Hi @Leader2,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

To resolve the issue of a flashing caps lock light on your HP laptop, which can indicate a BIOS or hardware issue, you can try reinstalling the BIOS using a bootable USB flash drive. Here’s how you can create a bootable flash drive and install the BIOS.

Prepare a Bootable USB Flash Drive for BIOS Recovery

Requirements:

• A working computer with internet access.
• A USB flash drive with at least 8GB of space.

Step-by-Step Guide:

Step 1: Download the BIOS Update

1. On a working computer, visit the official HP support website.
2. Search for your laptop model by entering the product name or serial number.
3. Navigate to the Drivers section and download the latest BIOS update for your model.
   • Ensure that you download the BIOS specific to your exact laptop model.

Step 2: Create a Bootable USB Drive

HP provides a tool called the HP BIOS Update Utility for creating a bootable USB drive to install BIOS. Follow these steps:

1. Insert your USB flash drive into the computer.
2. Run the BIOS update file that you downloaded earlier.
3. Select Create a recovery USB flash drive, and follow the on-screen instructions to create a bootable BIOS recovery USB.
   • The tool will format the USB drive and copy the necessary BIOS files onto it.

Step 3: Perform the BIOS Recovery on Your HP Laptop

Once the bootable flash drive is ready, follow these steps to install the BIOS on the malfunctioning HP laptop:

1. Turn off the laptop if it's powered on.
2. Insert the USB flash drive with the BIOS update into one of the USB ports of the laptop.
3. Turn on the laptop and immediately press the Windows key + B simultaneously, while also holding down the Power button for 2-3 seconds.
   • You may hear beeping sounds, and the screen may remain blank during this process.
4. Release the keys, and the laptop should automatically access the BIOS recovery from the USB drive.
5. Follow the on-screen instructions to reinstall the BIOS.

Note:

• If the Caps Lock Light is Flashing in a Specific Pattern, check the blink codes on HP’s website to identify the exact problem (e.g., hardware failure vs BIOS issue).
• If the recovery process fails, try a different USB flash drive or re-download the BIOS file.

I hope this helps.

Take care and have a good day.
