Uhm, so i am seriously freaking out right now. My MacBook pro may have just died.. I Got it 3 days ago (we are talking used here, its a early 2008). And Since i got it, it seems to have random shutdowns (more likely overheats), and went to sleep when i typed alot. I Was using it for 2 hours, and it has 15 minutes of battery left, So i got up to get the charger (we are talking 12 seconds here) and i get back and I'm playing on it still, (unplugged.) and suddenly it just died, shutdown, black screen, no fans, no hard drive noise. Plugged it in, reset the SMC, and still nothing when i press the power button. WTF! This IS the GPU Failing right? I Sure hope so.. I Scheduled an apple store appointment monday so i will be going this week, I am still in the 4 year replacement period, So i hope its the GPU, i wasn't getting lines or color problems except when lion loaded the login screen.. THIS IS A GPU FAILURE, RIGHT? Gahh.. I'm so sad right now.. edit: its been 15 minutes since this happened, and its now turning on.. Either way i am taking this thing to the apple store. Is my GPU Bad?
