Hi @DeviAdhikari 

Welcome to the HP Support Community!

Thanks for posting your query! We're here to help you get back up and running.

It sounds like your HP Pavilion dv6 is powering on but failing to display anything, which could indicate a hardware issue. Here are some steps to troubleshoot the problem:

Step 1: Perform a Hard Reset

1. Turn off the laptop and unplug it from the power source.
2. Remove the battery (if removable).
3. Press and hold the Power button for 30 seconds to discharge residual power.
4. Reconnect the battery and power cable, then turn the laptop on.

Step 2: Check RAM Modules

1. Turn off the laptop and unplug it.
2. Open the back panel and locate the RAM modules.
3. Remove the RAM sticks and clean the contacts gently with a lint-free cloth.
4. Reinsert the RAM sticks securely or try swapping their positions.
5. If you have multiple RAM sticks, test the laptop with one stick at a time.

Step 3: Inspect the Display Cable

1. If you’re comfortable opening the laptop, check the internal display cable connection.
2. Ensure the cable is securely connected to the motherboard and the screen.

Step 4: Run Diagnostics

1. Turn on the laptop and repeatedly press the Esc key to access the HP Startup Menu.
2. Select Diagnostics (usually F2) and run a hardware test.
3. If the diagnostics fail, note the error codes for further troubleshooting.

Step 5: External Display Test

Even though you don’t have an external monitor, borrowing one or using a TV with HDMI or VGA input could help determine if the issue is with the screen or the graphics card.
