@Anamaria02, Welcome to the HP Support Community!  

Thanks for reaching out about your query regarding HP Pavilion Laptop (Model 14-dv0511sa)! 

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

If your HP Pavilion laptop has stopped working but the start/stop button light and charging light are still functional, here are some steps you can follow to diagnose and, hopefully, resolve the issue:

Possible Causes

1. Power-related issues: Defective or insufficient power sources, poor connections.
2. Hardware failures: Issues with essential components such as the processor, memory, or graphics card.
3. Thermal-related issues: Problems with cooling components leading to overheating.
4. Diagnostical error messages: Issues during the Power-On Self-Test (POST).

Troubleshooting Steps

Perform a Hard Reset:

• Disconnect all external devices and peripherals.
• Unplug the AC adapter and remove the battery (if removable).
• Press and hold the power button for about 15 seconds to drain residual power.
• Reconnect the AC adapter (without battery) and try turning on the laptop.

Check the AC Adapter:

• Verify the functionality of the AC adapter alone. Test with a verified working adapter if available.
• Confirm that the battery is not depleted using HP PC Hardware Diagnostics (UEFI) tool.

Reseat Hardware Components:

• Disconnect and then reassemble significant internal components (memory, storage drive, etc.) to ensure they are correctly connected.
• Check for any signs of loose connections, bent pins, stray wires, dust accumulation, or nearly faulty parts (e.g., bulging/leaking capacitors).

Reset BIOS Settings:

• If you can access the BIOS, reset it to its default condition.
• This can often be done by pressing a specific key (such as F10, Esc, or Delete) during startup to access the BIOS setup.

Run Hardware Diagnostics:

• Use the HP PC Hardware Diagnostics (UEFI) tool to test essential components like the hard drive and memory.
• If available, use the Thermal Monitor tool to ensure cooling components are functioning correctly and your computer is not overheating.  

Hope this helps! 

Take care, and have an amazing day!
