You had a bad fix. I had my 2.16 MBP ATI x1600 w/video artifacts fixed under Applecare last August just before the Applecare expired. Replaced logic board and it has worked fine since. When not mobile it Folds 24/7. Mine had a 90 day warranty on the fix because Applecare expired 2 days after I initially brought it in. Good thing, too, because the provider didn't get the fix right for 3 months - heat sink issues.
