Hi @Solares,

Welcome to HP Support Community.

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

A black screen with a blinking Caps Lock key on your laptop can be indicative of several potential issues, often related to hardware or firmware problems. Here's a step-by-step approach to troubleshoot and resolve the issue:

**1. Identify the Blink Code

Count the Blinks:

• Observe the pattern of the Caps Lock blinking. The number of blinks and the pause between them can indicate specific error codes.

Check the Manual:

• Refer to your laptop's user manual or HP’s support website for information on blink codes related to your model. Each pattern typically corresponds to a specific issue.

**2. Perform a Hard Reset

Turn Off the Laptop:

• Press and hold the power button until the laptop completely shuts down. If the power button is unresponsive, you might need to disconnect the battery (if removable) and unplug the power adapter.

Unplug the Power Cord:

• Disconnect the power cord from the laptop.

Remove the Battery (if possible):

• If your laptop has a removable battery, take it out.

Hold the Power Button:

• Press and hold the power button for 15-30 seconds to discharge any residual power.

Reconnect and Power On:

• Reinsert the battery (if removed), plug in the power cord, and turn on the laptop.

**3. Check for External Connections

Disconnect Peripherals:

• Unplug all external devices connected to your laptop (USB drives, external keyboards, mice, etc.).

Power On the Laptop:

• Try to power on the laptop without any external peripherals connected to see if the issue persists.

**4. Inspect Hardware Components

Check RAM and Hard Drive:

• If you are comfortable working with internal components, ensure that the RAM and hard drive are properly seated. Loose connections can cause boot issues.

Listen for Beep Codes:

• If your laptop emits beep codes in addition to the blinking Caps Lock, refer to the beep code guide in your laptop’s manual for further diagnosis.

**5. Try Safe Mode or BIOS

Enter BIOS/UEFI:

• Restart the laptop and try to enter BIOS/UEFI settings by pressing the appropriate key (usually F2, F10, ESC, or DEL) during startup.

Check BIOS Settings:

• If you can access BIOS, verify that hardware settings are correct. Check for any obvious issues with settings related to boot devices.

Boot into Safe Mode:

• If possible, try to boot into Safe Mode. You may need to interrupt the boot process three times (by turning off the laptop during startup) to trigger Windows Recovery and access Safe Mode.

**6. Perform System Diagnostics

Run Built-In Diagnostics:

• Many laptops come with built-in diagnostic tools. Check your laptop’s manual or HP’s support site for instructions on running diagnostics.

I hope this helps.

Take care and have a good day.
