Hi @Mouth_A_Massy 

Welcome to the HP Support Community! We're here to help you get back up and running.

I understand the situation you are facing with your HP 14s‑dq0012na laptop. The blinking caps lock light pattern you described (five slow blinks followed by three quick blinks) indicates a hardware diagnostic code from the system. Let’s go through recommended steps to address this:

Step 1: Perform a Hard Reset

1. Disconnect the AC adapter and remove any external devices (USB drives, printers, etc.).
2. Press and hold the power button for about 15 seconds.
3. Reconnect the AC adapter (leave the battery in place if it is internal).
4. Press the power button to turn the laptop on.

Step 2: Check Display Output

• If the screen remains blank, connect the laptop to an external monitor using HDMI or VGA.
• Power on the laptop and check if the external display shows output. This helps confirm if the issue is with the internal display.

Step 3: Run HP Hardware Diagnostics

1. Turn off the laptop completely.
2. Press the power button and immediately start pressing the F2 key repeatedly.
3. This should open the HP PC Hardware Diagnostics UEFI screen.
4. Select System Tests → Extensive Test to check memory and hardware components.
5. Allow the test to complete and note any error codes.

Step 4: Use HP App – Diagnose & Fix

• If the laptop powers on and you can reach Windows, open the HP App.
• Select Diagnose & Fix to run automated troubleshooting for hardware and startup issues.

For detailed guidance, HP provides official instructions here:

The problem occurred again and to fix it i simply disconnected the battery, drained excess charge, then reconnected the battery and that seems to have fixed the problem.

Thank you for sharing the update. It’s good to know that disconnecting the battery, draining residual charge, and reconnecting it helped restore normal startup. 

That process essentially performs a hardware reset, clearing any stored electrical charge that may interfere with proper booting.

If you have any more questions or need further assistance, please don't hesitate to ask. We're here to help! 

Thanks again for your confirmation, and we wish you an amazing day ahead! 😊
