Laptops; battery or mains?
I've always operated my laptop on mains power at home under the assumption it would prolong battery life. While shopping for laptops for a friend yesterday I was advised by a computer shop owner this was totally incorrect, and that the lithium ion battery should be used to its maximum extent, only recharging when down to the last few percent. I missed the subtle points of the explanation but I think it was rather similar to the dreaded nicad memory problems of years ago. I thought that had long been laid to rest.
The next shop, where we finally purchased, was a multi-appliance centre who specialise in selling technology to those who know nothing, and the saleswoman said exactly the opposite. I know whose word I would take, but I'm interested in further opinions from the real experts, so naturally I came here!
