Yep, plugged in it will charge the batteries (probably got a light to indicate charging).

Not come across one that doesn't (famous last words).

thanks 4 that info, the reason i ask is ive just bought a new battery and no light comes on 2 say its charging, i charged it turned on, i charged it 4 10 hours as recommened by the shop and it show 43% they told me to do this 3 days on the trot to maximise my batterys exsistence, perhaps if ive got turned off 2nite i will get 100%

Not knowing the specific computer model, I would say "probably" it is charging. I've not yet seen a computer that required to be running to be charged, but there just might be one...

Most laptops have a colored indicator light that illuminates if the battery is charging. e.g. My Acer shows an amber light while charging, which changes to a green light when the battery is fully charged.

It will charge faster while turned off too
