Is it wise to leave a (fully charged) battery in a laptop while it is plugged into ac power plug. Will hurt or dimish the battery. Or is best use the ac plug and take the battery out while at home. I have a duo core chip.
look at your manual. some laptops say that the battery must be in while
if it allows you to run without the battery in then you could leave it
out. keeping a Li battery fully charged and warm (which it is in
your plugged in running laptop) will shorten its lifetime. people
do remove their batteries to keep them cooler and hopefully
extend their lifetime. if you do so be careful with the battery,
if it came with a plastic cap on the terminals then use that, or
put in a nonconductive bag. in some fashion you need to
prevent the battery from accidentally shorting, not only
bad for the battery but you can start your house on fire.
if you run without a battery then you are loosing its
functioning as a UPS. if you run throught an external
UPS then you are still good for that.
