I just got back from vacation. My Macbook seemed to be having some issues when I first got back. For one, my battery status, which had always been normal, went to "replace soon." It also was very laggy and slow whenever I tried to open or close a computer. It seemed to be "freezing" a lot, per say. I uploaded my vacation pictures, then started backing up to Time Machine. I left my laptop unplugged, and had to leave my house. When I returned a few hours later, my computer would not start. I figured the battery was dead. Pressing the battery indicator button would not light up any lights, not even just one flashing. I plugged my laptop in and tried to start it again. I got the gear type noise and a white screen. Nothing else. I took the battery out and tried to start it again. Same thing. I let the battery fully charge and tried again. Same thing. Gerr. I tried pressing the "option" button while the computer was trying to start, to see if I could even get into my BootCamp Windows partition. When I did this, the mouse pointer showed up and I could move it with the trackpad, but neither partition loaded. So what's it sound like? Harddrive failure? The drive was not the original drive, it was one I upgraded and has been in there a little over a year. Also, I'm trying to figure out if my Time Machine back up completed before the computer died, for obvious reasons. I tried plugging it into my Windows laptop, but it does not detect it. I'm guessing it's formatted in a file system Windows doesn't recognize? Anyway to tell if it finished backing up?
