I was helping a colleague with her macbook today and noticed the charge Light on the adapter doesn't light up at all, also it doesn't say that it is plugged in, however it actually is charging slowly.
Also the ethernet connection doesn't work at all. So she's currently using airport only.

Both of these happened at the same time recently. I assume it means she'll need some hardware repairs.

The system preferences says the ethernet cable is unplugged.

She "says" that the ethernet cable for her DSL connection at home seems to work.

I tested using a different cable, and checked with another device to see if her connection in the wall was working, and they are.

ideas?
