I have never seen a macbook/MBP that doesn't have some defect or developed some defect over time. I have lost all confidence in Apple over the past year and a half - I need to make a spreadsheet to figure out how many macbooks and macbook pros I've had. They are really too many to count an it's not just bad luck. QC at Apple does simply not exist. Anyway enough of my daily rant. My girlfriend's macbook stopped working last night while we were watching a DVD. Before I rush off with it to the applestore, I thought I'd ask around here. Here are the details: Symptoms: While watching a DVD, the DVD stalled first, followed by a kernel panic. I restarted, it booted up as normal. Started the DVD again and within a few seconds, kernel panic. Rebooted, started a browser, kernel panic. So, I reset the PMU and PRAM and rebooted. watched a few minutes of the DVD and then kernel panic again. Rebooted, but it wouldn't reboot, just a white light not flashing and some humming sound. Kept holding and pressing the power button and eventually it started up with no backlight. Held down the power button again,it rebooted as normal. I inserted the Apple dvd and ran the disk repair and repair permissions function. It booted quite slowly, but without a problem. Rebooted and tried opening a browser = kernel panic within a few seconds. So I removed one ram module, rebooted and everything was fine. I put in another ram module that I know is ok and still kept getting kernel panics. It seems like this is a faulty ram slot, but what do I know? It's worked fine since October, except for the original display which was replaced and then a sporadic, daily backlight flicker... Any ideas if there's anything I've overlooked software wise? I hate giving Apple the computer to mess around with because they often mess up other things in the process of repair.... Thanks!
