Is it good or bad to detach the power cord from my laptop when it's fully charged?

Question

Should I keep it always plugged in? For some reason I think this will burn th ebattery in the long run. (like it would with cell phones)

Answer 1

I think that just like most rechargeable batteries, it is a good idea to use it once in awhile, or it will not hold a charge and work as well as it should.

Answer 2

Here is the best procedure in dealing with battery charging issues with laptops. If the laptop's battery is less than 50%, you can continue using it until the battery runs down to below 20%, then you plug in the charger. If you are not going to use the laptop any further, you should shut down windows, do not close lid and keep in hibernation as the PC will get hot and not get a full charge. Full charging is best done when you're finished for the day and retire to bed at night, let the laptop charge and unplug the charger the next morning. The laptop's battery will be fully charged. Then if you start using it, you should just run on battery until it gets low and then plug in the charger. Don't run on full battery with the charger plugged in. It just shortens the battery's life. Remember that batteries may only last 1000 charges similar to phone batteries, whilst the cost for replacement of laptop batteries can cost $200 -$300. The other thing I heard from a shop assistant saying that some people run the laptop from the mains without installing the batteries. This is most discouraging because if the power supply gets cut, the PC's operating system will crash plus you run the risk of harddrive corruption and damage. If you want to run the laptop with the charger plugged in, it's fine if the battery levels are low because over time the charging process will bring the battery levels up, however, it will be over some time as the running laptop consumes power as well.

Answer 3

All rechargable batteries will run down eventually, no matter what you do, eventually slowing in their decline at about 80% of original capacity. Still usable, but not new, you can see.

Like most of the people above said, most laptops (and cellphones) are smart enough to unhook before too much current harms the battery, but truth be told, the extent of this is that it just declines in max charge a bit faster -nothing catostrophic, even when it does apply.

Seems to me like you can just leave it plugged in, anyway.

Answer 4

It's fine to leave the cord plugged in if you want to. The laptop knows to disconnect the battery once its done charging, so its not going to get burned out or anything.

On a side note, most modern cell phones are that way too: you can leave them plugged in if you want. Its just the old phones that you need to unplug when they're done.

Answer 5

once you're using your computer you hook the potential twine and unhook whilst it that is not in use, this provides you with optimal existence of your battery, yet once you're a hectic guy and could function your equipment everywhere (motor vehicle, Bus etc etc) I recommend the place hooking of potential twine isn't feasible, then why you hassle for the existence of the battery? replace it once you sense that is not serving you satisfactorily. yet once you're taking an prolonged backup from the battery you would be able to pick charging the battery and so which you hook your potential twine for that reason, do not attempt to warmth up the battery this might shorten the existence of the battery.

Answer 6

Most laptops run quicker from AC source the go slower to conserve battery life when on battery. The truth is that most batterries will go over the course of time.

Answer 7

The best thing you can do is remove the battery itself once it's fully charged and you still have a power outlet close by.

Answer 8

It is good to unplug it. Battery will last longer.
