Forgetting your BIOS password on your HP Elitebook 840 G5 can be a frustrating experience. It locks you out of essential system settings and can significantly hinder your ability to use your laptop. But don’t worry, you don’t have to resort to drastic measures like reinstalling Windows. This guide will walk you through various methods to reset your BIOS password, allowing you to regain access to your HP Elitebook 840 G5.

Understanding BIOS Passwords

Before diving into the reset process, let’s understand what a BIOS password is and why it’s important. The BIOS (Basic Input/Output System) is a fundamental software that controls your computer’s hardware components, including the hard drive, keyboard, and display. A BIOS password acts as a security measure, preventing unauthorized access to these settings.

Method 1: Using the HP BIOS Password Reset Utility

HP provides a dedicated utility to reset forgotten BIOS passwords on their laptops. This method is generally the simplest and most effective for HP Elitebook 840 G5 models.
1. Download the Utility: Visit the HP support website and search for “HP BIOS Password Reset Utility” for your specific model (HP Elitebook 840 G5). Download the utility and save it to a USB drive.
2. Create a Bootable USB Drive: Format the USB drive to FAT32 and extract the downloaded utility files onto it.
3. Boot from USB: Restart your HP Elitebook 840 G5 and press the appropriate key (usually F9 or F12) to enter the boot menu. Select the USB drive as your boot device.
4. Run the Utility: The HP BIOS Password Reset Utility will launch automatically. Follow the on-screen instructions to reset the password.
5. Reboot: Once the process is complete, reboot your HP Elitebook 840 G5. You should now be able to access the BIOS without a password.

Method 2: Using a CMOS Battery Reset

If the HP BIOS Password Reset Utility isn‘t available or doesn’t work for your specific model, you can try resetting the CMOS battery. This battery stores the BIOS settings, including the password.
1. Power Off: Completely shut down your HP Elitebook 840 G5 and unplug the power adapter.
2. Locate the Battery: Remove the bottom cover of your laptop. The CMOS battery is usually a small, round battery located near the motherboard.
3. Remove and Replace: Carefully remove the CMOS battery using a small screwdriver or tweezers. Wait for about 15-20 seconds before reinserting the battery.
4. Power On: Reassemble your laptop and power it on. The BIOS password should be reset.
Important Note: Removing the CMOS battery will reset all BIOS settings, including your boot order and other customizations.

Method 3: Using a Hardware Password Reset

Some HP Elitebook models might have a physical jumper on the motherboard that allows you to reset the BIOS password.
1. Locate the Jumper: Consult your HP Elitebook 840 G5’s service manual or online documentation to find the location of the BIOS password reset jumper. It is usually marked on the motherboard.
2. Reset the Jumper: Carefully move the jumper to the designated reset position. Refer to your manual for specific instructions.
3. Power On: Power on your HP Elitebook 840 G5 and access the BIOS setup. The password should be reset.
Caution: Incorrectly manipulating the jumper can potentially damage your motherboard. Only attempt this method if you are comfortable working with computer hardware.

Method 4: Contacting HP Support

If all else fails, it’s recommended to contact HP support for assistance. They may have additional solutions or tools to help you reset your BIOS password.
