HP Envy X360 15M-cn0011dx motherboard upgrade

[ihikaru]

I currently have HP Envy X360 15M-cn0011dx with the Motherboard part #L19447-60.

     (Equipped with an Intel Core i5-8250U 1.60-GHz quad core processor (2400-MHz FSB, 6.0-MB L3 cache, 15.0-W), an Intel HD620 graphics subsystem with UMA video memory, and the Windows 10 operating system)

I want to upgrade it to have a stronger Graphics card and have a few sources to buy ones that have the added NVIDIA graphics card. Part numbers listed below. Can I swap out the motherboard with either of the part numbers below or is this not possible. It is in this model service manual.

Physically they will fit and all ports will line up and you have to source elsewhere because HP does not stock them

Thanks for the quick response . I have one more question on the matter. Would I have to upgrade anything else to make this work?

The reason I ask I vaguely remember when I purchased this laptop some of the upgrade options at the time required a display upgrade also. Was that because of preconfigured options or a limitation of the display?

Thanks,

Jake

Were you able to upgrade the motherboard? I was actually thinking of doing the same thing.
