problem with ac adaptador pavilion dv6645us

hi, i have a notebook hp pavilion dv6645us, and when i use with the battery the temperature its ok
here i have the values

hd 40
gpu:45
core1:35
core2:36
proccesor:34
all this values are celsius

but when i conect the ac adaptador, the temperature goes up

but a lot, i think a gpu its about: 52 the core 1: 48 , core 2 :48 and processor 48

its a big diference,its more than 46degrees , is it normal at the notebooks or what?

i tried to use the notebook without the battery when i use with the ac adaptor and its the same
i think its a problem about ac adaptor

 

When you plug it in, the laptop goes into High Performance mode. There is nothing wrong with the temps.

 

what's the voltage you are connecting it to? 110 or 240 V?

 

but i think, the temperature go to much high

my voltage its 240v
