Hi all, I've had my Surface Pro 2 256/8 since release and all has been fine until (possibly) the firmware update. Turbo Boost was working fine and the CPU was going up to its maximum of 2.6Ghz but it is now seemingly capped at 2.23Ghz. I've checked in PC Settings, Task Manager and CPU-Z, the maximum that the CPU ever reaches is 2.23Ghz, as indicated. Anyone else experienced this? I have tried all power profiles (Performance, balanced, Power Saver and there's no difference). Thanks!
