Max Core Frequency drop suddenly ??

[MoiDixMois]

hey everyone, i currently use Dell Inspiron 15 7000 gaming laptop with complete spesification
CPU : intel i7-7700HQ
GPU : Nvidia 1050ti
RAM : 16GB
SSD: 250GB
HDD: 1TB

i have this problem actually....for quite a long time, but i'm not really gaming in these past couple years and just recently want to dig in again in one of my favourite MMO, and i experience really bad drop FPS all of sudden, when i checked everything, i notice that my CPU Max Core Frequency for some reason dip in really low even thought temperature and everything is fine, heres the screenshot

as you see, the temps are fine, its well below 80%, and the memory usage also not even reach 50%, but look at the intel tuning utility, you can see big drop on the circle i draw, thats when the massive drop fps hit in, is there any reason for this?, please help !

thank you in advance

edit : and i also use max performance on the battery setting

check the power draw?

you meant the power draw from the socket ?, unfortunately i don't have the device to do that...but talking about that, i use APC surge protector on my socket to the splitter then to the laptop, can it be the cause ?

about the APC, i plugged it out, and try it out again, still have massive drop on max core frequency, so theres nothing about that lol, but about the power draw, still can't confirm, might need to buy a device for that

but is there any other reason other than that ?

cpu power draw. it only do the max turbo boost if both temp and power is under the spec
