Replacement x360 14c touchpad not recognized by Chromebook.

[andyglynn]

I've just bought a replacement touchpad for my HP x360 14c (M00314-001) to replace my previous cracked one. I've installed it in the laptop, but the machine isn't recognizing it.

The pad was brand new and sealed. Zif cables look undamaged and are tight in the connectors.

Things I've tried:

• Hard reset
• running evtest (not showing)
• Guest mode
• diagnostics app with 'input' flag enabled (not showing).

Anything else I could try? Still not sure whether this is a hardware or software problem. Considering a powerwash, but don't fancy going through the rigmarole unless I've exhausted every other option. I've seen some users have installed alternate drivers in linux, but it doesn't sound like that should be necessary.

The pad was from a 14c-CA0053DX and my laptop's a 14c-CA-0030ca. Even though the touchpad's part number's the same, could that make a difference?

Thanks in advance for any advice anyone has.
