How To Disable Battery Charging In Windows 8

Blog

• #one

Hi, I have a DELL Latitude E4200 ultra portable laptop and I come across on the bios that you can disable battery accuse with a fn key combination, my question is: if I disable the battery accuse this way, does information technology mean that I can go out the laptop plugged in all day with out damaging the battery?

Yep, I imagine that's why the option is in that location. It's the frequent re-charging to go along the bombardment fully charged which somewhen "kills" the bombardment then that it tin can't hold a charge any longer.

Yet, you'll need to keep remembering to go back into BIOS Setup every few months to re-enable battery charging, don't let it stay completely apartment for a long catamenia (it volition lose accuse gradually over fourth dimension, even when non in use) equally that'southward just as bad as over-frequent charging.

The other alternative is exit battery charging enabled and just remove the battery instead ( every bit I do). Put it back every few months to check that information technology'southward charge per centum is not getting too low.

Yeah, I imagine that'due south why the choice is at that place. Information technology's the frequent re-charging to keep the battery fully charged which eventually "kills" the battery then that it can't agree a charge whatsoever longer.

All the same, you'll need to keep remembering to go back into BIOS Setup every few months to re-enable battery charging, don't let it stay completely flat for a long period (it will lose charge gradually over time, even when non in use) equally that's just as bad as over-frequent charging.

The other alternative is leave battery charging enabled and but remove the battery instead ( every bit I do). Put it back every few months to check that it's charge percent is not getting too low.

Yes, I imagine that'due south why the option is there. Information technology'due south the frequent re-charging to keep the battery fully charged which eventually "kills" the bombardment and then that information technology tin can't hold a charge whatever longer.

Nonetheless, you'll need to keep remembering to go back into BIOS Setup every few months to re-enable battery charging, don't permit it stay completely flat for a long menstruation (it will lose charge gradually over fourth dimension, even when not in use) every bit that'south but as bad as over-frequent charging.

The other alternative is exit battery charging enabled and just remove the bombardment instead ( as I do). Put it back every few months to check that it's accuse percentage is not getting also low.

Thanks a lot for your input, i can confirm this information as i recently asked a DELL representative over chat and said the aforementioned to me.

I prefer the option to have the bombardment in all the time since i motility a LOT i need to have information technology ready all the time and since the charge selection tin can be enabled on windows with a fn combo i will keep the battery in and when it reaches about 80% i will enable the accuse some times and so information technology volition not go empty ever.
