I have a toshiba satellite C600 series laptop that I have been told the motherboard has died in. Up until this point, the only problems that I had with the machine was the charging port was loose. One night when the battery died and we tried to plug in the charger, it would not charge. I took it to Best Buy and they thought the charging port was bad. I didn't want to wait two weeks to find out if it was the port and took it to Staples. They did a "diagnostic" and said it was the motherboard. I took it apart before taking it to Staples to see if I could reset the charge port myself and found that it had slipped out of it's slot but did not appear to be broken.Off to Staples I went, paid $70 bucks and they said it was the motherboard, and it would be $300 to put in a new one. The one thing that I did note about the machine was that if I pushed the power button, the battery that does a have a wee bit of life would cause the machine's power light to blink yellow a couple of times, but would not power up.
My question is, would a machine still be able to somewhat power on if the motherboard was dead? Like I said, other than this problem, the machine has been good. Is it most likely the mother board, and if so, are there any other options besides replacing it or the entire machine?
