I can't think what else it can be. I've reinstalled chipset drivers even system restored but there's no sign of the ethernet.
I did do a hard drive I had spare a Windows 10 installation on it via an external caddie just to play around with. I'm going to give that a go




If I can find it

Haven't you got a spare Wifi dongle kicking about?
Yeah dongle works fine but tbh I cant stand the white noise from the fan and nothing slows it down. After spending more time on it yesterday it seems it's a motherboard problem. I replaced the rear network/USB controller panel and it's the same. I've done every combo there is uninstalling chipset, BIOS, nothing works.
I've picked up an identical 2nd hand motherboard for £40 so I'm gonna give that a go. If that fails then its up for sale spares repairs.
Just as an after thought, other than the Lenovo all in one, what would be a decent one to get ?., cheap please say 8gb ram. I need an all in one as there's no room for a tower

Anybody know which capacitor could replace this one ? I can't seem to locate one.

I'd go for the next voltage up,
Usually caps fail because they are running tight to their voltage tolerance.
