My A556 will only activate the Intel Turbo Boost Technology on the processor from a warm boot, i.e. a restart (with the machine already powered on). From a cold boot (anything coming from power off - i.e. power on with power button, resume from hibernate, resume from sleep) Turbo Boost does not function.
I am monitoring the CPU clock frequency (i.e. processor Turbo Boost function) with CPUID's Hardware Monitor program - although it's pretty obvious when it's not working as the laptop runs a LOT slower without it. (I noticed my laptop running more slowly a few months ago and made investigations; at first I was thinking it was thermally throttling but I am having no issues in that way.)
When Turbo Boost is working the CPU frequency will vary between 0.5GHz (low power idle) and 2.5GHz (turbo). When it is not working, the CPU remains stuck at 2.2GHz at all times (also meaning it consumes more power when it could be idle, which will affect battery life). (Yes this happens even when the CPU utilisation drops to near zero, there's not any active processes causing CPU load.)
How can I make this function work correctly from a cold boot please - such that I'm not having to restart my laptop straight after switching it on every time - and I can use the hibernate function and come back to a quickly running computer?
Further - the frequencies I am seeing do not correspond with what Intel says the processor is capable of. I'm assuming this is because of how Fujitsu set up the laptop, for thermal/power consumption etc reasons? Or is there something else wrong and is my laptop missing further performance capability? Intel suggest an 0.8GHz "TDP down", 2.3GHz base, 2.4GHz "TDP up" and 2.8GHz Turbo Boost frequency.

Further #2 - Windows 10's Task Manager doesn't register the actual CPU clock frequency - claiming a 2.3GHz CPU running at a 2.4GHz base frequency and never changing/updating to reflect the actual CPU clock, unlike other Win10 computers I am using which show a varying clock frequency with load. These same numbers are displayed also when the CPU is stuck at 2.2GHz.
