Hello Nairalanders. Please my laptop fan blows very loud and fast and it makes the battery run down too fast. I have cleared the ventilation outlet to no avail. Please I got some info online that too many programs are running on startup but I don't know which one to disable. Please help me out.

If your are using windows... Just go to battery settings . locate procesor managemet and you will see something like "active" , "passive".....enable "passive"
..
I encountered such and that solution helped me out
