Leaving a laptop on charge all the time?

[Radio Fixer]

My lady uses her laptop only for 1/2 an hour or so a few times a week.  But she leaves it at rest, plugged in and charging.  Is this a good thing for battery life or is it better to let it run down now and then and then give it some electron work out?

thanks Gary

I don't know my misses does the same where as I always turn the mains off on mine .
Both laptops are about two years old and as far as I can tell both batteries hold a good charge .
the instructions on my dell suggest removing the battery if used only on mains.

She doesn't use it on mains to work with Rob but only on down time which is most of it.

But thanks Gay

With modern laptops the battery technology is central to their design - there is no harm whatsoever in leaving them on charge - the battery packs themselves have an embedded processor and sensors and the chargers know exactly when to back off and exactly what charging profile is needed when the pack says it needs more Coulombs...

All very clever stuff.

Thanks Nick. As you say amazingly clever.
