NIC not shown in device manager, CQ58-241SO, win10

[SweDennis]

Hello,

trying to reinstall and breathe life into an old laptop for a friend of mine. Installing a fresh win10 worked fine, all is well, apart from the fact that the Ethernet NIC is not shown in device manager. It has off and on been acting up but not to the point of disappearing altogether. I've seen reports online of leaving the laptop without power, removing the laptop internal battery, and that is about the only thing I haven't tried so far. Installing the relevant drivers works fine, but once done the installer pukes with the error that no compatible hardware is found. The NIC was found and presented to the OS while running win8. The Bios also has a non editable entry saying factory installed OS win8.

Booting on a Linux stick, everything works just fine, so there's no hardware issue with the port, per-se.

There's also some resource conflict on one pci-pci bridge, but I have no idea which hardware component it pertains to, or if it's relevant.

Any tip? What info could I provide to help anyone else come up with an idea?

Regards,

/Dennis

Problem Solved:

Reverting BIOS back to F.27 from F.29 solved the issue.

As to why it worked with Linux, any flavour, even on F.29, is something I'm not in the mood to investigate fully, but either way, problem solved. Both issues got sorted at once, they were obviously connected, the resource conflict, and the NIC not showing up in device manager. No other changes were made, other than reverting the BIOS back one version.
