Is this worth fixing?
3 days ago, My Macbook started crashing (giving me the Gray Screen of Death), but as long as I keep the internet off, it wouldn't crash. Last night my computer just shut off and now isn't turning on. Macbook doesn't even turn on. I push the power button, and the sleep light on the front comes on, but nothing happens. The screen stays black. No chime or tone or anything. It wasn't dropped, nor was anything spilled on it. My computer is 4 years old.
I tried unplugging it and remove the battery and holding down the start button for ten seconds. Still nothing. I also tried starting up from my system installation disk, still didn't go any further. and now my disk is stuck. Another thing I tried is starting up holding down the Option & Command and P and R keys. Still nothing.
The last 3 numbers of my S/N are U9C
I think it's a power control issue. Maybe I'm wrong on that? is it easily and/or cheaply fixed, or is this part of the logic board?
If it is the logic board, is it worth replacing on an old, 4 year old computer or just get a new one? I'm really at a loss for what to do here!
