I couldnt find time to write an update my Toshiba Tecra S2's surgery. I took it apart over the December 25, holiday. I used precision screwdrivers, which was a mistake. The other ones I had didnt fit the screws, because the screwdriver tips were too big. The precision set was so small that it damaged many screwheads. I took everything apart based on irisvista.com and was able to put it back together and it is still alive.
The "power surge on hub port" message didnt go away, though. I was still able to use the USB ports. I have no disabled the USB controller from Device Manager and am not getting the error messages and the system runs fine. There's just one problem: I think I didnt get it all put back tightly enough. Something seems to be lose. The system would just pause sometimes and I'd have to knock on it to get it to resume working. It's not too bad, though. I'm OK with it.
