Hi abdo refky,
Unfortunately Dell systems do not allow disabling hyper threading. However, do let me know the reason why you are trying to do so. I can check and let you if there is an alternative.

well , i am using Ubuntu , my laptop came with Ubuntu pre-installed on it , that's good because u get the original drivers , and recovery of course .
the software spike's when i open the gnome ( desktop environment ) menu multiple time's ""it's activated by mouse touch "" and also sometimes if u open the menu the pc freez for 2 sec !
now if i try to open the menu by a shortcut key it's work perfectly ,
since
the clicking on the menu causing a small effect and the processor do the graphic (which i think cause no load at all
also the pc processor usage is 5-25 % and the processor frequency always run at 1200 MHZ ,, which jump to 2400 if there are load .
i thought to close the hyper threading to see if the bug will remain .
that spike's should not happen on core i3-3310M
here is a gnome picture . as u can see on the first picture the processor was running at 2400 MHZ with usage 4 % at the time

Hi abdo refky,
Request you to try the below steps:
(1) Turn on the computer.
(2) At the Dell logo, keep tapping F2 key.
(3) BIOS screen appears, move to advanced tab
(4) Select Intel speed step and disable it.
(5) Move to exit tab and select ‘exit saving changes’.
Check if the same issue happens. Do reply with your findings.
