i'd doubt it has anything to do with the battery, and i'd say it's 50-50 between the logic board and perhaps the display cabling to the inverter, the inverter itself, or maybe the display itself. depending on exactly what's causing this, it may or may not get worse... if it's the logic board, i'd say "no". if it's the video cable (i forget for the moment what it's specific name is), then the answer is probably "yes". everything else is gray. the fsck message is probably unrelated. personally, i suggest running the Disk Utility, while booted to the OS X install CD, rather than running fsck. after disk utility, i move on to DiskWarrior. -- G-Books is sponsored by <http://lowendmac.com/> and...
