Good news! I received my laptop back yesterday. I was given March 12th as the date the back ordered parts were going to be coming in, so I waited another week and called and left a message with the nice lady who was helping me. She called me back the same day and told me that the parts were coming in the next day or so and that I should have an update in a couple of days. She was right. The parts came in and the laptop was repaired the same day.
It works! It booted up quickly and I was all set. They sent a 2 CD recovery set and a Qosmio player recovery disc (still haven't figured out what good the TV tuner is). The one problem is that the battery will not charge. The laptop only works if it is plugged in, although the indicator light does go green after I have it plugged in for a long time and turned off. But, I can't complain really.
I still can't believe Toshiba took the laptop back and replaced the system board at no cost to me on a five year old laptop. Awesome.
On to my next project - I need to decide on which netbook to buy. =)
