1st post but here goes.
Owned Satellite Pro C650 for a year now and a wek ago just started smoking then went off.
I checked with my warranty & ran out on Sep 30.
Now my problem is i cannot seem to find info on the mobo that is inside.
I have not open or anything but where you put RAM chips you can see clearly a little square chip burnt.
So i would like to ask is this a common fault.
Also the model number of mobo so maybe i could get a replacement.
This is really a bad luck… It’s pity that your warranty ran out just before the motherboard died.
It sounds like an overheating issue…
What to say… in your case the motherboard needs to be replaced and a new part could be ordered from Toshiba ASP in your country.
But new motherboard is expensive…it’s one of the expensive notebook parts beside the notebook’s display… so not sure if it’s worth to replace the mobo in your case…
However, you can ask the ASP technician for a opinion… maybe you could get an second hand part…
