I’ve had this computer since the New Year, and when I first got it, a single charge would last about four hours. I looked down my nose at all the poor schlubs who, when entering a library or coffeeshop, had to duckwalk their way in, looking for a seat near an electrical outlet. But not me. I could depend on my battery for several hours if need be, even if it wasn’t topped up.
That was then.
Now I’m lucky to get forty-five minutes of use out of a battery charge. And I do know that they deteriorate over time, as this one was doing until about a week ago. I noticed that it was more like a couple of hours. But now it is so moribund that now, with a nearly full charge when I booted up just now, the life indicator says I have eighteen minutes left. I think it’s actually going to be less than that.
Is there any way to find out if one or more cells in the battery isn’t charging at all? Is there any way to restore battery performance?
