You are not the only one that gets this message. I got it too.
Actually I got two messages. The first one says that my battery is only capable of holding a certain % of its total capability. The second message says something about its having a certain % of what it is capable of holding now. I don't know exactly the difference but in looking at it, it might mean something like...
The laptop battery can only hold this % of charge, versus what it was when it was new. It is then that it says something like getting a new battery. Does it recognize that my battery is about 2 years old?
Then the 2nd message-
The laptop battery currently has this % of power left in it.
This may sound confusing, and my words are not exact since I do not have the laptop with me now. But I want to ask, is kde that smart now that it can tell what the capability of battery is now (in the first message), versus what it was when it was new? The second message was self explanatory, but the first message has me wondering.
I may be totally off-base with this, but I was just reading the difference between the two messages and trying to understand what it was saying.
