re. Notebook UX430U flashing light does not go off after shut down

Hey there guys..

This is a question about an Asus Notebook UX430U (I could not find it in the list of models I´m afraid)…

When I shutdown the laptop a light continues to flash on the side - it has an image of a light bulb next to it. Any ideas what is up with my laptop? It did this in the past, so I took it to the repair shop, but all they did was reset it (and I lost everything on it).

It is happening again. I don´t think it simply needs a reset as I did that very recently. Any other ideas??

Thanks so much

Amy
