I have my battery at 95% and it's not charging while plugged in.

I'm using Windows 7 Ultimate.

Do you know if it might be a setting somewhere?

Here's a screenshot:

Yes, I get this occasionally, it is nothing to be worried about.

It depends on the make, model and version of your laptop. Some power circuits are different and do weird things.

My laptop usually goes to 100%, then 3 times a week, it discharges 5% and does what yours is, then usually goes back to 100% after a few hours.

As long as it is working, I would not be worried.

To add to this: It makes no sense to re-charge the battery if it's close to 100 % full. You always have a little self-discharge and constantly cycling the battery between discharging and charging is nonsense. That's why the electronics on most laptops/batteries prevent charging before it reaches a certain threshold which is somewhat below 100 %. – Johannes Rössel Aug 23 at 7:07

Battery level is not an exact science. Windows makes a good guess and only reports what the hardware is doing. I'm guessing your battery is actually full and it has made the choice to not charge.

Try calibrating your battery. Charge it to the max, use it without power until it completely dies, then fully charge it again.

Apple's description on how to do it.
