Blank Screen After Ram Upgrade

[Bj3331]

Hello,

I put in a new RAM card in my 14-dq0762dx (it's 10 days out of warranty now) anyway, the screen stays blank. The Caps Lock does 5 long blinks and 3 short. I've tried the BIOS reset, hard reset, removed the battery and put it back in and nothing. Even with the old RAM card it still won't boot up.

Hi @Bj3331,

Welcome to the HP Support Community! 

Thanks for reaching out about your query regarding your laptop!

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

In your situation where the screen remains blank after installing a new RAM card, and you're observing a pattern of 5 long blinks and 3 short blinks from the Caps Lock key, this blink code can help identify the issue. Here is a step-by-step guide to help you troubleshoot the problem:

Blink Code Interpretation: The pattern of 5 long blinks followed by 3 short blinks typically indicates a system board failure or issue related to the hardware based on the HP system validation diagnostic codes.

Reseat Memory Modules: It's advisable to reseat the memory modules. Remove the RAM and gently reinstall it to ensure proper contact. Make sure the module is compatible with your laptop model. If the system still does not boot after reinstalling the memory, try replacing the memory modules as a test (use verified working memory, if available).

Return to Original Configuration: Since the issue persists even after reverting to the original RAM module, reseat all connections and components. Ensure all internal cables are properly connected and securely seated.

Examine for Physical Damage: Inspect for any signs of mechanical damage or loose connections in the internal components. Also, check the memory slots for debris or damage.

System Board Diagnostics: Test the essential hardware configuration by using only essential components (system board, AC adapter, processor, memory, external VGA monitor, USB keyboard/mouse) to eliminate non-essential components as the cause.

HP Diagnostics: Utilize HP PC Hardware Diagnostics tools (UEFI) to test the memory and other major components if the system can be responsive enough to boot into diagnostics mode.

I hope this helps.
