Thanks for the quick response. I'll maybe take the case apart and see if there's anything obvious. But your replace/resell option might be the best option. Did similar thing with my daughter's Fujitsu Amilo (are we allowed to say these words on this forum! (
) and I did get back most of the outlay for the other laptop.
I did have a quick look for an R51 board on ebay (UK) but nothing come up.
On the other hand I only use this machine to control my music / media server in the living room so could probably get by with just using it on AC charger all the time.
(Great forum so far!)
