "+" symbol on it -- facing up.
Step 7
Push the lever back down, if applicable. Reassemble the computer case.
