I was getting a twin pair of old Dell Latitudes ready for "Pandora" duty. After the Win10 installs were done one was fast and quick running at 2.8 mhz on the processor and all was good. The other was slow and sluggish with the processor stuck at .59 mhz. I'm thinking it must be Intel MB drivers or at worst BIOS issues, but why one and not the other? They are identical with the same Win10 install. I threw drivers at it and changed the power settings and the Advanced Power settings in Control Panel but no change. I finally changed out the 65 watt power adapter I was using for a 90 watt and away it went. Spiked right up to maximum CPU clock speed and was just like the other one.
Until now I had no idea a lessor wattage PS will severely clock throttle a laptop. Never heard of such.......
