Toshiba Satellite U400 lights always on

A member of staff brought in their laptop which I'd fixed just the other day (they'd accidentally switched the wireless off). She was saying how the lights for the "soft keys" at the top of the keyboard were always on.

I thought this wasn't so much of a problem, but actually it probably wouldn't be too good wasting the battery so much. I looked into it. At first I thought it was set up through the BIOS. I found an "Illumition" setting mentioned in this post so I had a look. I switched it off. This had no effect though.

My next guess was to look into windows and the many Toshiba apps that they put on. These were all rubbish but found one which let you change the same setting in the BIOS.

I found it mentioned that it might be due to a Microsoft Update so I took it through System Restore to undo all the updates. This didn't have any effect either.

Finally I thought of taking the battery out and putting it back in (just to see what it looked like with the buttons not light up). Once I'd put the battery back in, the lights didn't light up. In fact they'd stopped lighting up altogether!

I rebooted a few times and it looks like it worked. I even turned on "Illumination" and the lights came back on. And on switching it off they turned off, beautiful.

So in conclusion. Just take the battery out and put it back in again. Also disconnect from power source.
