So I have this new laptop at (my new) work.
I unplugged and re-plugged the charger, as you do, and discovered that the computer stated it was plugged, but was not charging.
Curious, I looked at my options/preferences, and found nothing.
Googled, and found a lot of people complaining about it. There was also a solution to it, http://jeffreypalermo.com/blog/plugged-in-not-charging-windows-7-solution/, which I was feeling a bit too lazy to try.
Talked to our IT guy, and he talked me through a few options but nothing seemed to sort it.
A bit of experimentation, and I figured that it charged when the battery was below 90%, but did not do that when it was above 90%.
And there it was. To me, it was a design feature.
And it makes perfect sense. By disabling the charging when the battery is 90% or above, it is avoiding unnecessary charge cycles. And that actually expands the battery life.
Apparently this is how Windows 7 rolls.
Has anybody else noticed this ? What is your take on it????
