want system board for toshiba satellite100 laptop, model PSAA5C-TA102C,BEING DEFECTIVE REQUIRES TO BE REPLACED. CONFIRM AVAILABILITY AND COST ETC.
You will be hard pressed to find a dealer selling laptop parts. Go here and get on to Toshiba support for your "system board" which I interpret you mean a motherboard...
Laptop parts are as much available as any used desktop part. The difference being each part is usually specific to a particular model. So you have to get the exact part. While a desktop you can usually get away a part form a same model series.
