[TJ8799]

OK here is the story this booted fine when I put the screen in 

now this morning push the power button 1 blink on the cap light and no video fan run dvd drive door opens 

now I tried and got it to boot again but then next time nothing at all when it did boot the touchpad muse froze and then is doing like I said above

reading on the net some say remove the dvd drive and it will work I did not and it did boot but then the next time it did not just the one brink on the cap light 

I also read it means the CPU is bad   I have not tried switching them yet as I have a second unit I can get a cpu (processor from)

Hi @TJ8799,

Welcome to HP Support Community.

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

It sounds like you're experiencing some complex issues with your HP DV7-4069WM laptop. The symptoms you’re describing—such as the blinking cap lock light, no video output, intermittent booting, and a frozen touchpad—could be indicative of several potential problems. Here’s a step-by-step approach to diagnosing and troubleshooting the issue:

1. Interpreting the Cap Lock Blink Code

The blinking Cap Lock light on HP laptops usually indicates a specific error code. The pattern of blinks can help identify the problem:

• One Blink: This often indicates a hardware problem or a power issue.
• Long Blink + Short Blinks: The pattern of blinks can give more precise information. Check the HP support website or your laptop's service manual to decode the exact meaning.

2. Check and Reseat Components

• Ensure the laptop is powered off and unplugged from any power source.
• Open the back panel and reseat the RAM modules. Try booting with one module at a time if you have more than one.
• If you're comfortable doing so, reseat the CPU. Ensure there’s no dust or debris in the socket.

Remove and Reseat the DVD Drive:

• Sometimes, removing the DVD drive can help. Try booting with and without it to see if there’s a difference.

3. Check for Faulty Hardware

• Since you have a second unit, swap the CPU to see if that resolves the issue. If the problem persists with the new CPU, it may not be the CPU causing the issue.:
• Connect an external monitor to see if the problem is related to the laptop's screen or the graphics subsystem.
• Disconnect all external devices (USB devices, external drives) and try booting again.

4. Inspect for Physical Damage

• Ensure that all internal cables and connectors are securely connected.
• Inspect the motherboard and other components for signs of physical damage or overheating.

5. Try a Hard Reset

1. Perform a Hard Reset:
   • Disconnect all power sources and remove the battery.
   • Press and hold the power button for 15-20 seconds.
   • Reconnect the battery and power adapter, then try to boot the laptop.

6. BIOS/UEFI Reset

1. Reset BIOS/UEFI:
   • If possible, enter BIOS/UEFI settings and perform a reset to default settings.

7. Check Power Supply

1. Test the Power Adapter:
   • Ensure that the power adapter is working correctly. If possible, test with another compatible power adapter.

I hope this helps.

Take care and have a good day.

I will try these thing I don't understand is 

the DVD drive Remove and Reseat the DVD Drive why does that work?

Hardware can that be a CPU ?  or mostly the motherboard

as sometimes it may show on a external screen but not the laptop screen even thro both the screen and video cable have been replaced

Thank you

Update

I took and did the list still did not show video after the 3rd restart so I took it apart cleaned the other Processor and switched  them out as I had a extra one from another board 

it booted on first try and booted three times no problem I went into windows no problems 

So either it was a bad CPU or maybe it was not locked in all the way

Fixed
