m16 R2, Smart Charging
After an update a couple of days ago, my laptop now has Smart Charging enabled. Yep, thats great while I use it at my desk, but when I travel I need to disable this. After searching settings and googling for an hour I can find nothing on how to change the settings or disable.
Maybe its been there for a while, the last few days have been a lot hotter in my office and maybe it decided to enable it due to heat? Thats great, but I still need to be able to control it!
Microsoft says:
How to turn off Smart charging
Because each device manufacturer implements Smart charging in slightly ways, visit your device manufacturer’s website to learn how to turn it off for your device.
Of course there is no information on Smart Charging on the Dell website or in any Dell literature I can find.
Any ideas?

On most of Dell laptop BIOS settings menu, certain battery options are hidden until you enable the advanced menu. Not sure if it will work with your specific laptop because you neglected to disclose the laptop model, but it does not hurt to try.
To change it in UEFI/BIOS settings, accessing BIOS firmware settings via F2 at boot, look for Power menu. If your laptop has it, you will find Battery Configuration, disable adaptive and next to it, you will find Advanced Configuration. In this option, Enable Advanced Battery Charge Configuration option is disable by default. When enabled, Advanced Battery Charged maximizes battery health while still supporting heavy use during the work day. It's equivalent of smart charging as they both limiting the maximum charge the battery to 80% of its normal capacity if your laptop is plugged in for a long time. Depending on your laptop current settings, you must test with different options, reboot for it to take effect, then check to see if smart charging is turned off.
You can also check in Windows 10/11 for battery option and changing maximum charging capacity preset. Or, you can manually discharge the battery to below 20%, then fully charge the battery. If the battery can be charged to 100%, your smart charging has been turned off.
