I'm usually the go to guy with mac questions, but my girlfriend's sister and mom are both having problems with their MBP's both '07's. The sister's computer has gone into permanent caps lock and there's no way to shut it off. Restarts, SMC Resets, Pram resets...nothing out of luck...any advice? the mom's computer's idvd refuses to burn dvd's. itll go through the whole burn process and then say the disc is invalid. In both situations they've taken it to the apple store and haven't gotten any answers. I figured this would be my best option for getting an answer. Anyone experience this stuff/know what to do??
