I have an Inspiron 8600, 1.8GHz 2GB RAM. The system and software are fully updated. WinXP SP3 and all the fixes/updates. The computer has been running fine for a long time. Recently I was using it and it sudden;y became unusabley slow. Apparently what happened is the computer's Speedstep got stuck on ~600 MHz (593 was shown). Now I haven't changed any power properties, it was running on A/C with "Always On" selected. I don't know what changed, but it just bogged down. I rebooted it 3 time to see if it would clear up, but no luck. The only fix is I disabled Speedstep in the BIOS and now it runs fine. It's fine for now, but if I need to pack it up and take it somewhere the battery is going to dain Faaaassssttt! I saw a Speedstep patch for older machines, and older SP's but nothing that answers this issue. Speedstep has been working fine for years.
