My daily driver is an old Dell Latitude D830 with a 2.2GHz T7500 CPU. I'm getting an odd problem with the CPU being stuck at 600MHz (3x200). Usually powering down, pulling the battery, then rebooting will restore to CPU to its rated speed. Looking at CPU-z the lowest multi is 6, so seeing it at 3 is kinda baffling. Anyone seen this before? Is it letting me know I need to start shopping for a new notebook or just an odd quirk?
