I've got a C760 that's about 3.5 years old now and last week it just stopped working altogether. One minute it was working fine, then I closed the lid, opened it back up maybe 30 minutes later and it wouldn't turn on. Thinking it might be the battery, I hooked it up to AC power and let it sit for a while, but it still shows no signs of life (except the charge light comes on when on AC power).
I've tried holding down OK when powering on, tried to get to the diagnostic menu using D-M keys (and even Fn-D-M), but nothing ever happens. I thought maybe the battery was completely dead (original battery), so I ordered a new one, but it shows the same behavior with the new battery.
The only thing I haven't tried yet is the C760 Recovery Kit that I believe is supposed to help with bricked units. Before I take that step, does anyone have any thoughts on other things to try? Of course, I'll probably use this as an excuse to upgrade to a C3200, but it would be nice to get the C760 working at least one last time to get some files off of it. Thanks for any advice!
