my computer was shut down improperly (abrupt power loss) and when i turned it back on my onboard ethernet ports dont have link lights.

any suggestions before i try to RMA this sucker?

So in the act of shutting your machine down, the LEDs that indicate ethernet activity somehow uprooted themselves from the PCB and ran away?

stuart, be nice.

onWiFi, tried rebooting or unplugging/reconnecting the ethernet cable?
