This sounds like one of two possible faults. The first is the CMOS battery for the BIOS. That clue came from the working condition after a cold start(unplugged, not just turned off) that forced the unit into factory reset because the BIOS got scrambled. The battery, keeps the clock running and the BIOS settings until power is returned. The cell may even be dead, causing the slow down and eventual loss of peripheral devices and then complete halt of the processor when the voltage drops too low. These random and unrelated faults are indicative of the CMOS battery failure. The older Satellite units had the CMOS split into two different cells and in two different locations making it a pain to replace. I don't know if that's one of those or not, a first look would tell.

For your possible battery problems have a look at this video - there are several more on Youtube. It will give you a good idea of what is involved in getting to the CMOS battery. I haven't looked at the video myself but some batteries are as accessible as remove a plate on the base of the laptop, others require a virtully complete stripdown.
I am going to be away until about the 22nd October. Time on-line will be reduced and my internet access may be limited. PMs may not be replied to as quickly as normal !
