Solved! CPU speed drops

[Bandead]

I have a
Dell Inspiron 5555 with an AMD A10-8700 1,80ghz Radeon R6,
Windows 10


and when i open a game, el cpu speed drops to 1.29,1.30

Laptop is always plugged
Power settings are 100% (Proessor, cooling and gpu)
Also disabled Power manager in the BIOS

i think it isnt heating bc it drop as soon as i open the game, and as soon as i close it, the speed freq goes up
the temp in iddle is 65° and when playing 80°

i know there are a lot of thread like this but didnt get a solution

CPU in iddle

Just opened a game

and just closed it

As you see, instantly drops from 2.70 to 1.29, and the speed rise again instantly when i close the game, so i dont think the temp is a problem
