Hello. I have Acer A5 515-41G  (Amd A12-9720P 2.7Ghz turbo 3.6ghz  , RX 540 2GB )
When the charger is not plug in, the processor frequency stay at 1,78 Ghz. I checked all the power plans, i search everything. It just dont want to go up to 2.7.
I watch a youtube video, and i change something in registry, something like instead of 2 i put 3. After that, the processor stayed frezzed at 2.7, nu matter what power plan i selected. 
So..... THEORETICAL the processor is abble to stay at 2.7 without the charger plug in. But practically he dont.
I reinstalled windows 10, i search everything.  
And before you ask, yes, the processor was working at 2.7 without charger before 
The multiplier is stuck on x18

    >>>I checked all the power plans>>>

    Check advanced plan power options and try setting max processor state to 90% on battery and plugged in. Not 100%.

    OHH, i just remember. About one year ago i had a similar problem (i think there was when all trouble starts)
    When i start my laptop without charger and If i had Balanced active and i wanted to switch to Performance, didnt work. I needed to restart the laptop while plugged in and select performance before i hit the restart button. And when connect/disconnect charger i had simillar problems.
    BUT WITH A RESTART I WOULD SOLVED THE PROBLEM (for the moment, untill next day :)) )
