Hi
The spec is as follows
HP Pavilion x360 convertible
SKU N7H15EA
i5 6200U
Bios F.28
SMBIOS 2.8
windows10 version 10.0.1041
8GB Ram
512 M2 drive
I have modified the power management several times to no avail, it is now on the same for both battery and mains But still has the mains problem of shutting down to 0.38ghz

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 ?
