We never use the hardware once we have diagnosed that it is faulty. Either we repair or replace it . Not try to power it in a 1000 times and wait for a miracle.
@akaasi@svsaravanan05 most imp : the life is determined purely by the quality of the electronic subcomponents like inductors , capacitors and resistors which out numbers the mechanical parts that make a fan a lifetime reliable product.
@adxtyahq yes. it will be too late before we realize we are asking it to think for us and we are just consuming what it gives. Our cognition skills are getting weaker. Use it for learning or learn from its thinking and try to reduce usage. else our software skill will diminish.
