Hello,
I've recently bought acer nitro 5 AN515-51
everything is working fine but when i'm using it in battery saver mode it enables and disables fans automatically in order to save energy. 
but each time i hear a little noise while it's enabling or disabling fans. 
is this a normal noise or i should contact the guarantee?

    The sounds are quite faint. I had to put on earphones and 100% volume to make them out. They may also be created by capacitive & inductive current changes in motor windings due to rotor start & stop inertia. All electrical motors display this inertial property if you listen for it when initially turning them on or off --- fridges and air conditioners are louder examples. If it was mine, I wouldn't be too concerned at this point. Still about a year left on the warranty anyway. :)   Jack E/NJ

    If the "little noise" sounds more like a "little click", this is normal for an electromechnical switch. Jack E/NJ
