HP pavilion screen capability

[phantomgsxr]

I recently was upgrading ram from 4gb to 8gb, 1tb ssd, and replacing the cmos battery for a family member in a HP15-f272wm. When I went to install the keyboard, the connector broke off of the motherboard. Womp, Womp. The original processor was Intel Pentium N3540 and only had 1 slot for Ram. When looking at repairing the motherboard or replacing it, I found it was just as cost effective to upgrade the motherboard to something a little better. I selected a Hp 15-n285eo energy star board with i5-4200u. Got the board in, installed in laptop and did a fresh install of windows 10. Almost everything is working great, and the speed of the computer is amazingly faster than the original board. Problem is the new board is not recognizing the laptop screen. I've tried everything including putting the old board back in where the screen comes on immediately. I'm thinking that even though the plug is the same maybe there is some wiring difference that maybe I can just swap out the wire. Everything works fine on an external monitor.

Hi @phantomgsxr,

Welcome to the HP Support Community! 

Thanks for reaching out about your query regarding your PC!

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

Try these steps:

Confirm Display Connector Compatibility

Identify Display Connector Type:

• Check the display cable and connector on your HP 15-f272wm screen. Typically, modern laptops have 30-pin or 40-pin connectors, which link the display to the motherboard.

Determine New Motherboard Connector:

• Verify the display connector type on the new motherboard you've selected. Ensure it matches the display connector from your original screen.

Compatibility Check

Ensure that the new motherboard is compatible with the laptop’s other components, including the display.

Power and Backlight Control:

• Beyond the physical connector, ensure that the new motherboard supports the same power and backlight control protocols as the original display.

Resolution and Refresh Rate:

• Verify that the new motherboard supports the screen's resolution and refresh rate. Most consumer-grade motherboards support a range of standard resolutions, but it’s always good to check.

Adapter Cables/Converters

If there are any compatibility issues with connectors:

1. Use Adapter Cables:
   • You can often find adapter cables that convert one type of display connector to another. For example, if the original screen uses a 30-pin connector and the new motherboard uses a different style, a conversion cable might solve the problem.

BIOS/UEFI Configuration

Changes in hardware, especially fundamental components like motherboards, may require adjustments in BIOS/UEFI:

1. Update BIOS/UEFI:
   • Once all components are installed, check the BIOS/UEFI settings to ensure the display is recognized and configured correctly.

I hope this helps.
