HP Envy DV7-7333cl Motherboard swap

[Xeper8x8]

I bought a HP Envy DV7-7333cl which has a CPU/motherboard issue as the blinking caps light indicated (it was super cheap and wanted a new project). The mobo was an AMD board and I wanted to swap out the board with an HP Envy DV7-7243cl Intel mobo I bought. So i install that intel board with a working intel CPU and everything minus a few screw holes was able to fit. After reassembly, i power on and it doesn't work. Charger port light isn't even coming on. No lights at all. No beeps. Nothing. I read that this swap could work, but I guess I was mistaken?

Hi @Xeper8x8,

Welcome to the HP Support Community.

Thank you for posting your query.

When swapping motherboards, especially between different models with distinct architectures like AMD and Intel, several considerations must be made to ensure functionality:

Compatibility Issues:

• Power Specifications: Ensure that the power requirements for the Intel motherboard match those of the AMD model. Discrepancies here could lead to power-related issues like the charger port light not coming on.
• Connector Differences: The power connector on the motherboard and other connectors (such as the display, keyboard, and other peripherals) might differ, leading to potential misalignment or connection problems.

BIOS Configuration:

• Each motherboard has specific BIOS requirements and might need certain settings adjusted for new components to work properly. Ensure that the BIOS setup is compatible with the transplanted components.

Drivers and Firmware:

• Verify that drivers corresponding to the Intel motherboard are installed. Sometimes, systems may not boot if the necessary firmware or drivers are not detected.

Battery and Power Supply:

• Make sure the battery and power adapter are compatible with the new Intel motherboard. Sometimes, a different motherboard might require a different power rating.

Grounding and Connections:

• Double-check all connections. Ensure that everything is grounded properly and securely connected. Loose cables or connectors can prevent the device from powering on.

Use of Original Parts:

• Ensure that any specific parts required for the Intel board are used. Sometimes, other components like RAM, the battery, or other peripherals might need to be replaced to match the new board.

Take care and have an amazing day!
