This is in a Toshiba Tecra 8100 laptop. When I purchased this computer, Everest, Belarc Advisor and WinXP reported that the processor was a P3 Coppermine 650mhz. This machine began to run very slowly Saturday afternoon. Went to Properties in My Computer to verify that all 512 mb of PC 100 memory were being reported. Then I looked at the processor info. WinXP Pro reeported the processor to be a P3 328mhz - roughly half of the speed reported up to that time. The speed reported has since returned to 650 mhz and the computer speed is back where it has been. Running the computer from the power supply vs. battery alone made no difference.

What could cause this type of problem?

It might be underclocking the processor to save battery life/electricty, and reduce heat while idling. Were you doing more things when you saw the speed jump back up to 650mhz?

Yes. At that time, I was submitting a materials order to a vendor and involved in an online discussion. This computer connects to the Internet via a 3Com USB adapter.

To be clear, I was engaged in those activities at the time that this machine seemed to slow down as well as when the speed returned to 'normal'.
