Thanks for reaching out about your query regarding HP Laptop Power-On Issue! 

We're thrilled to have the opportunity to assist you and provide a solution.  

Your HP laptop exhibiting a sequence of three slow blue light blinks followed by three quick blinks on the caps lock key is indicative of a specific error that needs to be diagnosed. Here's a step-by-step guide to troubleshoot this issue:

Understand the Blink Codes:

• The blinking lights indicate a hardware error. The three blinks pattern could be related to a memory module error or another component failure.

Examine the Environment:

• Ensure all cables and connections are secure and not loose.
• Verify that your power sources (AC adapter or battery) are functional. Test with a known working AC outlet.

Perform a Visual Inspection:

• Check your laptop for any physical damage, such as a cracked display or signs of liquid spill, which might affect its functionality.

Update BIOS and Drivers:

• Although your laptop isn't powering on, once you resolve the issue, ensure to update BIOS and drivers to prevent future occurrences.

Remove and Reseat Memory Modules:

• Disconnect power and remove the battery if accessible.
• Open the laptop's memory bay cover and remove the memory modules.
• Clean any dust and carefully reseat the modules. Ensure they are properly secured.

HP PC Hardware Diagnostics:

• If possible, use the HP PC Hardware Diagnostics (UEFI) tool to run diagnostic tests outside the operating system.
• Quickly press esc then F2 when booting if the laptop powers on intermittently.  

Hope this helps!
