At least 12 hours if you've just bought it.

You can use the laptop while it is charging.

I have had laptops connected to their charging device plugged into a wall socket for weeks. Some but not all of them have had problems with their batteries loosing capacity. I suspect the deterioration is due to insufficient "intelligence" in the charger.

First time charging of modern Lithium ion batteries: often at least 12 hours (see the manual).

Subsequent charging cycles: Check the laptops battery status with software (usually installed on a laptop).

Older Nickel Cadmium batteries are a much different story: The NiCd battery should be regularly depleted (and not too slowly either) and recharged fully or a "memory" effect will come into play whereby the battery capacity is drastically reduced.

Sometimes about 3 to 5 hours. Some suggest the best way is to have two batteries used alternately to extend battery life.

Sometimes, there is an indicator that lights up (green) when the battery is at full charge.

12-23 hours is usually a good time frame for the first charge. Make sure you "exercise" the battery by draining and recharging it a few times. Now laptop batteries are almost always Li-ion rechargeable batteries (Li-ion batteries are not susceptible of being over charged if the voltage and current are correct), What's more, most modern laptops have the intelligence to control the charge cycle and stop the charging after the battery has been fully charged.

it all depends. a packard bell easy note 1 gig 232 second trans-second lasts about 1.25 hours, a macbook 2.4 ghz 999s second trans-second lasts 10.9 hours. if you get a 43997747aatuk you can down load 8832 gigs in 25 seconds and, oh. so yeah. now i am going to do some calculations and look at my new 342 hard drive processor! :-)

You should generally charge it whenever it gets low, but resist the temptation to either charge it all the time (can lessen battery life) or let it run down completely every time you use it (a popular myth based on what you used to have to do with old nickel cadmium rechargeable batteries).

Take some hours if laptop show green light then it is full charge. It depends upon the battery life.

Laptop batteries are generally looked after by intelligent chargers. There is monitoring electronics built into the battery itself and the computer also regulates the charging and operates indicators in software and harware (lights).

It is more important to occasionally exercise your battery, by running it on battery alone, to put it through a discharge cycle.

A laptop that is always used on mains power, may cause the battery to sulphate up, through lack of discharge cycle.

It is best to disconnect the charger from the wall socket when you are not using it or not in attendance.

A full charge is indicated differently depending on the make and model. Some have a red light to show charging and green for full. Others show a flashing light when charging and nothing when full. Check your manual.

If it is full and you are using it, carry on working, the charger will now provide power instead of the battery.

If the laptop is not being used and switched off, then remove the power when the indicators show full.

You can keep it plugged in charging forever without any long-term negative effects on your laptop or battery.

Impossible to answer specifically. The recharge time depends on whether the battery is fully or partially discharged - and the amount of amps the charger delivers to the battery..
