I want to know is it advisable to use a laptop computer as far as possible on DC Power (Direct Power instead of Battery power) or one should use laptop computer same as our Mobile phone (On Battery power and should plug in only when battery is low on power).
Because i receive options in favour of both.
Many suggests that one should run a laptop computer on DC power as far as possible because running a laptop more over Battery power will reduce the battery performance and subsequently its backup capacity
And many suggests that one should not keep the laptop always on DC power as it will keep on over charging the battery and same as our mobile phone it will make battery life less effective.
So whom should i follow

Kindly, guide me.
Thanks all in advance
