Hi there.

Sometimes when I turn my laptop on in the morning it would have lost some of its charge and be on 93-97% of battery remaining. I have it plugged in, wth the battery in as well (Don't think that is a good idea though?) pretty much all the time, so maybe that has something to do with it.

What could be the cause of this? Hardware? The fact that I have both the battery + power in at the same time?

Its not a big problem as it doesn't affect performance or anything, but would be nice to know what is causing it/how I can fix it

I have a HP DV6-7215-tx

Thanks :)

You should run the HP Battery Check. Here is an article about testing and calibrating HP batteries.

Batteries only have a finite life - typically 500 or so charges before you start to see degradation and 1000 charges and they're history.

This shouldn't be the case for a three months old laptop though. Run the battery calibration as suggested before.

Generally laptops wont start to charge till they are depleted a reasonable amount to stop wasting charge/discharge cycles, are you actually using it on battery or just leaving it plugged in all the time using it on AC power exclusively?

The computer works fairly hard to turn on, running the CPU and HDD at full throttle to get the machine started as fast as possible, the battery may actually not drop for a while after starting up as the battery use has been minimized.

Could also be that the laptop is in sleep mode rather than off entirely.

If its not those things, you may just have a crap battery.
