A few weeks ago, listening to The Tech Guy Leo Laporte, I found out I have been operating, and advising people, on old information.
The modern day laptop batteries are just fine being plugged in pretty much all the time. I had been telling people to let them run down when you could, then when the system told you you were about out of power, to plug them in to help them get the most out of their life spans. Leo says that’s a procedure based on a study done years ago, and turns out it was flawed.
So, if you’ve been regularly running your battery down, so it lasts longer…don’t worry about it. Leaving it plugged in just fine.
