After a new dock, a new motherboard, etc... Problem came down to a driver. Given all the hardware replacements, I suspected it could be a software issue so I did a random google search and found this driver. It wasn’t listed for my laptop but I installed it and the issue is fixed! CPU now is speeding along at 3+ GHz while only powered by the dock.
I've been experiencing performance issues and noted in the Windows Task Manager Performance window that the CPU spends most of its time at 0.79 GHZ, even if CPU utilization is above 80%.. I've confirmed the following: Any ideas?
