Any supertech guys here have any experience fixing a GW60?

I have one that decided to die after a great day at Luderitz.  slowly the screen died and now it wont boot up. 

I'd love to get the speeds off it as a momento, so was thinking that it may be possible to open it up and clean, and somehow try attach to a computer to download the final file from it.

Any (useful) suggestions anyone?

Thanks!
