Ben: It appears that your "try gently squeezing along the top of the display housing" (actually along the left screen housing side) remedy best indicates the possible problem. Right now that's how I'm curing the anomaly for several hours relief per. Can you or anyone define exactly what this "dry joint" is (or why it's called that); do you mean a loose chip socket? I'm not squeamish about taking computers or electronics apart as I often do, so I'd like to go inside and fix the problem directly. Only thing is the Apple site has no schematics of of the PB 190 nor can Google dig up any (going to need one anyway to install a new far larger HD -- any maven recommendations?). Can anyone help me here besides a trek to TekServe? Thanks All! JimWG -- PowerBooks is sponsored by <http://lowendmac.com/> and...
