I have an old Toshiba Satellite 1105 sitting around and it dosent work. However, Im pretty sure that ive determined the cpu is faulty. The laptop makes a strange, small whining sound when i hit the power button. Nothing starts up at all. But when i took the processor out, the fan and the cd drive started up. If its not the cpu, let me know. But what i really want to know is if buying a $100+ processor is worth it, or should i see if i can get a new laptop?
