 Enable Turbo boost on DC may be disabled in BIOS.

 

Other possibilities might be Advanced settings in the Power plan -> Processor Power Management -> Maximum processor state

 

You can find the Power plan settings in the Control Panel

WinKey+R -> type control and hit Enter -> Power options

 

Have a nice day!!

Just read your reply. if you mean enable turbo boost on Battery how much more than 2.7ghz on a 2.4ghz cpu will i get

The problem is with AC power, it slows to 0.38ghz as soon as i plug in the mains adapter (AC)

However i can not find turbo boost in the bios  there is no mention of it there (" Insyde F.28, 22/04/19" )

And as i've already stated i have exhausted all options on power management 

Minimum processor state 

 on battery 5%

 plugged in 100%

Maximum processor state         

 on battery 100%

 plugged in 100%

and just to try something backward i put minimum processor state to on battery 50 No change

Then i put it to 100% still no change

So i put it back to 5%

Where now ?
