Dell Laptop Stop Battery Recharging whilst on AC Power

Ok, so I have ordered a replacements Dell laptop battery for my Dell Inspiron Laptop.

As advised by a forum member, I have set custom battery charging via the BIO to 90% – 40% so that battery never reaches full charge and only trickle charges when battery hits near charge capacity.

I am wondering, I cannot see how to disable battery charging totally, so that if laptop remains docked for 2 or 3 weeks at a time, then I would prefer battery not to be charging.

In times gone bye, theree used to be an option for an switch under the keyboard to disable battery charging, but for nowadays, what is best option.

P.S. No option via my Dell BIOS to achieve this, so looking at a third party app, maybe?

I’m not sure … if there are third party software that can achieve this ….
but dell laptops comes with dell power manager , which is sorta same what u can do in BIOS

custom charge is fine …. if laptop is docked and connected to power supply 24/7

Set start charging  – 0 ( if start is greater … i’m not sure what will happen if charge % falls below start point )
set stop charging – between 60 – 80

after battery reach stop% , it stop charging .. windows show it’s plugged in ..but not charging which is good  ….. ( when u restart laptop , windows does check battery charge status …during that time u might see status as charging )
—————————————————————-
i would avoid any software that claims it stop battery from charging ,   lets say your working on laptop that is set not to charge or without battery  ….. now by chance there is power outage ….. because it’s set not to charge …. you will lose all work you have done and laptop will shut off instantly ……

so it’s best to keep it set -> stop charging after certain % ,in my opinion

It is an interesting scenario, looks like laptop manufactures have come to a generalisation that the power options they include in BIOS/OS is sufficient (acceptable) ;-)

Interesting exercise I thought
