While that advice was good for 10 years ago, today's (namebrand) laptops have stellar battery management so all that work you are doing will likely cause the contacts to fail or you to wear out the plastic.
Such advice lives on in spite of advances in battery management.
I recently bought a laptop and I was given two conflicting pieces of advice regarding the battery and or battery life.
These were as follows:
1) You should really use the laptop on AC as the AC really uses and the replaces the battery power and it is not good to be using down the battery and charging it up all the time.
2)You should use the battery and not the AC as then the battery forgets it can hold a charge and becomes useless.
I am a student on the go so please help me or point me in the right direction as I really don't want to destroy my battery.
Thanks in advance.
