I didn't know it kept charging when it was off. You would have to turn it back on just to see if it was charged all the way though. Or it wouldn't
matter, because it wouldn't be on to be using the charge up, right? Gah, I feel like such an idiot not knowing this stuff.
Yes as long as the laptop is plugged in, even if it's turned off, it's still charging the battery. And, much like a cell phone, it charges better
that way, with less background applications running.
The battery uses a chemical reaction, like all batteries. The more you charge it, the more deposits of crap for in the electrolyte, making it less
efficient, and reducing the batteries ability to hold a charge, and making it take longer to achieve a full charge.
Anyways, you said it's an HP. What model? I deal with, oh, around 10,000 HP laptops currently, several models, nx6110, 6710b, 6530p, 4510s.
Let me tell you, if you plan to replace the battery, be careful. We've tried several different manufactures to replace our batteries and so far HP
branded ones last twice as long as the replacements, and considering they charge 3 times what the replacements do, it makes sense.
You "can" crack open the battery and replace the lithium cells, they are the same you'd find in most old cameras, they look almost like a double a
battery but maybe 1/3 as long. I would avoid against this for a million and one reasons though, leave that to someone who knows what they are
Depending on your model of laptop from HP, you might be able to go to the HP software and drivers page and download the HP battery check tool. We use
this to verify battery integrity. Tiny little app that scans the battery and gives you the life span, expectancy, full charge ratio, amount of
charge cycles completed, date it was manufactured, and in advanced mode, the manufacturer.
If you have a "simplo" battery, I feel sorry for you, they die within 6 months.
