Okay I own an early 2008 Macbook Pro. I've never had any major problems until now. Anyway I put my computer to sleep earlier by closing the lid, but when I opened it, the monitor still showed a black screen. I waited a bit but nothing happened, and I turned off the whole thing. When I tried to turn it on again, the machine makes the usual startup noise (hardware noise, NOT the bootup chimes), but the LCD remains black. There are no startup chimes. Also there's that white light indicator that tells you whether the Mac is sleeping or not...well, there's a faint white light on. My battery is at full charge, and it's plugged in. I'm guessing there's a potential motherboard/GPU failure or possibly even LCD failure, but I'd like to get everyone's opinions first before bringing it into the Apple shop tomorrow morning. In the event that there is a motherboard/GPU failure, is there a chance that I could be given a new Macbook Pro? There's a manufacturing defect with the LCD panel that's purely cosmetic and I was told that it warrants a replacement, but I haven't had the time to bring it in for it yet. Would the combined cost of a Motherboard + LCD replacement be enough to have them consider giving me a new Macbook Pro? Lastly, yes, it's still under warranty.
